Hello,
I am using a SP XBEE Arduino Shield and SoftwareSerial to gather race car telemetry. It works great. I just changed from the UNO to the Teensy 3.2 using the SP Teensy Arduino Shield Adapter and it also works fine as long as I use SoftwareSerial. I want to take advantage of the hardware UART and interrupts on Teensy. But I cannot find the documentation that shows how.
hope you can help.
Thanks
