Programming IC2 24LC256

[Squibcakes]

Hi,

I'm trying to pre-program my IC2 eeprom using winpic800.

Apparantly this program can program IC2 devices but there is no help info on the hardware setup.

Has anyone done this before?
Cheers

What programmer are you using with winpic.

Looks like Winpic800 is a bit buggy... it works well using IC-prog -D... using my very simple 3 resistor programmer. :P

Have a great day.

I have a jdm myself, but I have used a SN7407 to buffer the signals to eliminate programing errors. Glad to see you sorted your problem.

Yo Squib,

3 resistor programmer

Is there a link to more info on this? I've spent almost $300 on 3 different programmers.

Just feel like kicking myself in the ___, for not knowing.

DT, its kinda in my head, but based loosly on my simple programmer http://www.picbasic.co.uk/forum/showthread.php?t=703 the only difference is that VPP is not connected, so infact you only need two (2) resistors and a 5 volt supply.

Here's a cut and paste from the top of my code.....

' TO PROGRAM THE 24LC256 MANUALLY USE ICPROG-D. SELECT THE AT24C256 CHIP
' CONNECT TO SERIAL PORT USING SIMPLE PROGRAMMER
' CONNECTIONS:
' PIN1:PIN4 TO GROUND
' PIN5 TO DATA (DTR via 4.7k) + (CTS)
' PIN6 TO CLOCK (RTS via 4.7k)
' PIN7 TO GROUND (FROM MAIN PCB AND SERIAL PORT GROUND)
' PIN8 TO VCC (FROM ext 5V)
