- Pad 0-1: Blue, 2-4: Orange, 5: Red, 6: White, 7: Amber, 8-9: White
- Off state (velocity=0): dim at ~8% brightness instead of black
- On state: full brightness of assigned color
- clear_all() sets dim colors instead of off
- flash_activity: only LED 0, restores properly
- flash_sysex: saves ALL LED states, restores all properly
- heartbeat: only LED 9, only when no activity flash active
- Added sysex_saved arrays to track all LED states
- Set USB VID/PID via ESP32 core build flags (may work better than TinyUSB API)
- Heartbeat on LED 9 (amber pulse every 2s) confirms device is alive
- SysEx flashes ALL LEDs white for 200ms
- Regular MIDI flashes LED 0 white for 50ms
- Fixed note matching bug: removed channel check so notes 36-45 match
across channels 1-3 (Launchpad static/flashing/pulsing)
- Simplified LED lookup to match by note only (channel stored for mode)
- Replaced sparse palette with proper RGB gradients between key
breakpoints (Red, Orange, Yellow, Green, Cyan, Blue, Purple, Off)
FastLED has better ESP32 support and handles timing/RMT properly.
- Use CRGB array instead of Adafruit_NeoPixel
- FastLED.show() is more reliable on ESP32-S3
- probe command now tests all LEDs at max brightness
PixelStomp MUX uses:
- WS2812C LEDs: one data line via DAT (GPIO 9), NeoPixel protocol
- 74HC165 shift register: LD/CLK/DI for reading 8 button states
Changes:
- Use Adafruit NeoPixel library for LED control
- Proper 74HC165 parallel-load shift-in for buttons
- 8 switches + 8 LEDs (was incorrectly 10)
- Diagnostic commands: dump, ledtest, red, green, blue, read
- New PixelStompMux class with shift register read/write
- Read 10 buttons via DI (active LOW)
- Drive 10 LEDs via DAT (shift out + latch)
- LED startup animation uses MUX
- Switch polling reads from MUX shift register
- MUX instance shared between switch and LED drivers
- Remove TinyUSBDevice.begin() conflict with Arduino core
- Switch stub now reads GPIO with debounce (pins 1-10)
- LED stub now drives GPIO pins (pins 11-20) with startup animation
- All pins printed to console on init
