I am currently overseas helping a friend with a agriculture project, and he needed a fancy thermometer that displayed some other data. So I bought an Arduino kit and some (4) Sparkfun 4-digit 7 segment displays.
So, the source code for the COM-09230 SFE displays provided is for the onboard chip, not a library I need to use for the Arduino, right?
Anybody have any code to start me off? I found the link in the comments with the code that someone posted in the comments here:
http://www.arduino.cc/cgi-bin/yabb2/YaB ... 1247533060
But I was just looking to gather as much as I can to learn more about writing the code for SPI. Anybody have a reason I should serial over SPI?
I am also going to need to use 3 displays simultaneously, and at one time found some example code that switched between displays, but lost that link.
Anyway I am in learn mode, so any help is great. And yes, I am using google already and I am searching and reading, but it's a process and this is a call for help! Thanks!
