No hope, unless you can find somoni/somewhere where it has been included in the list.Is there is no hope to read it by pickit 2
Thanks for reply
Thank you for helpThere is an extended Pickit2 program called PicKitminus. It has the 12F519 in its "base" devices.
The regular Pickit2 software (V2.61) also has the 12F519 in its standard supported list (look under Baseline devices)
Now remember that running the OSCCAL will wipe out the code in the device, and you have to program it after doing the OSCCAL setup.
Now, if code protect in on for an existing chip, you will not be able to read it and thus you cannot run the OSCCAL routine without losing all programming on that chip.
