I am making a plan to develop an MCU bord, on which the LittlevGL suppose to run over FreeRTOS. The board will support over 7" to 10.1" TFT LCD with a touch screen.
I consider which CPU I employ for the project; STM, Microchip, NXP, TI, or Allwinner, etc.
Which CPU do you think the best (off the top of your head)? In terms of the price-performance ratio and the development tool friendly.
