Hey Martin,
Can I please peck your head hopefully one last time?
Sure.
We're so close, got the hardware for the installation up and running, box made etc etc.
Could you have a once-over of our code: Still only seeing one sensor though all of our multimeter testing says sensor 2 is fine and ready to go. I think it has to be a code problem in the C file but I just_can't-see-it!!
You need to show me your code... The file I sent was to read two sensors. The second was the 1X8 sensor so it reads a different number of bytes. You have to change that, everything else should be the same..
Keep wondering if there's a way of being able to test the 2nd sensor in a similar vein to sensor 1 with 'i2cdetect', like if we could shift the IC switcher so it would allow us to run the test on the 2nd one.
Yes, just connect the A select line of the 4051 (pin 11) directly to 3.3V or ground to select one or the other. But disconnect the GPIO pin when you do that.
Pd is receiving on both sends (44l & 44l2) but all we have is one sensors readings - same in the prints from the C file.
Sounds like the multiplexer isn't working right. Do you have a photo of your setup? Can you confirm that the GPIO pin switches?
