# DS18B20 Module
| Since | Origin / Contributor | Maintainer | Source |
| :----- | :-------------------- | :---------- | :------ |
| 2014-12-08 | [Huang Rui](https://github.com/vowstar) | [Huang Rui](https://github.com/vowstar) | [ds18b20.lua](../../../lua_modules/ds18b20/ds18b20.lua) |
This Lua module provides access to [DS18B20](https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf) 1-Wire digital thermometer.
!!! note
The module requires `ow` C module built into firmware.
### Require
```lua
ds18b20 = require("ds18b20")
```
### Release
```lua
ds18b20 = nil
package.loaded["ds18b20"] = nil
```
## enable_debug()
Enables debug output of the module.
#### Parameters
None
#### Returns
`nil`
## ds18b20.read_temp()
Scans the bus for DS18B20 sensors (optional), starts a readout (conversion) for all sensors and calls a callback function when all temperatures are available. Powered sensors are read at once first. Parasite-powered sensors are read one by one. The first parasite-powered sensor is read together with all powered sensors.
#### Syntax
`read_temp(callback, pin, unit, force_search, save_search)`
#### Parameters
- `callback` function that receives all results when all conversions finish. The callback function has one parameter - an array addressed by sensor addresses and a value of the temperature (string for integer version).
- `pin` pin of the one-wire bus. If nil, GPIO0 (3) is used.
- `unit` unit can be Celsius ("C" or ds18b20.C), Kelvin ("K" or `ds18b20.K`) or Fahrenheit ("F" or `ds18b20.F`). If not specified (`nil`) latest used unit is used.
- `force_search` if not nil a bus search for devices is performed before readout. If nil the existing list of sensors in memory is used. If the bus has not been searched yet the search performed as well.
- `save_search` if not nil found sensors are saved to the file `ds18b20_save.lc`. When `read_temp` is called, list of sensors in memory is empty and file `ds18b20_save.lc` is present then sensor addresses are loaded from file - useful when running from batteries & deepsleep - immediate readout is performed (no bus scan).
#### Returns
`nil`
#### Example
```lua
local t = require("ds18b20")
local pin = 3 -- gpio0 = 3, gpio2 = 4
local function readout(temp)
if t.sens then
print("Total number of DS18B20 sensors: ".. #t.sens)
for i, s in ipairs(t.sens) do
print(string.format(" sensor #%d address: %s%s", i, ('%02X:%02X:%02X:%02X:%02X:%02X:%02X:%02X'):format(s:byte(1,8)), s:byte(9) == 1 and " (parasite)" or ""))
end
end
for addr, temp in pairs(temp) do
print(string.format("Sensor %s: %s °C", ('%02X:%02X:%02X:%02X:%02X:%02X:%02X:%02X'):format(addr:byte(1,8)), temp))
end
-- Module can be released when it is no longer needed
t = nil
package.loaded["ds18b20"] = nil
end
t:read_temp(readout, pin, t.C)
```
## ds18b20.sens
A table with sensors present on the bus. It includes its address (8 bytes) and information whether the sensor is parasite-powered (9-th byte, 0 or 1).
## ds18b20.temp
A table with readout values (also passed as a parameter to callback function). It is addressed by sensor addresses.
#### Notes
Other examples of using this module can be found in [ds18b20-example.lua](../../../lua_modules/ds18b20/ds18b20-example.lua) and [ds18b20-web.lua](../../../lua_modules/ds18b20/ds18b20-web.lua) files.

## ds3231setAlarm()
Set an alarm to be triggered on SQW pin. _alarm1_ has a precision of **seconds**; _alarm2_ has a precision of **minutes** (`second` parameter will be ignored). Alarms sets gpio.LOW over the SQW pin and let it unchanged until reloaded. When reloaded sets gpio.HIGH. Alarms trigger **only once**, after that, if you want them to trigger again, you need to call `reloadAlarms()` or `setAlarm(...)` again.
Alarm type set the alarm match conditions:
- `ds3231.EVERYSECOND` works only with _alarm1_ and triggers every second;
- `ds3231.EVERYMINUTE` works only with _alarm2_ and triggers every minute (at 00 seconds);
- `ds3231.SECOND` triggers when time match given `seconds` parameter;
- `ds3231.MINUTE` triggers when time match given `seconds` and `minutes` parameters;
- `ds3231.HOUR` triggers when time match given `seconds`, `minutes`, and `hours` parameters;
- `ds3231.DAY` triggers when time match given `seconds`, `minutes`, and `hours` on week day `date/day` parameters;
- `ds3231.DATE` triggers when time match given `seconds`, `minutes`, and `hours` on date (day of the month) `date/day` parameters;
#### Syntax

#### Parameters
- `alarmId`: 1-2
- `alarmType`: 1-7
- `seconds`: 00-59
- `minutes`: 00-59
- `hours`: 00-23
- `date/day`: 01-31 or 1-7 (Sunday = 1, Saturday = 7)
#### Returns
`nil`
#### Example
```lua
i2c.setup(3, 4, scl, i2c.SLOW) -- call i2c.setup() only once
ds3231=require("ds3231")
-- Setting PIN1 to triggers on interrupt when alarm triggers
gpio.mode(1,gpio.INT)
gpio.trig(1,'down',function(level)
print('Time is passing')
-- If not reloaded it will be triggered only once
ds3231.reloadAlarms()
end)
ds3231.setAlarm(2,ds3231.EVERYMINUTE)
-- Don't forget to release it after use
ds3231 = nil
package.loaded["ds3231"] = nil
```
## ds3231.reloadAlarms()
Reload an already triggered alarm. Otherwise it will never be triggered again. There are two different alarms and they have to be reloaded both to let, even only one, to be triggered again. So there isn't a param to select which alarm to reload.
#### Syntax
`ds3231.reloadAlarms()`
#### Parameters
None
#### Returns
`nil`
#### Example
```lua
i2c.setup(3, 4, scl, i2c.SLOW) -- call i2c.setup() only once
ds3231=require("ds3231")
-- Setting PIN1 to triggers on interrupt when alarm triggers
gpio.mode(1,gpio.INT)
gpio.trig(1,'down',function(level)
print('Time is passing')
-- If not reloaded it will be triggered only once
ds3231.reloadAlarms()
end)
ds3231.setAlarm(2,ds3231.EVERYMINUTE)
-- Don't forget to release it after use
ds3231 = nil
package.loaded["ds3231"] = nil
```
## ds3231.enableAlarm()
Enable an already setted alarm with the previous matching conditions. It reloads alarms internally.
#### Syntax
`ds3231.enableAlarm(alarmId)`
#### Parameters
`alarmId`: 1-2
#### Returns
`nil`
#### Example
```lua
i2c.setup(3, 4, scl, i2c.SLOW) -- call i2c.setup() only once
ds3231=require("ds3231")
-- Trigger on x:20:15
ds3231.setAlarm(1,ds3231.MINUTE,15,20)
if badThing == 1 then
ds3231.disableAlarm(1)
end
if goodThing == 1 then
ds3231.enableAlarm(1)
end
-- Don't forget to release it after use
ds3231 = nil
package.loaded["ds3231"] = nil
```
## ds3231.disableAlarm()
Disable an already set alarm with the previous matching conditions.
if _alarmId_ is not 1 or 2 it disables both alarms.
**Warning**: `disableAlarm()` prevent alarms to trigger interrupt over SQW pin but alarm itself will triggers at the matching conditions as it could be seen on _status byte_.
#### Syntax
`ds3231.disableAlarm(alarmId)`
#### Parameters
`alarmId: 0-2`
#### Returns
`nil`
#### Example
```lua
i2c.setup(3, 4, scl, i2c.SLOW) -- call i2c.setup() only once
ds3231=require("ds3231")
-- Trigger on x:20:15
ds3231.setAlarm(1,ds3231.MINUTE,15,20)
if badThing == 1 then
ds3231.disableAlarm(1)
end
if goodThing == 1 then
ds3231.enableAlarm(1)
end
-- Don't forget to release it after use
ds3231 = nil
package.loaded["ds3231"] = nil
```
## ds3231.getBytes()
Get bytes of control, for debug purpose, and status of DS3231. To see what they means check the [datasheet](http://datasheets.maximintegrated.com/en/ds/DS3231.pdf).
#### Syntax
`ds3231.getBytes()`
#### Parameters
None
#### Returns
- `control`: integer. Control 0-255
- `status`: integer. Status 0-143 (bit 6-5-4 unused)

ds3231=require("ds3231")
control,status = ds3231.getBytes()
print('Control byte: '..control)
print('Status byte: '..status)
-- Don't forget to release it after use
ds3231 = nil
package.loaded["ds3231"] = nil
```
## da3231.resetStopFlag()
Stop flag on status byte means that the oscillator either is stopped or was stopped for some period and may be used to judge the validity of the timekeeping data. When set to 1 this flag keeps that values until changed to 0. Call `resetStopFlag()` if you need to check validity of time data after that.
#### Syntax
`ds3231.resetStopFlag()`
#### Parameters
None
#### Returns
`nil`
#### Example
```lua
i2c.setup(3, 4, scl, i2c.SLOW) -- call i2c.setup() only once
ds3231=require("ds3231")
control,status = ds3231.getBytes()
if bit.band(bit.rshift(status, 7),1) == 1 then
print('[WARNING] RTC has stopped')
ds3231.resetStopFlag()
end
-- Don't forget to release it after use
ds3231 = nil
package.loaded["ds3231"] = nil
```

# FTPServer Module
| Since | Origin / Contributor | Maintainer | Source |
| :----- | :-------------------- | :---------- | :------ |
| 2018-07-02 | [Terry Ellison](https://github.com/TerryE) | [Terry Ellison](https://github.com/TerryE) | [ftpserver.lua](../../../lua_modules/ftp/ftpserver.lua) |
This Lua module implementation provides a basic FTP server for the ESP8266. It has been tested against a number of Table, Windows and Linux FTP clients and browsers.
It provides a limited subset of FTP commands that enable such clients to transfer files to and from the ESP's file system. Only one server can be started at any one time, but this server can support multiple connected sessions (some FTP clients use multiple sessions and so require this feature).
!!! warning
This module is too big to load by standard `require` function or compile on ESP8266 using `node.compile()`. The only option to load and use it is to use [LFS](../lfs.md).
### Limitations
- FTP over SSH or TLS is not currently supported so transfer is unencrypted.
- The client session , must, authentical against a single user/password.
- Only the SPIFFS filesystem is currently supported, so changing directories is treated as a NO-OP.
- This implementation has been optimized for running in LFS.
- Only PASV mode is supported as the `net` module does not allow static allocation of outbound sockets.
### Notes
The coding style adopted here is more similar to best practice for normal (PC) module implementations, as using LFS permits a bias towards clarity of coding over brevity. It includes extra logic to handle some of the edge case issues more robustly. It also uses a standard forward reference coding pattern to allow the code to be laid out in main routine, subroutine order.
Most FTP clients are capable of higher transfer rates than the ESP SPIFFS write throughput, so the server uses TCP flow control to limit upload rates to the ESP.
The following FTP commands are supported:
- with no parameter: CDUP, NOOP, PASV, PWD, QUIT, SYST
- with one parameter: CWD, DELE, MODE, PASS, PORT, RNFR, RNTO, SIZE, TYPE, USER
- xfer commands: LIST, NLST, RETR, STOR
This implementation is by [Terry Ellison](https://github.com/TerryE), but I wish to acknowledge the inspiration and hard work by [Neronix](https://github.com/NeiroNx) that made this possible.
## createServer()
Create the FTP server on the standard ports 20 and 21. The global variable `FTP` is set to the server object.
#### Syntax
`FTP.createServer(user, pass[, dbgFlag])`
#### Parameters
- `user`: Username for access to the server
- `pass`: Password for access to the server
- `dbgFlag`: optional flag. If set true then internal debug output is printed
#### Returns
`nil`
#### Example
```Lua
require("ftpserver").createServer('user', 'password')
```
## open()
Wrapper to createServer() which also connects to the WiFi channel.
#### Syntax
`FTP.open(user, pass, ssid, wifipwd, dbgFlag)`
#### Parameters
- `user`: Username for access to the server
- `pass`: Password for access to the server
- `ssid`: SSID for WiFi service
- `wifipwd`: password for WiFi service
- `dbgFlag`: optional flag. If set true then internal debug output is printed
#### Returns
`nil`
#### Example
```Lua
require("ftpserver").open('myWifi', 'wifiPassword', 'user', 'password')
```
## close()
Close down server including any sockets and return all resources to Lua. Note that this include removing the FTP global variable and package references.
#### Syntax
`FTP.close()`
#### Parameters
None
#### Returns
`nil`
#### Example
```Lua
FTP.close()
```

# DS18B20 Module
This is a Lua module for the DS18B20 1-Wire digital thermometer.
## Require
```lua
ds18b20 = require("ds18b20")
```
## Release
```lua
ds18b20 = nil
package.loaded["ds18b20"]=nil
```
# Methods
## read_temp()
Scans the bus for DS18B20 sensors (optional), starts a readout (conversion) for all sensors and calls a callback function when all temperatures are available. Powered sensors are read at once first. Parasite-powered sensors are read one by one. The first parasite-powered sensor is read together with all powered sensors.
The module requires `ow` module.
#### Syntax
`read_temp(callback, pin, unit, force_search, save_search)`
#### Parameters
- `callback` function that receives all results when all conversions finish. The callback function has one parameter - an array addressed by sensor addresses and a value of the temperature (string for integer version).
- `pin` pin of the one-wire bus. If nil, GPIO0 (3) is used.
- `unit` unit can be Celsius ("C" or ds18b20.C), Kelvin ("K" or ds18b20.K) or Fahrenheit ("F" or ds18b20.F). If not specified (nil) latest used unit is used.
- `force_search` if not nil a bus search for devices is performed before readout. If nil the existing list of sensors in memory is used. If the bus has not been searched yet the search performed as well.
- `save_search` if not nil found sensors are saved to the file `ds18b20_save.lc`. When `read_temp` is called, list of sensors in memory is empty and file `ds18b20_save.lc` is present then sensor addresses are loaded from file - usefull when running from batteries & deepsleep - immediate readout is performed (no bus scan).
#### Returns
nil
#### Example
```lua
local t = require("ds18b20")
local pin = 3 -- gpio0 = 3, gpio2 = 4
local function readout(temp)
if t.sens then
print("Total number of DS18B20 sensors: ".. #t.sens)
for i, s in ipairs(t.sens) do
print(string.format(" sensor #%d address: %s%s", i, ('%02X:%02X:%02X:%02X:%02X:%02X:%02X:%02X'):format(s:byte(1,8)), s:byte(9) == 1 and " (parasite)" or ""))
end
end
for addr, temp in pairs(temp) do
print(string.format("Sensor %s: %s °C", ('%02X:%02X:%02X:%02X:%02X:%02X:%02X:%02X'):format(addr:byte(1,8)), temp))
end
-- Module can be released when it is no longer needed
t = nil
package.loaded["ds18b20"]=nil
end
t:read_temp(readout, pin, t.C)```
## enable_debug()
Enables debug output of the module.
# Properties
## sens
A table with sensors present on the bus. It includes its address (8 bytes) and information whether the sensor is parasite-powered (9-th byte, 0 or 1).
## temp
A table with readout values (also passed as a parameter to callback function). It is addressed by sensor addresses.

# FTPServer Module
# FTP Server Module
This Lua module implementation provides a basic FTP server for the ESP8266.
It has been tested against a number of Table, Windows and Linux FTP clients
and browsers.
It provides a limited subset of FTP commands that enable such clients to
tranfer files to and from the ESP's file system. Only one server can be
started at any one time, but this server can support multiple connected
sessions (some FTP clients use multiple sessions and so require this
feature).
### Limitations
- FTP over SSH or TLS is not currently supported so transfer is unencrypted.
- The client session , must, authentical against a single user/password.
- Only the SPIFFS filesystem is currently supported, so changing directories is treated as a NO-OP.
- This implementation has been optimised for running in LFS.
- Only PASV mode is supported as the `net` module does not allow static allocation of outbound sockets.
### Notes
The coding style adopted here is more similar to best practice for normal (PC)
module implementations, as using LFS permits a bias towards clarity of coding
over brevity. It includes extra logic to handle some of the edge case issues more
robustly. It also uses a standard forward reference coding pattern to allow the
code to be laid out in main routine, subroutine order.
Most FTP clients are capable of higher transfer rates than the ESP SPIFFS write
throughput, so the server uses TCP flow control to limit upload rates to the
ESP.
aThe following FTP commands are supported:
- with no parameter: CDUP, NOOP, PASV, PWD, QUIT, SYST
- with one parameter: CWD, DELE, MODE, PASS, PORT, RNFR, RNTO, SIZE, TYPE, USER
- xfer commands: LIST, NLST, RETR, STOR
This implementation is by Terry Ellison, but I wish to acknowledge the inspration
and hard work by [Neronix](https://github.com/NeiroNx) that made this possible.
## createServer()
Create the FTP server on the standard ports 20 and 21. The global variable `FTP`
is set to the server object.
#### Syntax
`FTP.createServer(user, pass[, dbgFlag])`
#### Parameters
- `user` - Username for access to the server
- `pass` - Password for access to the server
- `dbgFlag` - optional flag. If set true then internal debug output is printed
#### Returns
- N/A
#### Example
```Lua
require("ftpserver").createServer('user', 'password')
```
## open()
Wrapper to createServer() which also connects to the WiFi channel.
#### Syntax
`FTP.open(user, pass, ssid, wifipwd, dbgFlag)`
#### Parameters
- `user` - Username for access to the server
- `pass` - Password for access to the server
- `ssid` - SSID for Wifi service
- `wifipwd` - password for Wifi service
- `dbgFlag` - optional flag. If set true then internal debug output is printed
#### Returns
- N/A
#### Example
```Lua
require("ftpserver").open('myWifi', 'wifiPassword', 'user', 'password')
```
## close()
Close down server including any sockets and return all resouces to Lua. Note that
this include removing the FTP global variable and package references.
#### Syntax
`FTP.close()`
#### Parameters
- none
#### Returns
- nil
#### Example
```Lua
FTP.close()
```
Documentation for this Lua module is available in the [ftpserver.md](../../docs/en/lua-modules/ftpserver.md) file and in the [Official NodeMCU Documentation](https://nodemcu.readthedocs.io/) in `Lua Modules` section.

HDC1000 NodeMCU module
=======================
# HDC1000 Module
Here's my NodeMCU module for the TI HDC1000 temperature and humidity sensor. It should work with the HDC1008 too but I haven't tested it.
### Setup your sensor:
First, require it:
`HDC1000 = require("HDC1000")`
Then, initialize it:
```lua
i2c.setup(0, sda, scl, i2c.SLOW) -- call i2c.setup() only once
HDC1000.setup(drdyn)
```
If you don't want to use the DRDYn pin, set it to false: a 20ms delay will be automatically set after each read request.
`HDC1000.init(sda, scl, false)`
Configure it:
`HDC1000.config()`
Default options set the address to 0x40 and enable both temperature and humidity readings at 14-bit resolution, with the integrated heater on. You can change them by initializing your sensor like this:
`HDC1000.config(address, resolution, heater);`
"resolution" can be set to 14 bits for both temperature and humidity (0x00 - default) 11 bits for temperature (0x40), 11 bits for humidity (0x01), 8 bits for humidity (0x20)
"heater" can be set to ON (0x20 - default) or OFF (0x00)
### Read some values
You can read temperature and humidity by using the following commands:
`temperature = HDC1000.getTemp()` in Celsius degrees.
`humidity = HDC1000.getHumi()` in %
### Check your battery
The following code returns true if the battery voltage is <2.8V, false otherwise.
`isDead = HDC1000.batteryDead();`
Happy making! Also, check out my Breakout Board and Arduino library for this chip: http://b.truzzi.me/hdc1000-temperature-and-humidity-sensor-breakout-with-arduino-library/.
Documentation for this Lua module is available in the [hdc1000.md](../../docs/en/lua-modules/hdc1000.md) file and in the [Official NodeMCU Documentation](https://nodemcu.readthedocs.io/) in `Lua Modules` section.
