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

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? —You are receiving this because you authored the thread.Reply to this email directly, view it on GitHub, or unsubscribe.

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. Patrick

See example IrReceiveSampler.ino.

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