ExplorerHat Pro stopped working on reboot


#1

Im new to the Raspberry Pi and recently got a Raspberry Pi Zero W with an ExplorerHat Pro. Im using these to build a small robot, and all has been going well until this morning.

I hooked up the ExplorerHat Pro for the first time last night and it worked a dream first time for driving my gear motors in python. I shut my Pi down for the night and booted again this morning, but now nothing lights up on the ExplorerHat Pro and when I try to run my python or import the ExplorerHat I get the error message:

Warning, could not find Analog or Touch...
Please check your i2c settings!

I read through some other posts and have also tried re-enabling my i2c in raspi-config and running i2cdetect, with the results below:

root@raspberrypi:~# i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

Any ideas why it would suddenly stop working like this and what I can do?

I have found the issue - a loose solder on one of the GPIO pins - Im sure you’ve never heard THAT before :P

Haha! Perhaps one or two times ;) Glad you’re up and running though!
