The easiest question ever...!

[pkferrick]

I'm attempting to use the library to decode NEC-protocol transmissions. I am using an ATMega4809 on a breadboard and I have managed to compile and download Nec1Decoder, but so far it isn't working.

The question: what physical pin on the '4809 corresponds to 5U? As in: #define RECEIVE_PIN 5U

thanks, Patrick

See https://content.arduino.cc/assets/Pinout-NANOevery_latest.pdf

or is it the "U" that is confusing?

It is most certainly the U, as I see no U on either the diagrams you referenced or the DIP40 version of the chip I am using!   Are we talking about digital pin 5, as you would describe it in Arduino/mega328 terms?Tnx,PatrickSent from my Samsung Galaxy , an AT&T LTE smartphone -------- Original message --------From: Bengt Martensson notifications@github.com Date: 7/14/20 1:49 PM (GMT-05:00) To: bengtmartensson/Infrared4Arduino Infrared4Arduino@noreply.github.com Cc: pkferrick pkf.invents@gmail.com, Author author@noreply.github.com Subject: Re: [bengtmartensson/Infrared4Arduino] The easiest question ever...!   (#56) See https://content.arduino.cc/assets/Pinout-NANOevery_latest.pdf or is it the "U" that is confusing?

OK case solved. "U" is a literal suffix.

As bad as a programmer as I am, the first thing that came to my mind was 'unsigned int', believe it or not! So to be clear, I should connect the receiver to pin 5, which on the Atmega4809 (40 PDIP) is physical pin 38. I think that's where I have it, so maybe there is some other problem. I'll get it sooner or later!!!

thanks. Patrick

One other question- now I'm getting 'No decode', so apparently a signal is being received but not understood. I wanted to print the 'raw' (undecoded?) with something like decoder.printvalue (along the lines of what I've been doing with other IR libs) but that isn't an option. I am sending with protocol NEC, and I wonder if there's an important difference between that and Nec1.

See example IrReceiveSampler.ino.

Nec1 is a certain repeat pattern -- the "standard one". It is unclear what is meant by "NEC".
