RE: how to connect a m5 grey core to stick wireless
@bigpotatobrain Yes, this can be done using ESP-NOW in UIflow and I am currently working on this myself using an M5StickC and an Atom Matrix.
RE: RoverC + JoyC strange displays - Are the sticks broken ?
Icon.c is an image array and should be compiled into the file and compile time.
I am currently working on uiflow remote control code but getting a few bugs.

Thank you for your hard work.
RE: Working with jpg images
@delchi Hi, I am currently rewriting my book at the moment and about to redo the whole image section to make it easy to understand.
jpegs can most defiantly be done in UIFLOW as I have just done it.
Images must not be bigger than the screen size.
Images must be indexed.
Images must be compressed,
Images must have all non used colour data removed,
For CoreInk image must be in 1bit mode,
For M5paper images must be in 16bit grayscale,
Images must be no more than 50KB in size.
My current book version found here https://github.com/Ajb2k3/UIFlowHandbook/blob/master/UIFlowhandbook.pdf has the instructions in it.
