Building firmware

If you encounter errors while compiling the firmware,
you can use the configured firmware

Flash ready firmware

python3 -m esptool --chip esp32s3 -p /dev/tty.usbmodem11101 -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size 4MB --flash_freq 80m --erase-all 0x0 device/JC4827W543/lvgl_micropy_ESP32_GENERIC_S3-SPIRAM_OCT-4.bin

Possible errors.

When running a project from an IDE, such as PyCharm, you may see the error:

File "main.py", line 1, in <module>
File "lv_config.py", line 54, in <module>
TypeError: can't convert module to int

Ignore it and reboot the board using the rst button; everything should work.

After a long period of inactivity, the board may not work correctly.
Noise appears in the display when turned on, and rebooting won't fix this.

Solution: reboot the board while holding the boot button (rst+boot).
Then reboot the board using the rst button.
Connecting to a computer is not necessary at this point,
and you can power the board using a battery.
This may help keep the finished project running until the cause of this issue is resolved in the future.
