NFC module with atmega programed in C
Account cancelled 2014-08-18 08:27:43 2295 Views1 Replies Hi
I bought 2 pieces of NFC module from df robot. I'm using regular C and avr, not arduino and cpp.
I have problem with comunication with module.
Old rfid modules with 125khz sends tag thru uart when tag in close to the antenna, there was no need to any initialization procedure, just power,gnd and uart initialization in Uc.
As I can see from sample program on site, pn532 need to initialize.
What i concluded :
Program sends values from array wake [24] to wake up device.
Sends also array tag[11] to get tag form tag :-X ?
please help

2014-08-19 20:46:28 afaik, if device is wake up, the request tag is just to read it from buffer. Eventho the device has seen it, maybe doesn't output it automatically. Have you tried this? Jose
