MUSCLE Towitoko Chipdrive Extern

[Richard Lang]

Hello!

I have a question to the Chipdrive Extern.

I need 3 commands to write something to a I2C-chip-cards with a
storage capacity of 2kBit.
1. step
0x7C;
0x64;
0x41;
0xA0;
0x00;
0x64;
0x40;
0xA1;
0x0F;
0x36;   /* check-sum */

2. Step
0x7E;
0x10;
0xDA;   /* check-sum */

3. Step
0x7E;
0x66;
0x6E;
(char)(addr  0x00FF);   /* Lo.addr */
0xA0;   /* (Hi.addr  1) | 0xA0 ... always 0xA0 for 2kBit */
0x01; /* page mode  */
0x0F;
strQS(0, buf, 7);   /* calculate check-sum */
(addr... 0-256 addres start to write on chipcard)


writing
0x40 | ((char)(n));   /* encoding number of bytes to write
...

My question is in step 3. What is the page mode ?
What is the Hi.addr vor Chipcards over 2kBit

Thanks for respons

Richard

MUSCLE Towitoko Chipdrive Problems

[Richard Lang]

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??

Hi!

I have a Towitoko ChipDriveExtern 4.3

When I ask (0x03;0x07) for the CardStatus, I get sometimes 0x50 back.
What does it mean?
