Hello,
I've been using my Pi for exploration of the idea of a SoC. The only device I've ever connected the Pi to was an eight channel relay board. You've probably seen them, they're almost ubiquitous. They use the Songle relays in groups of 2, 4, 8, and 16.
I had been trying out different software arrangements, such as MyPi, iControl, pi-blaster, Cayenne, WebIOPi/Weaved, and somewhere along the line my Pi's GPIO_GCLK pin stopped responding. Eventually, I removed the wiring from the relay board end and reconnected. This time, the pin worked...sort of.
The pin generates a pulsed signal about every ten seconds that lasts two seconds. The two second interval is filled with 50% duty cycle 0.03 second on-off switches.
I have no idea where the signal is coming from but I'm beginning to suspect that the pin's function as GPIO_GCLK has something to do with the situation.
If anyone knows what is happening, or has any ideas on how to proceed, please feel free to post. All comments are appreciated.
Thank you,
Jim J
