Error in IR example for CPX

[bradanlane]

In the learning guide for the Circuit Playground Express, IR CPX to CPX example, the code has the following:

encoder = adafruit_irremote.GenericTransmit(header=[9500, 4500], one=[550, 550], zero=[550, 1700], trail=0)

However, the sample code from adafruilt_irremote.py has the following:

encoder = adafruit_irremote.GenericTransmit(header=[9000, 4500], one=[560, 1700], zero=[560, 560], trail=560)

The CPX example results in the receive data being the 1s compliment of the send data.

Could you submit a PR for this? Thanks. That would be the easiest way to make sure it's corrected properly.

OK, I forked the learning guides and went to make the change and found the same error in four different guides.

This has caused me to be concerned. I can only assume one of three possible situations:

1. those guides were not tested (seems unlikely)
2. those guides somehow work but only with themselves (i.e. they somehow have the reciprocal error of the receive ... but I could not find that to be the case)
3. something has changed since those guides were written (most are 2+ years old)

I am happy to submit the pull request but I would like another set of eyes to scrutinize the changed code. I do not have a Circuit Playground Express on hand and do not have the irRobotControl board(s).

I performed my testing using a Raspberry Pi PICO and the Adafruit IR Receiver board and IR Emitter board.
