Is it possible to convert this data into a sketch (program)? Thank you you suggested, I will read data on D0.D7 and send it to the serial port. Like I said, without knowing specifics of what you're doing, I'm going to err on the side of caution and say 'ain't gonna work.'

If you know the processor, it's memory map, it's opcodes and the like, you might be able to generate passable assembly language and gauge how feasible porting it to another processor is. Basically, whatever processor it was programmed for is the processor you're going to need. You won't be able to load it into an AVR and have it run. a GMP4) the code will only run on the 68HC11-variant that ran that ECM. I will say that if the EPROM came out of, say, an old General Motors ECM (e.g. Without knowing more about where this device came from and what you're looking to put the binary into, no one can really say how much work you're in for. Use a terminal program like Putty to save the output to a file.Īs for your plan to install this on another processor, I can't help. Read the data on D0.D7, convert it to a byte as needed and send it out the serial port. from OE# going low to data being valid - Toe - is just 50nS). The part is quick enough that you probably wouldn't need to put any sort of delays in (e.g. You then just need to sequence, starting at address 0x0000, the address, CE# and OE# pins as shown in the datasheet. You need to connect 15 address lines (A0.14), 8 data connections (D0.7) and CE# (chip enable) and OE# (output enable.)

As far as reading an EEPROM, it's not hard: Check the datasheet (e.g.
