Hello Everyone,
I am new to Teensy 3.1 (a week actually). I am planning to interface RFM22B (from sparkfun).
Using 10:13 pins for SPI, but not sure of teensy pins suitable for Interrupt input and ShutDown for RFM22B.
..and to extend the same question a little further,
#1: is it possible to toggle all the pins on Teensy 3.1 ?
#2: what pins can be used for interrupt input ?
#3: I think I read somewhere that the Teensy 3.1 pins are 5v tolerant, can I assume all of it or few pins only ?
and lastly (not related to the pins)
#4: The VOUT33, how much load can it take ? i.e. if I were to power RFM22B off of it ..is that safe ?
Regards
Vignesh
