• Hi Wilberforce! Thanks for the reply!

    I've saw this tutorial, and I have the setup for using 2 pins, but I ask if it's possible to do the IR Transmission by using just one pin (discarding the carrier part of 38kHz, and just outputting the signal, in the 38kHz frequency, but for the time required to represent the 0's and 1's).

    If it's impossible (due to the event loop and timing approach), I'll switch to the approach on the link that you shared, using two GPIOs and two transistors.
