We developed our code on a Photon. The SPI connection with a bluetooth chip worked flawlessly. For our first prototypes we decided to use the P1 chip and we use SPI1 instead of SPI. We also changed the code appropriately. The problem is, that now we don’t get any useful data anymore. We checked the connections, the hardware is not the problem.
We tried lowering the frequency, explicitely setting the SS pin (it’s pin 24), nothing worked.
Is there any difference between Photon and P1? Does the framework handle the SPI pins or do we have to handle them manually? The hardware SPI connections are set up correctly, we used the P1 pinout to connect them and checked twice.
Thanks in advance
