NFC

Hello, I have a some problem of my nfc shield, I am using this shield with arduino uno, it works perfectly. But I need to use this shield with arduino pro mini 5v. And I couldnt use this shield with pro mini, I think I didnt make cable connection. Error message is "didnt find pn53x board"

Default config below D10 : SPI Chip Select D11 : SPI MOSI Pin D12 : SPI MISO Pin D13 : SPI Serial Clock Pin

And shield below

please help me for fix it

The wiki for that board shows the connections. Did you forget POWER and GROUND?

I made it, board says below

D10 : SPI Chip Select D11 : SPI MOSI Pin D12 : SPI MISO Pin D13 : SPI Serial Clock Pin

d10 nfc ----- d10 pro mini d11 nfc ----- d11 pro mini d12 nfc ----- d12 pro mini d13 nfc ----- d13 pro mini 5v nfc ------ 5v pro mini rst nfc ------ reset pro mini gnd nfc ----- gnd pro mini

but result is "didnt find pn53x board"

I dont know which is wrong ?

I think the problem is that you are using Pins 11, 12, and 13 on the shield and not the ICSP pins for MOSI, MISO, and SCLK. I don't think the shield has anything connected to Pins 11, 12, and 13.
