I would be happy if someone could explain to me how this would work with REMOTE+ and chart data either I do not get it or it does not work

in my case all is working fine on core2 LCD module is connected over PortA

Have you updated the firmware on the colour lcd?
I get the framebuf error if I don't add the init screen block

Nope, just out of the box and go. First try with Atom lite fail but on core2 and init in the setup all looks legit.

LCD firmware update and device tested with M5StickC, ATOM, Stamp... From Arduino it works fine but from UIFlow no way.
Error from M5StickC plus is "LCD object has no attribute frame_buf

Could you post your working UIFlow?

I have the same issue, gives me the error "'Lcd' object has no attribute 'frame_buf'".

Hello @Phuturist

using UIFlow 1.9.0 works for me (well kind of). With M5Core2 I can use the whole LCD unit screen (eg. 135 x 240). However with M5Atom (or M5StickCPlus) I can only use part of it, else there is an out of memory error. Here is what works for me with M5Atom.

Thanks
Felix

Thanx Felix, it's indeed now working for a small partion of the screen when connected to my M5StickC Plus. Trying to set it to it's actual size indeed results in a memory allocation error. I had seen that one before as well but didnt think it was related to the screen size. If anyone knows how to fix the memory allocation error, please let me know.
