Ok, so after 10 days we have:

UiFlow - 5 MicroPython - 5 Arduino/PlatformIO - 6 M5EZ - 2 ESP-IDF - 0

I'd be interested to hear from more people. M5Stack, do you have an idea of the distribution of operating systems for the community at large?

OK it works. So for future reference this is what I did:

Turn on the unit (mine is an M5StickC with UIFlow 1.6.6 firmware) press the M5 button quickly after that to enter setup mode (my screen shows <code>) side button to get the Setup menu M5 again to select it Switch Mode M5 again side button to select APP side button to select '..' at top M5 to go back to previous menu side button to select Reboot M5 to reboot

From now on whenever you turn it on the Stick will run boot.py and then main.py in the /flash directory.

If when it's so running you attach the device to a computer via the USB cable, you can interrupt whatever it is doing by starting Thonny and hitting ctrl-F2 (Stop/Restart Backend), which will bring up the MicroPython REPL prompt. Cool.

You can always use sprites to get rid of flicker. It happens because you write to LCD in runtime which is slow. Try sprites;

First, create a sprite and set the size. Then fill it in black to avoid overwriting text.

disp_buffer = new TFT_eSprite(&M5.Lcd); disp_buffer->setSwapBytes(false); disp_buffer->createSprite(240, 135); disp_buffer->fillRect(0, 0, 240, 135, BLACK);

Then write desired text and push it to screen.

disp_buffer->drawString("This is some text", 0, 0, 2); disp_buffer->pushSprite(0, 0);

Hello Jack

you are welcome and thank you.

You'll need to check the MPU6886 datasheet

There is a sleep mode bit (Bit 6) in register 107 (power management 1). When I read that register I get 0x01 which seems to be the default. To put MPU6886 into sleep mode I'd write 0x41 into that register like that:

import i2c_bus i2c0 = i2c_bus.easyI2C(i2c_bus.PORTA, 0x68, freq=400000) i2c0.write_u8(107, 0x41)

Thanks

@mb You need to read a bit about py and c++ difference
