This repository lists the complete source code to drive a Sharp Memory LCD with Arduino
Not an issue, but a humble request: make this library nrf52 compatible. It would mean a lot to me (any many others probably as well)!
Adafruit library is so slow probably because it's using soft SPI...
I am looking at using your library for a 400x240 Sharp display.
For horizontal resolution you have the following in file MemoryLCD.h at line 84:
#define GFX_FB_CANVAS_W ((DISP_HOR_RESOLUTION + 7) / 8)
Because you add a seven and then divide by 8, the result will always be non-integer, will it not ?
So, if I have a 400x240 display, then with your equation, (400 + 7) ÷ 8 will give 50.875, which of course will be hard to use when defining an integer based framebuffer. It would likely just be 50 in this case anyhow.
I'm not sure what the extra seven bits are used for, but have you tried with a value of eight, whereby the equation will be (400 + 8) ÷ 8, giving a result of 51.
