اول همین تاپیک کد راه اندازیش هست می تونید تست بگیرید.
بله ولی ارور داد.
الان میخوام از I2C استفاده کنم.
اینم عکس از پایه ها

خوب حالا تنها چیزی که تو سریال مانیتور میاد اینه که ماژول رو پیدا نکرده. از این کد استفاده کردم که تو نمونه های لایبرری بود
کد:
/**************************************************************************/
/*!
This example will attempt to connect to an ISO14443A
card or tag and retrieve some basic information about it
that can be used to determine what type of card it is.
Note that you need the baud rate to be 115200 because we need to print
out the data and read from the card at the same time!
To enable debug message, define DEBUG in PN532/PN532_debug.h
