Using Arduino Nano Every instead of Arduino Nano at an acustic levitation project

[dzsingiszke]

Hello All,
I wanted to make a fun project based on instructables acustic levitator however, I bought Arduino Nano Every instead of Arduino Nano. I'm not very well versed in coding, and when I tried adding the code in the guide:

#include <avr/io.h>
#include <avr/interrupt.h>

#define N_PORTS 1
#define N_DIVS 24

#define WAIT_LOT() __asm__ __volatile__("nop\n\t" \
                                        "nop\n\t" \

Compilation error: 'TC_CLKSEL_DIV1_gc' was not declared in this scope

Can I somehow salvage the situation with the Arduino Nano Every or should I just buy a separate Arduino Nano?

Thanks very much in advance for all your help!

Can I somehow salvage the situation with the Arduino Nano Every or should I just buy a separate Arduino Nano?

The latter will be easier.

You should be able to make this work with the Every, too. The author of the sketch quite extensively used direct register programming to get certain things done (e.g. generate a 40kHz waveform) on the ATMega328 chip used on the regular Nano. There are equivalents for these actions on the ATMega4809 used on the Every, but you'll have to root around the datasheets of both chips to 'translate' the sketch to the Every hardware. Given this:

@dzsingiszke

I'm not very well versed in coding

...I'd just get a Nano instead and get going with the project.

[dzsingiszke]

If I select that the board on Arduino IDE is the Nano, I still get very similar compile error.

It's different from the code you posted in #1. I don't know where you got that code. I got the code in my post from step 13 in the page you linked to.

@dzsingiszke

TCA0.SINGLE.CTRLA = TC_CLKSEL_DIV1_gc;

Instructions like these are not valid on the "classic" Nano, or any ATmega328-based processor. They might be for the Nano Every.

If you inform the compiler that it is to compile for the classic Nano, it will flag such errors.

[rsmls]

@jremington

They might be for the Nano Every.

Some googling suggests they might work for the XMEGA D3 series. I don't think any of those found their way onto an Arduino board, but who knows!?

@dzsingiszke did you feed the code from Instructables into ChatGPT or something? That would explain the hodgepodge you ended up with.

[dzsingiszke]

Yes, I tried asking ChatGPT if it can make it work to my Arduino Nano Every, but to no avail. Damn I forgot that so easily.
Anyway the code works, now I just need to order an Arduino Nano

[rsmls]

@dzsingiszke

Yes, I tried asking ChatGPT if it can make it work to my Arduino Nano Every, but to no avail.

No, AI has many merits, but it's not too good at making code yet. Since it has no awareness as such, "it" basically doesn't "realize" that the register mapping for an Every (Mega4809) is really different for another controller.

Artificial Intelligence is a misnomer, really. It's not really intelligent. It's just reasonably good at spotting patterns. It just can't understand/interpret these patterns.
