I have a COG LCD with part number ''NHD-C12864A1Z-FSB-FBW-HTT" and SPI interface with driver ST7565P. I displayed images and characters by page control.
My problem is i cant set single pixel in the display. that is first i set one pixel in (x,y) position after that i tried to set in (x1,y1).
at that time the (x,y) pixel is shifted to (x,y1). and (x.y) position is cleared .
any one know what is the issue. any commands error or my code error.
Anyway, you should not use pixel by pixed drawing. All display drivers realising two simple functions - define the window and put the data. Same in linux framebuffer, same everywhere.
