hello anybody
I have made my APOLLO2 programmer to program I2C memory chips ( 24C16,24C64,...) as well as FUN cards .
I have a problem with programming memory chips , the programmer can do programming and reading the chip without coming up any warning message to show any problem during operation , but the data which is read , is completely different from what is considered for writing in the chip .

Do you know the reason for this problem ?

In addition , I am 100% sure about right connection of my appoll2 and I have just tried to progam 24C16 and I use " I2C prog v 1.1 software " by Majki for this purpose .


24CXXX
pin No.--------->To

1,2,3,4-------->GND
5-------------->parallel port pin No. 6 (through a 220 Ohm resistor )
5-------------->parallel port pin No. 11
6-------------->parallel port pin No. 5
7-------------->GND
8-------------->Vcc

Thank you

Behzad
