Hi all!
First: What I Do:
I am working on a entrance control project.
A ChipDrive is at the door. All People have there Chipcards, and are
registered in a database. In the database are listed the rights to go in
a special room or not. If everything is OK, the person can go in the
room. My job is the comunication with the ChipDrive. It reads the data
from the Card, looks in the Database, and open the door or not. I am
working under linux (unix).
My Problem:
With the Chipdrive Extern 2.0 (Towitiko) everything is OK.
When I use the ChipDrive Extern 4.3 I have some Problems.
I get a wrong cardStatus sometimes.
I flush the serialport, befor I send the command (0x03; 0x07)
The response is most (0x00, 0x80, 0x40 or 0xC0), but sometimes it is 0x50,
or something else ( not 0x20).
I thought the problem is in my source, so I used towitoko.c, serial.c, ...
from Carlos Prados.
There I get sometimes false from Towitoko_GetRdrStatus(BYTE* result) back.
But ONLY with the ChipDrive Extern 4.3.
Can anybody help me??
