API

dmx_0.init_dmx(1, 1)

• Initialize the DMX module dmx_0, set it to MASTER mode, and specify the use of UART 1 for communication.

dmx_0.deinit()

• Deinitialize the DMX module dmx_0, stopping the module's operation and releasing the associated resources.

dmx_0.write_dmx_value(1, 0)

• Set the output value of DMX channel 1 to 0, with a value range of 0 to 255.

dmx_0.clear_dmx_buffer()

• Clear all DMX channel values and reset them to default values (typically 0).

dmx_0.read_dmx_value(1)

• Retrieve the current value of DMX channel 1 and display the value through print (returns the value as an integer).
