@ED201,
There is little point in posting a JPEG of your Nucleo board. Everyone knows what a Nucleo-F446RE looks like.
@TFTLCDCyg,
The Mcufriend Uno Shields mate directly with Nucleo64 and Nucleo144 headers.
Your NHD display contains an intelligent CPU. You just send high-level commands via SPI or otherwise.
Simple interface but you need to provide the hardware adapter board to mate with the Nucleo.
I would guess you get stunning graphics, fonts, text, ... Plotting individual pixels will be arduous.
Much like RA8875.
I have made a 40-pin SSD1963 display adapter with a BluePill and protoboard. The BluePill can do the local graphics. And receive high-level commands like your FT813.
