+# TM1829 Module
+
+## tm1829.writergb()
+Send RGB data in 8 bits to a TM1829 LED chain.
+
+#### Syntax
+`tm1829.writegrb(pin, string)`
+
+#### Parameters
+- `pin` any GPIO pin 0, 1, 2, ...
+- `string` payload to be sent to one or more TM1829 LEDs.
+  It should be composed from a RGB triplet per element.
+    - `R1` the first pixel's red channel (0-255)
+    - `G1` the first pixel's green channel (0-255)
+    - `B1` the first pixel's blue channel (0-255)<br />
+    ... You can connect a lot of TM1829 ...
+    - `R2`, `G2`, `B2` are the next TM1829's red, green and blue channel parameters
+
+#### Returns
+`nil`
+
+#### Example
+```lua
+r = 0
+g = 255
+b = 0
+leds_rgb = string.char(r,g,b, r,g,b) 
+tm1829.writergb(2, leds_rgb) -- turn two TM1829s to green, connected to pin 2
+```
+
+#### Example 2
+```lua
+tm1829.writergb(3, string.char(0, 0, 255):rep(20)) -- uses GPIO0 and sets twenty LEDs to blue
+```
+
+## tm1829.writebrg()
+Send BRG data in 8bits to a TM1829 chain.
+In contrast to writergb(), use TM1829s internal BRG order
+
+Usage: see tm1829.writergb()
