DMX512 Integration for LED System

Project: Add DMX512 output to existing MicroPython LED animation system
Modify existing code

Current System:

Pyboard v1.0 running MicroPython

Controls 24 channels of PWM (8 RGB LEDs) via custom pwm.py library

Reads animation sequences from s.txt file

Uses main.py to parse sequences and output PWM to GPIO pins

Required Enhancement:

Add parallel DMX512 output via WPM432 module on pin X2

Send the same 24 PWM channels as DMX data (scale 0-100 to 0-255)

Maintain existing LED animation functionality unchanged

DMX should update at least every 100ms and after each animation step

Key Files:

main.py - Main animation controller (needs DMX integration)

pwm.py - PWM library (needs last-value tracking)

boot.py - Simple boot loader

s.txt - Animation sequences

Technical Requirements:

Use Pyboard's UART2 (pin X2) at 250k baud, 8N2 format

DMX packets: start code 0 + 24 channel values

Must send DMX break (88µs low) before each packet

PWM values stored in pwm.py class need to be accessible for DMX

Issue: Current implementation fails to output DMX despite correct UART configuration.

Deliverable: Working code that outputs both PWM to LEDs and DMX to WPM432 simultaneously.
