I received a tech brief from Microchip yesterday. They also have an appnote showing the same. Looked through it, but it has bad problems. For one, the screen updating is halted everytime you draw a pixel in the ram, as the same interface it used for the ram writing and the LCD updating…
I didn’t read ST’s appnote too closely, but they do use DMA (or not) to update the screen, so I assume they’re double-buffering.
ST also supplies the sample firmware.
What if there could be a 3.2" LCD (either B/W or color), would take 3 sockets (like a TFT screen, but not the R/G/B sockets, any X socket would do), with resistive touch, what would that be worth? What might someone be willing to pay for that?
I thought about that too, but speed would be a problem again, as it was with the Panda Touch…
Pair it with a Cortex-M0 as an “accelerator”, and speed is no longer an issue. Or a PIC. Or an AVR.
