Hello , i have a problem with a pic18f4520 when i use with the programmer TL866A .
The trouble begin when i try to read the ic . the software get out this error message "ID error, Checked ID is 0x000 ".
And then i take off the option "Check ID device" ,i return to read the ic. At the hex dump viewer show me the rows and columns full from zeros .
The next step that i do ,it is a ic test with the option "Blank check" and show me a info message that the flash memory isn't empty and this mark all the positions that it has different values ,
when before the ic seemed that it didn't read.
Furthermore, sometimes the " id code IC "acknowledge me and it works without problem
.
Is it possible that the ic suffered a electrostatic shock when i manipulated with the nude hands? And if so why isn't the IC dead ?
