ash c02121cd09 Add pre-build script to patch core's pins_arduino.h with Launchpad X VID/PID 
- pre_build.py patches framework-arduinoespressif32/variants/esp32s3_devkitc/pins_arduino.h
- Replaces USB_VID 0x303a -> 0x1235, USB_PID 0x1001 -> 0x0103
- Adds USB_MANUFACTURER/PRODUCT

ash 109106f1f1 Add custom pins_arduino.h variant with Launchpad X VID/PID 
- variants/esp32s3/pins_arduino.h overrides USB_VID/USB_PID
- Included via -I in build_flags before core variant
- This should force USB descriptors at hardware level
 2026-06-25 22:03:15 +00:00
ash 75f583b3c4 Revert to standard board, try VID/PID via board_build.arduino.vid/pid 2026-06-25 10:57:12 +00:00
ash b380133b3e Add custom board definition with Launchpad X VID/PID (0x1235/0x0103) 
- boards/launchpad_x_variant.json defines custom board
- platformio.ini uses custom board
- Board sets VID/PID at hardware level

ash 25713707aa Revert to working USB mode (ARDUINO_USB_MODE=0 + CDC) 2026-06-25 08:20:19 +00:00
ash 7558082e7b Try ARDUINO_USB_MODE=2 (native MIDI only) 
Disable CDC, use ESP32 core native USB MIDI stack

ash 0d738a6e5e Fix compilation: add flash_sysex to interface + remove conflicting build flags 2026-06-25 07:40:10 +00:00
ash 399c4341ed Add VID/PID to build flags for ESP32 core + stronger visual indicators 
- 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

ash 9ea09d52fe Add extra_script.py to pass -Wl,--allow-multiple-definition to linker for duplicate TinyUSB symbol fix 2026-06-23 23:18:34 +00:00
ash dbb66e1e77 Fix duplicate TinyUSB symbols: add lib_archive=no (prevents Adafruit library archiving, changes link order so local .o defines symbols before libarduino_tinyusb.a) 2026-06-23 23:14:51 +00:00
ash c737849a96 Fix build: add Adafruit_TinyUSB.h include in main.cpp, add build_unflags to prevent ARDUINO_USB_MODE redefinition warning 2026-06-23 23:12:42 +00:00
ash a3e86d0ddf Fix USB MIDI enumeration: switch from ARDUINO_USB_MODE=1 to 0 (matches working Adafruit TinyUSB example), add explicit TinyUSBDevice.begin(0) and detach/attach re-enumeration, remove conflicting tusb_config.h 2026-06-23 23:10:20 +00:00
ash be36ba9bf4 Remove broken I2S define, revert to default RMT + correct pin 12 2026-06-23 22:37:03 +00:00
ash 2b689f3b18 Move FASTLED_USES_ESP32S3_I2S to build_flags so FastLED .cpp files compile with it 2026-06-23 22:32:31 +00:00
ash bec8025f0a Add rawled bit-bang command, restore FastLED 2026-06-23 14:39:46 +00:00
ash 5f2ad9ef91 Switch from FastLED to Adafruit NeoPixel (more reliable on ESP32-S3 RMT) 2026-06-23 14:32:19 +00:00
ash 5de4de4f1a Switch from NeoPixel to FastLED for ESP32-S3 LED reliability 
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

ash 07e5cd8994 Rewrite MUX: WS2812C LEDs (NeoPixel) + 74HC165 buttons 
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

ash c94be67384 Fix for ESP32-S3-WROOM-1: safe GPIO pins, serial flush, delays 
- Switch pins: 2-7, 15-18 (avoids USB 19/20, PSRAM 26-32, JTAG 34-37)
- LED pins: 38-42, 45-48, 21 (high GPIOs, no special functions)
- Add Serial.flush() after init messages
- Increase startup delays for reliable serial output
- Board: esp32-s3-devkitc-1-n16r8

ash 9078001404 Convert to PlatformIO/Arduino format 
- Replace ESP-IDF structure with PlatformIO (platformio.ini)
- Move source files to src/ and include/
- Move libraries to lib/ directory
- Replace FreeRTOS with Arduino task/vTaskDelay
- Use Arduino MIDI library instead of raw TinyUSB
- Dual-core: MIDI on core 0, controller on core 1
