I'm building another 'tester' so I have a few questions to make sure I'm off on the right path before I get too deep. I've chosen the T3.5 as it is 5v tolerant and has a lot of I/O's to control all aspects of my fixture. After my last 'quick and easy' with Arduino Pro Mini's, I'm ready to swear them off for good as they are woefully lacking in program space.
For this project I'm planning on using Serial 4, 5 & 6 due to ease of wiring access. Are they use able by starting out with SerialBegin4? Is it OK to skip 1 & 2?
I'm also planning on using an RA8875 based display. I've read about its mis-behavin data output. For simplicity I was wondering if it really has to be used? I'm not planning on doing screen reads nor am I using the additional GPIO ports or SD Card access. I am also under the impression that the available touch screen controllers either resistive or capacitive would behave well on the SPI bus. Do they use their own controller? Since I've never used them in a design, which works better?
Thanks a bunch.
