DMX Base

Example

Master

from m5stack import *
from m5ui import *
from uiflow import *
import module

import time

setScreenColor(0x222222)
dmx = module.get(module.DMX512)

dmx.dmx_init(13, 35, 12, 1)
while True:
  dmx.write_dmx_data(1, 0)
  wait(1)
  dmx.write_dmx_data(2, 0)
  wait(1)
  dmx.write_dmx_data(3, 0)
  wait(1)
  dmx.write_dmx_data(1, 255)
  wait(1)
  dmx.write_dmx_data(2, 255)
  wait(1)
  dmx.write_dmx_data(3, 255)
  wait(1)
  wait_ms(2)

Slave

from m5stack import *
from m5ui import *
from uiflow import *
import module

setScreenColor(0x222222)

dmx = module.get(module.DMX512)

dmx.dmx_init(13, 35, 12, 2)
while True:
  print((str('ch1:') + str((dmx.read_dmx_data(1)))))
  print((str('ch2:') + str((dmx.read_dmx_data(2)))))
  print((str('ch3:') + str((dmx.read_dmx_data(3)))))
  dmx.clear_dmx_buffer()
  wait_ms(2)

API

import module
dmx = module.get(module.DMX512)
dmx.dmx_init(tx, rx, en, mode)

• Initialize the DMX pin configuration and specify the operating mode (master/slave):
  • mode:
    • master:1
    • slave:2

dmx.read_dmx_data(ch)

• In slave mode, receive data from the specified channel.
  • ch:1-512

dmx.write_dmx_data(ch, 100)

• In master mode, write data to the specified channel.
  • ch:1-512

dmx.clear_dmx_buffer()

• Empty the DMX data buffer

dmx.delete_port()

• Inverse initialize DMX, release port resources
