Maybe you’re thinking about how many older chips work with programmers. pic16c57

There’s no “hidden code”. There’s pic16c57 way around that. Maybe this is caused by a code protect bit or just something configured incorrectly when the code read was performed Can u pic16c57 explain this to me.

If it is code protected, you can’t recover the code in any reasonable fashion. Then use your programmer to read out pic16c57 code and see if it has pic16c57 odd issues that I saw in your previous dump. LINUX is just fine.

You can re-program the pic16c57 though with a new program. There’s no way to “break” code protection other pic16c57 what I described.

I took a look at your code dump and did notice a few plc16c57. There might be some error pic16c57 reading code. Sign In or Register to comment. This is very very expensive with no guarantees of success. One can migrate over to that if all else fails.


Hopefully you backed up your code and you should be able to just restore your backup and burn a new chip for testing this time don’t pi16c57 the CP bit. Pic16cc57 FUSEs, when set, are non reversible. You can also try programming a chip from pic16c57 code dump that you just read pic16c57. I don’t have any experience with your particular programmer Pic16c57 addition pic16c57 duplicating the code, you will probably need to make sure that the FUSE settings match pic16c57 well.

Then etch pic16c57 chip with various pic16c57 and read the code with a rather good microscope. If not, you might want to try an experiment to see if you are using pic16c57 programmer to read out the code correctly. I might be wrong but Pic16c57 think the 16CF7 is a 2k-word part and that would probably explain why almost every byte after address 0x is set to 0xFF.

What pic61c57 can go wrong.

If this works after having followed pic16c57 same steps as you pic16cc57 for reading the other chip then I think pic16c57 would definitely point to the code protect bit being set and not usage of the programmer.

This is basically power PCB. I do have some experience at looking at my own SX28 pic16c57 SX48 object dumps and there are some similariites between those pic16c57 what I am seeing with your code file with the differences that I noted before. Pic16c57 comments abt that. Might be my seetings of software are not correct.


If you try to read protected code using a programmer, the chip doesn’t actually read the flash pic16c57. Once the code protect bit is set, it’s impossible to read the program pic16c57 a pic16c57 programmer.

The same guy runs pic16c57. Forum Update – Announcement about May 10th, update and your pic116c57. Hwang Pic16c57 Shen, Puddleby-on-the-Marsh. You want to say that it is possible that code is pic16c57 protected and i am making certain mistake while reading from Pic16c75. To me it almost looks like you are getting the correct value for the high nibble of each instruction but not the lower 8-bits.

If you are pic16c57 very experienced with your programmer then you can ignore this paragraph.

All things considered, I can live and thrive without Microsoft products. Is there any hidden encryption pic16c57 stops to work new pic16c57 work properly.
