Have you tried using just the time only or hour and minute only blocks?

Hello @tomtom22

to you first question: it doesn't matter whether you press and hold the reset button to get the M5AtomS3 into download mode to burn firmware or let the automatic do it.

The press and hold the reset button method is available in case the automatic download mode fails. This can happen if for instance the currently running firmware has an issue causing the device to constantly reset.

I personally let the automatic download mode do its thing and only if that fails use the reset button method.

Thanks

Hello @PK_Pippin

you are correct, there is a conflict on GPIO33 which on M5Core2 is used for external I2C (SCL) and by the Lora868 module as CS.

The reason is that on the original M5Stack (core) the same two GPIOs (21/22) were used for internal and external I2C. For M5Core2 the two I2C busses have been split and the external I2C now uses GPIO32/33.

I guess one solution would be to switch to an M5Stack (core) instead of M5Core2 (core2).

Another solution might be to use the Ext Port for Core2 which gives you Port E (GPIO27/19) to use with the CardKB.

Please note: While I did check in UIFlow 1.12.5 that Port E is offered for CardKB I do not have the necessary hardware to test either of my two proposed solutions. So there might be other issues I haven't foreseen.

Thanks

@gavin67890 I think they are injection moulded ABS

Hello @hugo-reed

according to the M5AtomS3 documentation the backlight is connected to GPIO16. So setting that to LOW should turn it off. (Note: not tested)

digitalWrite(16, LOW);

Note: GPIO16 gets initialized and set to HIGH in function M5Display::begin().

Thanks

Hello @alpaka

unfortunately GPIO36 (one of the GPIOs used for Port B) is an input only GPIO. See here - section M5GO Base Pins and here - GPI: GPIO34-39 can only be set as input mode and do not have software-enabled pullup or pulldown functions.

I2C however requires one GPIO as output (SCL) and one GPIO which can be an out- or input (SDA). Therefore Port B cannot be used for I2C.

@felmue there is also a king running issue with the ENV III unit

Hello @Amedee

on M5CoreS3 the 5 V on the Groove ports needs to be enabled explicitly. See section Power Management here.

Try calling below function in setup():

M5.Axp.powerModeSet(POWER_MODE_USB_IN_BUS_OUT);

Thanks
Felix

StickC (Not Plus) reports RoverC not connected.

Look in the Discussion about the ENV III and the Core S3
