My first little project was a Temp component with the RS232 shield that told a C# Windows Form what the temp was when you clicked a button. Still working with it to have the Windows Form ask the Panda what the Temp is, or better yet figure out the interrupt stuff and have it update automatically ever so many seconds. (My overall task is to have the computer talk to FEZ via RS232).
Sorry about the absense of pics, need to get my camera fixed first
By the way, anyone has ideas of how to make a keypad? I wonder why there is no such thing in the components, it should be pretty common feature to have…
I’m thinking about making 5-10 buttons and a diode matrix, for each key to ground corresponding IO pin, and a common “onkeydown” pin with interrupt feature - one for the key block, because we have many i/o pins, but only a handful of interrupt-enabled ones.
Well, yes, but I initially thought it would be a completely headless device, with LCD only for monitoring purposes (thermometer, 10Amp relays and a “mode” switch for controlling heaters)
