Interface "Phoenix"
Interface "Phoenix"
In order to be able to communicate with the SIM card, you need a device conjugating PC and SIM card. The most common, yet fairly simple and reliable is the "Phoenix". There are several implementations of it, but they all basically identical. The differences are only on how much more complicated scheme of the "iron". This is reflected in the stability of work, but even the most simple assembly can normally transmit and receive data.
His first "Phoenix" I made a long time (several years), others have tried to implement, and stopped at one of the schemes, which consistently has been working for quite some time.
Characterization
Sampling frequency: 3.57 MHz;
Reset map: direct;
Connection: Com Port;
Power supply: external or Com Port;
Purpose: to communicate with the SIM cards.
Assembly
I propose to build a circuit that combines the "Phoenix" and "Ludipipo". The first you already know, but the second is the programmer PIC microcontrollers. This combination successfully, if only because what you do not need two devices for their experiments will not have to change the prgrammator on the reader (or vice versa) depending on the situation. Despite the fact that the scheme combines two devices, the complexity is not great.
You need a sheet of foil PCB thickness of 1 - 1.5 mm, soldering prednadlezhnosti chloride, iron (III), and details:
