Demo

This boots the actual firmware image on esp32sim, an ESP32 emulator compiled to WebAssembly. The SD card holds Walden, the user guide, and the bundled apps with a small sample of Wikipedia (43 articles, CC BY-SA 4.0); whatever you change is gone when you reload.

Firmware

Run your own build…

Choose or drop an X4 Pro image: firmware.bin from pio run -e x4pro, or a merged firmware.factory.bin. It is read in this tab, never uploaded. An app image boots with this site's bootloader and partition table.

Tap the screen to touch it. The left and right keys turn pages, the key above the right one is Power (hold it), the round pad is Home, and the small key on top is Reset, which restarts the firmware with a fresh card. On a keyboard: ← →, H for Home and P for Power.
