I was wondering i anyone knew if there's a way to send less bits to the display to increase spi transfer speeds.
the ST7796s has an idle mode the supports 8 colors, but the controller seems to still expect atleast 16bit of color data from the mcu over spi. i just need 8 colors for my project so it would be nice to just use 3bit transfers to get better frame rate/performance.
The ili9488 seem to have a special mode for 3bit spi transfers but the st7796 does not seem to have anything similar. and i cant a find a screen with the ili9488 controller that fits my project...
