tlc59711 12 channel LED PWM driver
python port of the c++ version by adafruit https://github.com/adafruit/Adafruit_TLC59711
Chip
Datasheet: http://www.ti.com/lit/ds/symlink/tlc59711.pdf Adafruit prototyping board: https://www.adafruit.com/product/1455
One communicates with the chip via the i2c bus by toggling clk (clock) to shift the current state (low/high) of the data pin into the ICs 16bit register.
Usage
Connect the IC to your pi using any two GPIO pins
| Name | RPi Pin | RPi GPIO | TLC59711 | Adafruit TLC59711 |
|---|---|---|---|---|
| Data | 18 | GPIO24 | SDTI | DI |
| Clock | 16 | GPIO23 | SCKI | CI |
| 3v3 | 1 | 3v3 | 3v3 | VCC |
| Ground | 6 | GND | GND | GND |
import the library and RPi.GPIO
import RPi.GPIO as GPIO
from tlc59711 import tlc59711
GPIO.setmode(GPIO.BCM)
tlc = tlc59711(23, 24)
now you can set each channel like this
tlc.SetPWM(0,0xFFFF)
this sets channel 0 to maximum brightness. The TLC supports 65536 brightness steps from 0 to 100%:
| Value | Brightness |
|---|---|
| 0xFFFF | 100% |
| 0x7FFF | 50% |
| 0x3FFF | 25% |
