TLC5947 LED driver

Component/Hub

Adafruit's TLC5947 board

This component represents a chain of TLC5947 24-Channel, 12-Bit PWM LED Drivers, which is used e.g. on this board from Adafruit.

To use the channels of this components, you first need to setup the global tlc5947 hub and give it an id, and then define the individual output channels.

# Example configuration entry
tlc5947:
  data_pin: GPIOXX
  clock_pin: GPIOXX
  lat_pin: GPIOXX

Configuration variables

• data_pin (Required, Pin Schema): The pin connected to DIN.

• clock_pin (Required, Pin Schema): The pin connected to CLK.

• lat_pin (Required, Pin Schema): The pin connected to LAT.

• oe_pin (Optional, Pin Schema): The pin connected to /OE (BLANK).

• num_chips (Optional, int): Number of chips in the chain. Must be in range from 1 to 85. Defaults to 1.

• id (Optional, ID): The id to use for this tlc5947 component. Use this if you have multiple TLC5947 chains connected at the same time.

Output

The tlc5947 output component exposes a tlc5947 channel of a global Component/Hub as a float output.

# Individual outputs
output:
  - platform: tlc5947
    id: output_red
    channel: 0
  - platform: tlc5947
    id: output_green
    channel: 1
  - platform: tlc5947
    id: output_blue
    channel: 2

Configuration variables

• id (Required, ID): The id to use for this output component.

• channel (Required, int): Chose the channel of the TLC5947 chain of this output component.

• tlc5947_id (Optional, ID): Manually specify the ID of the TLC5947-component. Use this if you have multiple TLC5947 chains you want to use at the same time.

• All other options from Output.
