BLK_BOX_TC

ESP-IDF version v5.3.2

Firmware for the BLK_BOX Top control board for the puzzle PDE001.

Resources

All the files in the resources/ folder should be loaded onto a micro SD card placed in the BLK_BOX.

Developer Note: You can convert mp3 files to 44100Hz mono signed 16 uncompressed .wav files with the following command: ffmpeg -i input.mp3 -ac 1 -ar 44100 -sample_fmt s16 output.wav

File names must be no longer than 8 characters not including the extention File extentions must be no longer than 3 characters.

To build images, use the lvgl image converter [https://lvgl.io/tools/imageconverter]. Use v8. I have had the best luck with CF_RGB565A8.
