Teensy 2.0 Pin Config

Recommended Posts

Posted · Original PosterOP

I have a Teensy 2.0 and an Adafruit RFM95W module.

I have been debuging on how to use it, I've found out that I needed interrupt pins to make it work.

So for Teensy 2.0 it has 5 interrupt pins (5,6,7,8,24)

Managed to test 5,6,7,8 but it won't work on the 24

I need it to be on the 24 because pins 5, 6, 7 and 8 will be used on different sensors specifically because these are also used as SCL, SDA, TX and RX.

Also tested and made sure that pin 24 can do a digital High/Low and I see that it works

Any idea why it won't work as an interrupt pin?

Read the board/ processor documentation.  Maybe there is a configuration limitation with hardware/software interrupts.

^ what he said. Also, is the board new, or could the pin be fried?
