I have an Azure Sphere MT3620. I have a single Grove connected relay, which I’m trying to switch on and off.
The PIN function for the grove connector says GPIO / ISU2 …with pin names GPIO37_MOSI2_RTS2_SCL2 and GPIO38_MISO2_RXD2_SDA2
I cannot for the life of me find any working sample code to turn this thing on or off. I’m a noob to this platform.
I have gotten as far as using the Blink application demo, and I’m trying to incorporate this relay into the program.
I thought I could just reference GPIO 37 and 38 and set them High or Low… but that is not working for me.
HELP!?
