Hi, I am having problems interfacing a PN5180 (https://www.aliexpress.com/item/4001084524106.html?spm=a2g0o.order_list.order_list_main.16.12091802I4McDG) with a ESP32 (wroom-32).
Everything seems to work fine, but when I put one of the cards near the sensor nothing happens. The card or rfidtag are the ones shipped alongside the PN5180 sensor I bought online
The connections are below:
// 5V <--> 5V
// 3.3V <--> 3.3V
// GND <--> GND
// SCLK, 18 --> SCLK
// MISO, 19 <-- MISO
// MOSI, 23 --> MOSI
// SS, 5 --> NSS
// BUSY, 16 <-- BUSY
// Reset, 17 --> RST
I have also tried the below with the same outcome:
// 5V <--> 5V
// 3.3V <--> 3.3V
// GND <--> GND
// SCLK, 18 --> SCLK
// MISO, 19 <-- MISO
// MOSI, 23 --> MOSI
// SS, 16 --> NSS
// BUSY, 5 <-- BUSY
// Reset, 17 --> RST
The code is the sample code got from the PN5180 library:
#define PN5180_NSS 5
#define PN5180_BUSY 16
#define PN5180_RST 17
PN5180ISO15693 nfc(PN5180_NSS, PN5180_BUSY, PN5180_RST);
