pn53x-sam — PN53x SAM communication demonstration tool


pn53x-sam is a utility attempt to test a simple connection with a SAM (Secure Access Module) in several modes.

To run this utility you must have a SAM (like the NXP's P5CN072 chip) successfully connected to your PN53x chip.

Warning: the SAM inside a Touchatag/ACR122U is not hooked to the PN532 but to the intermediate controller so pn53x-sam won't work with a Touchatag/ACR122U.
