I recently purchased an Udoo Neo Extended hoping to get away from Raspberry Pi. I have an SPI screen from Adafruit (https://www.adafruit.com/products/2298) that I was using on my Raspberry Pi as the primary screen, and would like to do the same for the Udoo Neo. I was looking on your website on how to connect to SPI, but I was running to problems with pin outs. I assume I have to use ECSPI 3 because I need 2 slave selects, however I dont know what pins to use for SCK, MOSI or MISO. Then after I am able to connect it , I dont really know where to go from there. Do you guys have any ideas to make this work? Thank you.
