crosspad-doom

DOOM (via doomgeneric) running on CrossPad hardware, built on Mario Zechner's mcugdx framework. Standalone ESP-IDF firmware — separate from the main CrossPad app.

Hardware mapping (CrossPad rev2)

• Display: ILI9341 320x240 SPI — MOSI=47, SCK=14, CS=13, DC=21, RST=18 (mcugdx display, landscape).
• Backlight + input: STM32 co-processor over I2C @0x42 (SCL=11, SDA=12). See main/crosspad_stm32.c.
• WAD: data/Doom1.WAD (shareware) baked into the rofs flash partition at build time.
• Audio: disabled for now (upstream I2S pins collide with the LCD; ES8388 bring-up is a TODO).

Controls (4x4 pad grid, top-left = pad 0)

pad	action	pad	action
0	ESC (menu)	3	FIRE
1	forward	11	USE (open)
8	turn left	12	ENTER
9	back	10	turn right

Build & flash

idf.py set-target esp32s3
idf.py build
idf.py -p <PORT> flash monitor   # console is on the native USB-Serial/JTAG

Status

First milestone: render DOOM on the LCD + pad input. Audio, encoder-turn, and save-games are follow-ups.
