Accessing the smartcard in C

Here a simple example about how to get access to a smartcard by using the C language. We provide a ready-to-use program on our GitHub site, so just clone it with:

and then copy pcsc_demo file into your Cosino:

Now go to the /opt directory and execute:

You can obtain the sources on our GitHub site, just cloning the peripherals repository as follow:

and then, inside your Cosino, compile the code with:

warning Note: you can freely use the above commands only if you are using the microSD on Cosino’s e-shop, otherwise you need to install the compiling tools (gccmakegitlibpcsclite-dev, etc.) into your microSD.

Accessing the reader in Python

Python testing program is on our GitHub site. Clone it with:

and then, inside your Cosino, execute it with:

Note: as above, you can freely use the above commands only if you are using the microSD on Cosino’s e-shop, otherwise you need to install Python tools (pythonpython-pyscard, etc.) into your microSD.
