|
|
tm1829 is a library to handle led strips using Titan Micro tm1829
|
|
led controller.
|
|
|
|
The library uses any GPIO to bitstream the led control commands.
|
|
|
|
!!! caution
|
|
|
|
This module has an _optional_ dependency to the [pixbuf module](pixbuf.md) i.e. it can work without. However, if you compile the firmware without pixbuf the respective features will be missing from this module.
|
|
|
|
## tm1829.write()
|
|
Send data to a led strip using native chip format.
|
|
|
|
#### Syntax
|
|
`tm1829.write(data)`
|
|
|
|
#### Parameters
|
|
- `data` payload to be sent to one or more TM1829 leds. It is either
|
|
a 3-channel [pixbuf](pixbuf) (e.g., `pixbuf.TYPE_RGB`) or a string of
|
|
raw byte values to be sent.
|
|
|
|
#### Returns
|
|
`nil`
|
|
|
|
#### Example
|
|
```lua
|
|
tm1829.write(5, string.char(255,0,0,255,0,0)) -- turn the two first RGB leds to blue using GPIO 5
|
|
```
