Hello,
I’m trying to get a PN5180 to work but I seem to be missing something …
It’s 3.3v, so I’m experimenting with the ESP32 board to avoid the logic converters.
Anyone managed to make it work or has a code they’d be willing to share?
Thanks,
X
dam, i was hoping someone had been able to get one up and running …
Will have to revert back to pn532 for my projects.
I’ve ordered some PN5180, but due to Chinese newyear’s it’s going to be a while. I’ll let you know when I have some code to share.
That would be awesome!
I’ve spent a few weeks trying to get them to run, but I don’t have anything …
Just popped in my head … Maybe I have a DOA board … But I would point finger to the code first …
I found some notes online about having to set some undocumented settings. But I can’t remember where. I will see if I can find them again.
Thanks all for looking out, I can do hardware all day long, but software always been my week point …
Starting to dig into the ESP32 and realizing it’s an awesome platform! It’s probably gonna get a permanent spot on the bench.
Are you using spi? you man need to fiddle with the clock rate like the pn532.

I’m not sure how to do that …
(I did said I suck at programming right? 
)
I need to try it again and post in more details what I do and how it doesn’t work …

Are you using SPI?
What library are you using?

Spi on the ESP32.
I tried 2 codes from GitHub with no luck.
Both seam to call out the same (installed) library called “PN5180.h”
The one I got the farthest has “andras trappmann” in the header of the code …
In pn5180.cpp
PN5180_SPI_SETTINGS = SPISettings(7000000, MSBFIRST, SPI_MODE0);
Try adjusting 7000000 to a smaller number try taking a 0 off it.

Ok, found it 
Can I edit it with note++?
I’ll give it a go and see if it works
Well … I got 1 step further, the setup portion of the program seem to run through, the serial monitor said it’s started up properly
But I’m still not reading anything 
I’ll try an idea tomorrow but I’m not too hopeful it will work …
PS: it’s not even reading the board, I can’t get the product version to talk back to me 
Got my PN5180 today, and man, this board is impressive. Range is not even in the same ballpark as any other tested. And I have now tested quite a few. Best so far is about 0.5 cm from antenna to my implanted NExT.
This board can read my NExt at 2 cm! Didn’t even know it was possible, must be some radioactive stuff in this one. So far I’ve only tested using some stupid example code and reading UID. I suspect range will drop a bit reading NDEF and such, but it will be a fun challenge porting my keyboard wedge to this board.

Hi, I was having the same issue as well. I googled quite some time and found a method that will prompt response on your arduino serial monitor. Try to connect both 5v and 3v pin header at 3.3v
Where’s everyone buying theirs from? I could only find one on amazon, but I don’t know if I trust it. Found a bigger one on digikey, but it’s super big and bulky. Don’t think it’s the one everyone’s getting
Sounds awesome!
Do you have sample code and wiring diagram (or pic)?
I spent so much time trying to get it to work … I’d love to see how you made it
Got mine on Amazon … Seemed as good as any …
Amazon has burned me a few times when buying Arduino related stuff. Got a fake PN532 from them. So I’m a little wary nowadays haha
Test setup is not much to look at:
Remember that even though the library says 5v is not needed on ESP32, at least mine will not power the antenna without it.
Test code I found is even worse, but it reads UID:

Ok, been messing with this for a few days and im not getting much closer …
I now get this message in a loop (fast) and cant figure out where it comes from …
and it doesnt seam to change when i present a tag …
