Hi, I been playing with the photon maker kit for about a week. I am trying to design a systems that have 5 output, 5 input, i2c temp sensor(d1,d0) and 2.2" spi tft lcd using adafruit_ili9341. According to the docs, the photon have 16 usable GPIO, included WKP and DAC. 5out+5in+2tsensor = 12 pin ta…

Min Pin requirment for 2.2" spi TFT LCD for photon for limit pin design?

@ScruffR. I rule the RX &TX out because of this Can the RX and TX pins be used as GPIO? messages. If I used RX&TX as GPIO it may cause more trouble then I want.
