  1. Multiple GPIO pin activity monitored in a common interrupt handler example?

    I want to decode servo pulses on up to 8 channels using a Teensy 3.1 that are received from a RF servo receiver., I successfully implemented a solution for 4 channels using four separate ISR...

    You are correct, there is no reason to use this low of a resistance for pullups with CMOS circuits. A 100K pullup is still a bit wasteful for battery powered designs, 1 M will also work. 100K with...

    Mine are 0603.

    On my board, the resistors are 0603. I have attached a photo with a 0603 and a 0805 resistor to the right of R3 for size comparison.

    A 0R resistor is just a conductor shaped like a resistor that is intended to have no resistance. They are available in DigiKey, but if you have some soldering skills you can just solder small wires...
