testing gpio with node.js and onoff

Today was a pretty good day playing around with the Raspberry Pi. First thing I was able to do was fix my problem with the SDHC flash file system. That was fixed with fsck. See the updates from 16 February.

The second was to test the node.js module onoff. I ran the straightforward tests using my Parallax Propeller Professional Development Board. I flashed a few LEDs and pressed a button on the board simply wired into the Raspberry Pi’s GPIO header. You can see the run above.

One interesting issue seems to be the switch inputs (GPIO 18/pin 12). The switch inputs need debouncing, either in hardware or software.

But those are issues for another time, another experiment. Right now I’ve regained confidence in the overall board and its software. And for me that’s a very good thing.
