Okay, figured out issue #1 (above^) - although no errors returned indicating that the device I referenced was incorrect (I have 2), when I switched out my breakout board the board responded! Hurdle one, over.
Hurdle two: It turns out that I have a common ANODE RGB LED, not a common CATHODE RGB (RadioShack’s packaging for 276-0028 High Brightness Full-Color LED packaging providing no guidance whatsoever, tyvm). When I changed the 4th pin connection from GND to 3v3 the program worked well … with the exception that ledsOff() turns off the lone red led but leaves the RGB LED powered on. What’s the correct syntax for turning all three values of the RGB to 0/off for a common anode rgb?
I wired up the Web Control (Request) project and copied the code into the IDE, and both the check() and Build & Run() steps appear to work fine. When I attempt to connect via my agent URL, though, I get back ‘No HTTP Handler’ as a response. I copied the URL from my IDE, matched case (‘?led=1’ vs. ‘?LED=1’) on the parameter, but nada.
What’s the best way to troubleshoot what the issue might be?
