I have a working prototype using custom board with an STM32H7 controlling, among other things, a 7" FTDI-EVE2-based touchscreen. I wrote all the UI code using EVE2.
I'm considering using TouchGFX to rebuild the UI and wonder about using a Riverdi screen with an embedded STM32H7.
Rather than have the Riverdi-embedded MCU be my main control MCU (I'd much rather not have my main computation going on ... within a screen's board), and so as not to change my current software too, too much either, would it be possible to have my main control MCU speak SPI to the Riverdi MCU, to tell it what parts TouchGFX-related code to run when?
If so, what would be the plan? Use the Riverdi extension header to access its SPI pins/peripheral? Does that even make sense?
If so, for testing, would I use some Riverdi eval set up or just get a screen I like and wire up a connection, breadboard-ish?
