I posted a question the other day regarding project advice.
I'm doing a design that reads two thermocouples and powers peltier devices with a microchip pic and surrounding circuitry. I decided to use the Arduino Uno with the 2.8" TFT LCD as the interface and I have that working but it's not integrated with my peltier controller board.
My question was would it be easier to communicate to the Arduino via the usb (having never done that) or design do my own LCD right from the microchip pic (the LCD will be a distance away from the peltier controller board).
Someone answered saying they'd driven the LCD via SPI easily. Hence my question.
And using a ruler is crude. I'd rather go by a document but I can't find one.
So you don't recommend SPI? I don't see anything about doing it.
