UIFlow 2.0.1 firmware preview version
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.
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:
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
draw image example
# -*- encoding: utf-8 -*- # draw image test import m5 from m5 import lcd import random import time m5.begin() jpg = open("res/img/m5stack_80x60.jpg", "b") lcd.drawImage(jpg.read(), 0, 0) jpg.seek(0) lcd.drawJpg(jpg.read(), 0, 180) jpg.close() bmp = open("res/img/m5stack_80x60.bmp", "b") lcd.drawImage(bmp.read(), 240, 0) bmp.seek(0) lcd.drawBmp(bmp.read(), 240, 180) bmp.close() png = open("res/img/uiflow_44x44.png", "b") lcd.drawImage(png.read(), 116, 98) png.seek(0) lcd.drawPng(png.read(), 160, 98) png.close() time.sleep(1) lcd.clear(0x8BF5CE) lcd.drawImage("res/img/m5stack_80x60.bmp", 0, 0) lcd.drawImage("res/img/m5stack_80x60.jpg", 240, 0) lcd.drawImage("res/img/uiflow_44x44.png", 138, 98) lcd.drawImage("res/img/m5stack.png", 0, 0) lcd.drawBmp("res/img/m5stack_80x60.bmp", 240, 180) lcd.drawJpg("res/img/m5stack_80x60.jpg", 0, 180) time.sleep(1) lcd.clear(0x8BF5CE) lcd.drawPng("res/img/m5stack.png", 0, 0)

Which version should I download for the M5Stack Core2?
For flashing eigenet but also Thonny excellent, right?
M5Core2 has SPIRAM so I'd say try the version with SPIRAM.
I can confirm that the NOSPIRAM firmware, flashed onto M5Atom, now allows to scan for WiFi networks successfully.
on M5Tough the
m5module incorrectly exposes
btnCwhich M5Tough does not have.
import m5 help(m5) object <module 'm5'> is of type module __name__ -- m5 begin -- <function> update -- <function> BOARD -- <class ''> getBoard -- <function> btnA -- <> btnB -- <> btnC -- <> btnPWR -- <> btnEXT -- <> display -- <> lcd -- <>
