    MAX31865/rpi wiring question

    I just wanted to close this out. After further inspection I believe it was my poor soldering skills. On the 24 3 pad, some solder was touching the pad that I had broken the wire to, thus reconnecting it. I reheated the solder and was able to remove it. I plugged the chip in and it is working...

    MAX31865/rpi wiring question

    I received a new Max and wired it up. I am not getting random temps anymore. However, the temp is way off. It is reading 1325F. It is holding steady within a degree. When I grab the temp probe in my hand the temp starts rising and falls back when I let go. Any idea what would make the...

    Yes, I have had mine set to 430. The temp probe is brand new. Maybe I fried something on the Max. I may re-order and try again.

    MAX31865/rpi wiring question

    I did a simple program to turn on an led and figured out I had the ribbon, attaching the breakout board to the breadboard, attached backward. I fixed that and was able to get the led to turn on so I believe everything is attached to the pi correctly now. I also examined the MAX chip and ensured...

    MAX31865/rpi wiring question

    Thanks for the additional schematic and the info about the temp reading. I have double checked the wiring and everything seems to be hooked up correctly. I will try to let it sit a while. If that doesn't work I will review the work I did on the Max chip. Could be my rookie soldering skills :)

    MAX31865/rpi wiring question

    thanks, really appreciate it. Also, the reading from Craftbeerpi3 from my temp probe says 1811.42 F. I assume that is some default value and says something is not hooked up correctly? Let me know if you have any ideas about that.

    MAX31865/rpi wiring question

    Hi, thanks very much for the info. I have the inputs wired from the chip to the pi as you show. Can you explain the output? I thought the output would go to the SSR with one wire to ground (-) and the other to a GPIO pin for (+). Very new to this so any help is appreciated.
