Programming ST Microelectronics chips?

[Charles Linquis]

You are serious - right?

First and foremost, The part you are talking about is NOT a micro of ANY kind, it is EPROM, Eraseable Programable Read Only Memory. So it must be containing code for another Micro in the system. You will need to identify THAT part to start getting close to reading or creating code for it. If it is not a PIC, PBP will not help you for that.

You can set up a circuit to read the contents and program the EPROM using a PIC. For this PBP will be of great value. Please understand you are going to get all HEX from the EPROM. Then you will need to translate that to ASM, using instruction set for the un-identified micro in the system.

This is a pretty huge job, so whatever you are wanting to modify, needs to be worth it to you. You will be able to get help here for the PIC side of things, but the rest will be up to you.

Thanks CNC

There is a PIC that most likely has the code on the board. I didn't realize that would be the key component. I'll grab that and get going. I thnk I will be able to translate it into ASM since I know the person who designed the system it came from.
