Changelog:

1. Fix the WIFI error caused by SPIRAM, now the firmware has been divided into two (with SPIRAM and without SPIRAM).
2. The problem of conflict between SD card and screen (not sure if it is completely fixed, we have not tested the problem yet)
3. Image display support (BMP, JPG, PNG)
4. Other known bug fixes

We believe that there are still some bugs that we have not tested yet, but there are also many missing functions, and we will update the new version as soon as possible.

It is now recommended that you help us develop and test firmware using:

Thonny (highly recommended)
Putty (command line)
Pymakr (VS code plugin, from pycom)

How to write firmware:

Please download the firmware with SPIRAM or firmware without SPIRAM, use esptool or Flash Download Tools to write the firmware at offset 0x1000.

esptool.py --chip esp32 --port /dev/ttyUSBx --baud 1500000 write_flash 0x1000 uiflow-c8e825d-dirty-NOSPIRAM-4MB.bin # or uiflow-c8e825d-dirty-SPIRAM-4MB.bin
