thanks for the help @felmue - ive got it working now - i think i must have been pretty tired because I have no idea how all 3 attempts failed. It works with .waspressed and by attaching a handler to events for the M5.BtnA - I have no idea what I was doing wrong all 3 times. I found one issue - it was a silly mistake in my handler logic :D but this does not explain .ispressed not working before. Maybe its something to do with a lack of sensitiviity as well - but the important thing is - they do work and I've got it working. But trying to make a button bigger all the way down to 280 does not seem to work - which is a shame becasue I have to make 2 declarations to the handler. but thats ok. Thank you

@fonix232 Thanks! For me the exercise is much more exploring how the epaper display works when drawing the different components and how to optimize partial updates. I will have a look at the projects you mentioned and see if I can find some inspiration!

Hello @Alban_T the sketch you linked is for M5Stack devices. M5Atom Lite is a bit different. For instance: I assume you modified #include <M5Stack.h> to #include <M5Atom.h>. did you also adapt the M5.begin() call to enable I2C? E.g. M5.begin(true, true, true) - the second true enables I2C on Atom Lite. is your sensor connected to the proper GPIOs? E.g. SDL - GPIO25 and SCL - GPIO21. excerpt from M5Atom.cpp as reference: void M5Atom::begin(bool SerialEnable , bool I2CEnable , bool DisplayEnable ) { if( _isInited ) return; _isInited = true; if( I2CEnable ) { Wire.begin(25,21,10000); } Hope this helps. If not, feel free to post the full sketch. Good luck. Felix

Please strictly follow the power supply voltage specifications we use. 5V

X = int("x")

My question is, if the behavior is required or an artifact of the integration with the driver? I think this is required. When actually transferring data to the screen, this is done 4 pixels at a time. Shouldn't the library simply forbid creating a canvas that is not a multiple of 4? Probably, yes.

@joja En este link puedes ver la comparativa de los pines entre el Stack y el Core2, gentileza de @felmue Saludos Carles

Adding investigation, this seems to happen only if you upload to the core2 an empty project.
