So…nothing. Board is connected and powered using the proper stock power supply. Connected to the pi via the supplied I2C cable. At first I was connected to the “I2C OUT” on the board and that didn’t work. Then I tried the “I2C IN” with the same result. Red light is on on the board. Is it possible I have a bad board? It’s new out of the box. Thanks!
Just throwing this out there…could it be my i2cshield? I purchased the shield for the RPi Zero. However, being a N00B, I didn’t realize until I tried to hook it up that my zero w had no i2C prongs, so I tried it on a Pi 3 instead. I have ordered the I2C shield for the 3, but that won’t be here for a bit. Wondering what the difference is for the zero/3 shields??
Now I think I may have had the connector on backwards (they’re orientation independent, who knew!) Pin 1 is marked on the shield, and I looked up the pi orientation. Now that I think I have it on the proper way, still nothing. The pic is using the I2C “Out” port, but I also tried the “in” with negative results…I hope I didn’t fry something .
Right now only the zero, which has no pins on the GPIO ports, so I can’t figure out how to connect the I2C shield to it (even though the shield was designed for a zero…?). Anyhow, I’ll try that other shield (designed for the 3) once it arrives; if that doesn’t do it, I’ll pick up another 3 and try that. Still afraid I fried something by putting the shield on backwards. But I can find no mention of this anywhere on the interwebs, and you wouldn’t think I’d have been the first maroon to ever do that…
It’s showing up! Thanks for your help! Gonna try the original RP3 to see if it’s the unmatched interface board or if I fried my original RP3. Thanks again!
p.s. Before I forget, since you’re with the company: The original interface board I bought is supposedly for a Zero. But my zero has no GPIO prongs! Is that a function of my specific Zero, or is there something else I need to connect the interface to a zero? Thanks again!
