Quick question: On a 4-color ePaper display, is the nibble-packed format expected by pushImage—using the indices 0x0 / 0x6 / 0xB / 0xF—some kind of standard, or is it an internal convention of Seeed_GFX?
Also, besides SenseCraft HMI (which works perfectly), is there any other tool you recommend to generate the required image arrays?
Thankfully,
Ernesto.
