MAX31865

[isuprotein]

I have two MAX31865 boards that I can’t seem to communicate with on my Pi3B+. I have connected them as indicated in https://learn.adafruit.com/adafruit-max ... duino-code. When I run “i2cdetect -y 1” I get

I have one of these with the everything soldered on and an RTD1000 connected.

The other I just have pinned to a breadboard.

I believe I have everything installed correctly but I cannot get the CIRCUITPY drive to show up. Any ideas?

You need the soldered connections for sure. Can you post a picture of the board connected to your Pi?

I thought if there are no soldered connections across the jumper, it would be setup for 4-wire, is that not correct?

I'm talking about the connections on the header end. You need to solder a header or jumpers to the board. Check this out. https://learn.adafruit.com/adafruit-max ... e#assembly

I tried it with both boards, the one that is soldered and the one in the picture with the Pi. The soldered one does not give any address with "i2cdetect -y 1" either.

I think the root problem of this is that I don't see a CIRCUITPY drive mounted when I connection the board. How do I troubleshot that issue?

[Franklin97355]

Which Circuit Playground are you connecting to and can we see those connections?

[isuprotein]

I am only connecting the MAX31865 directly to the Pi. I have two MAX31865, one soldered for a three wire sensor and one with only the header pins soldered on. I have tried both of these on two different Pis and can't get either one to show a CIRCUITPY drive.

[Franklin97355]

You won't get a CIRCUITPY drive on the Raspberry Pi as that is a drive from the Circuit Playground board which you are not using.

[isuprotein]

That makes sense, I was following the CircuityPython instructions. However, I don't see anything when I run 'i2cdetect -y 1'. How would I troubleshoot that? In the instructions (Installing CircuitPython on Raspberry Pi), I am put to the point where i2c and SPI are enabled and then tested.

When you run that code what do you get?

How can I initiate to send these back or send to you for testing?

Send a note containing a link to this page and your order number to [email protected]. They will get you a refund. You can keep the ones you have but you shouldn't buy another from us as they probably won't work any better as ours are tested before shipping.
