Hello all I am hope that someone one here can help me out. I have a Swan 3.0 on a Notecarrier-F that is connected to a pressure transducer. That is monitoring the level of a fluid in a remote storage tank. That part works great. I then needed to add a display to the unit at the storage tank. I got an Adafruit TFT 3.5" V2 that communicates with SPI. I wrote the code for the display and got it all where it was at least functional. The issue that I have run into when I married the code is that the Swan will only communicated with which ever part it is stacked on, and will not communicate with the other component. I then disassembled everything and hooked it all up with dupont connectors and nothing. Stack it on the display and the display works. Stack it on the Notecarrier-F and the notecard works. I am at a loss and not even sure where to go from here. I have all the pins mapped, and I do not have any pin overlap. I have plenty of power 5v @ 750 mA with a peak of 400 mA with the display, notecard and sensor. It has to be a code issue that I just don’t know enough about to catch.
Hi @adpeyton and welcome to the Blues community!
I’m not sure if this will be helpful or not, but some time ago I integrated a TFT display with a Swan over SPI. Lots of wiring, but it’s documented as part of this project on Hackster.
Assuming that doesn’t help you - feel free to post your code and pictures of your hardware so we can take a look to see if anything looks off.
Thanks,
Rob
