By the time we get informed that there's an LFS reload we've already
opened all the user libraries as well, so it's not safe to simply redo
that with a new lua_State. Currently that results in a hang, and a
manual reset is required to progress. Doing the automatic restart is
the correct approach here, even though this adds another reboot to the
LFS reload process.
Also fixed up a couple of minor issues when embedded-LFS is used.
With the switch to use the IDF's stdin for feeding the Lua VM, we
unintentionally lost the ability to use uart.on('data') on the console uart.
This is since we no longer install the nodemcu uart driver on said uart.
In order to resolve this shortcoming, this commit refactors the uart.on('data')
delimiter handling and moves it away from platform.c into uart.c where it
really belongs. A new function, uart_feed_data(), is introduced, which is used
both by the nodemcu uart driver task as well as the nodemcu console driver
task (assuming the console is in fact a uart).
The linebuffer allocation/freeing is still in response to
uart.start()/uart.stop(), but it is now in uart.c rather than
platform.c.
The whole uart integration is still too tightly coupled between the platform
component and the module component's uart.c, but this makes it slightly
better at least.
* Ported rotary driver. Compiles but not tested.
* Added the rotary switch driver to the esp32 version
* Review comments. Also ensure that we have GPIO if we have ROTARY.
* Allow use of GPIO 0
* Another bad piece of documentation
* Fix docs and also free the timer
* Now adds a self reference to prevent GC until after close has been called and
any queued messages have been flushed.
* Simplified the code a bit
* Proof-of-concept multi-type console support via stdio
* Address crashes on linput's use of printf.
On an empty line input, a C3 with UART console would panic while attempting
to output the new Lua prompt. The backtrace shows a xQueueSemaphoreTake
with uxItemSize==0 as the panic cause, deep inside the uart driver, invoked
via vfs_uart and vfs_console layers, from printf.
Similarly, the printf for outputting a backspace/erase sequence would also
trigger a panic.
This workaround (of not mixing fflush() with printf) is likely merely hiding
a deeper issue, but it appears to be consistent. Plus, printf with no args
and a user-supplied format string is a no-no and should be fixed anyway.
* Work around IDF inconsistency with stdout buffering.
* Increase console task stack size.
Seems on Xtensa it ended up not being enough.
* Switch to single-byte console reads.
* Stop cheating and feed Lua from the right context.
* Work around IDF buffering stdout even when told not to, on ACM consoles.
* Initial build support for esp32c6.
Plus fixup of module selection for a variety of targets.
* Update github actions to node 20 versions.
* Update github build to deal with Lua 5.3 being default.
* Address fatal compiler warning.
Newer IDF toolchain is stricter, and we'd apparently failed to build test
the Lua-5.1 path for some time.
* Initial build support for esp32h2.
* Upgrade IDF to v5.1.3
* Fix left-over incorrect type in uzlib.
* Avoid null pointer crashes when debugging startup.
* Workaround for using wifi module on S2 with USB-CDC console.

* Choose the number of RMT buffers in the ws2812 module.
The number of buffers required for optimal operation should be selected
by the ws2812 module, not the caller.
* Add parameters for RGB LED bit times.
This patch adds compatibility for different RGB LEDS besides the WS2812.
ESP evaluation boards like the ESP32-C3-DevKitM-1 use an SK68XXMINI-HS
RGB LED which does not respond to the timings of this module.
The patch adds optional parameters for the bit timings to the write
function. If the new parameters are not supplied, the old values are used.
An example for the SK68XXMINI-HS is provided in the documentation.
* Remove restrictions from RTM translator.
The old RMT translator was not able to split the bits of the source
data into the size requested by the RMT transmitter. Either all 8 bits
of an input byte were translated or none.
The new routine removes the restriction by delivering exactly the
requested amount of data to the transmitter, which results in a more
balanced buffering of translated data under load.
* Add a parameter for the RGB LED reset time.
This patch introduces a new optional parameter for the reset time
in the RGB LED communication. The default is 51.2 microseconds. A
value of 0 sends no reset signal, which allows a small optimisation
for consecutive write commands.
Please note that the reset time of the old code should be 50
microseconds, as the define WS2812_DURATION_RESET suggested. Due to the
restrictions of the old RMT translator routine, it was slightly
increased to 51.2 microseconds. This patch keeps the value of 51.2
microseconds to be as compatible as possible.
* Minimize the time drift between RMT channels.
Place all RMT channels in a group to minimize the time drift between
the signals. Please note that this feature is not available on all
platforms.
* Fix the description of the SK6812 LED in the example code.
The SK6812 expects the data for the green LED first, then red and
finally blue. It should be described as a GRB LED.
Plenty of dependency adjustments, printf format specificier updates,
FreeRTOS type and macro name modernisation, not to mention API changes.
Still plenty of legacy/deprecated drivers in use which will need updating.
The following features have been removed due to no longer being available
from the IDF:
- ADC hall effect sensor reading
- Configuration of SD SPI host via sdmmc module (now must be done first
via the spimaster module)
- FAT partition selection on external SD cards; only the first FAT
partition is supported by the IDF now
On the other hand, the eth module now supports the following new chipsets:
- KSZ8001
- KSZ8021
- KSZ8031
- KSZ8051
- KSZ8061
- KSZ8091
- Possibly additional models in the LAN87xx series (the IDF docs aren't
clear on precisely which models are handled)
Further, the sdmmc module is now available on the ESP32-S3 as well.
By not relying on the internal details of the RMT registers. For example
on the esp32s2, the threshold event bits start at bit 12 not bit 24, and
on the esp32s3 the memory buffers are only 48 words not 64. Also the
esp-idf recommends against hooking the rmt ISR in the first place.
Instead, use the published rmt APIs (specifically rmt_write_sample and
rmt_translator_init) and the default rmt ISR, which should be much more
resilient against future esp32 SoC changes.
In addition to exposing additional configuration settings, it now also
provides access to the wifi station power-saving control.
Documentation updated, and wifi.sta.getconfig() has been documented. Not
sure why that wasn't already the case.
By returning result as a signed 32-bit int between INT32_MIN to IN32_MAX
which is represented the same regardless of 64-bit support or
integral-only builds.
Also updated docs, fixed links and clarified behavior of random APIs
when WiFi isn't started.
The modern spiffs backend doesn't like stat("./somefile") for something
on the root of the filesystem, and instead only accepts "somefile"
(it also doesn't like "/somefile"). The error from stat was being
ignored which is why the file sizes all appeared to be zero.
The fix is to change file.list() to pass just the filename, unless a
directory was passed to list(). Also improved error handling a bit.
Slightly reworked embed_lfs.sh to better cope with attribute size changes
in future compiler versions, without needing to be updated again.
RMT register naming changed once again...
If this variable is not set in the config it may contain random data and set the clock source to the REF_CLK
resulting in timing errors, the DHTx, DS18B20 and ws2812 devices to not communicate.
The return value from fwrite was being checked against the size of the data rather than the number of bytes written.
This caused node.compile() to falsely return failure.
