I am the manufacturer of this display, GEVINO TFT, arduino compatible, with integrated PLC functions.
I cannot post the linK due the forum restriction.
I would like to put lvgl but I am afraid it is too slow.
My display has a lot of pixels and the communication is SPI 12Mhz
The controller has a very high speed in creating primitives, characters and picture, from DMA flash chip .
However, the writing of the single pixel is slow.
1024x600 = 0.6 Mpixel
For each pixel need to send 6 byte = 3.6 Mbyte on SPI
At 12Mhz of SPI is 3.3Hz = 300mS
Can you suggest me whether to try, would it be profitable or it will be too slow anyway?
