How to Know What Pin is Interrupt Capable
How do you know what pin is interrupt capable?
Well, any STM32 pin is interrupt capable but you can only have one pin with the same number as an interrupt pin.
For example, on the Fly-E3-Pro, pin PB_12 is used as the chip select pin for the WiFi. That means that no other pin that ends in .12 can be used for something that requires the pin to be interrupt capable.
You can see all the pins that are currently assigned as an interrupt using M122 P200.
