Hi everyone, after more than 20 days, we are here to release a new version of the UIFlow 2.0 preview firmware, more information can be found in this thread, thank you for your feedback in the last firmware, we believe that some of them have been fixed, but also There may be new bugs introduced, I hope you can help test it again.
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.

They actually operate on the same register, this block is used to operate independent wheels, there may be some translatione problems ( use pulse less accurate ). The parameter range is -127 to +127. we will update it later, thank you feedback.
We plan to make a big optimization and change to UIFlow in 2022. At present, we have completed part of the optimization of the micropython firmware, but there is still a long way to go. Before the Chinese New Year, we released a very early version of the firmware for everyone to experience. Hope you can give us some feedback.
The currently released firmware mainly has the following features:
But this is a very early stage firmware and the following features are not yet supported:
