read/write EEPROM
-
How can I read /write an EEPROM on a PCB from my computer. Any help and or example plaese? kd
is this an existing PCB? what else does it hold? is there a micro-controller? what kinds of interfaces have been provided? and what kind of EEPROM (manufacturer, model, capacity, databus width, timing specs, ...)? or is this something you still have to design? and what is it for? :)

I only read formatted code with indentation, so please use PRE tags for code snippets.
I'm not participating in frackin' Q&A, so if you want my opinion, ask away in a real forum (or on my profile page).

It is an existing PCB, contains a PIC16C771 connected to an EEPROM (X24C04) via I2C and all connected to a IDC connector via I2C. this IDC is connected to computer via DIO48 PCI I/O card. I2C connects both, PIC & EPROM directly to computer. I need to read and write data from EEPROM which is already having existing data in it. Here I need some method to connect and R/W to EEPROM using I2C from my computer. kd

so you need: 1. software that implements I2C protocol on your interface (DIO48) 2. software that implements the specific EEPROM programming on top of (1) I've done similar things on embedded systems, long ago, and not on PC although it is perfectly doable. I'm not aware of any existing solution, although they probably exist. Try Google. For EEPROM make sure to obey the timing specifications. :)
