I have one code of ZIGBEE module for 18F4620 but I have PIC18F4520 µC and I want to burn this code in 18F4520. Can it possible to do this without making change in code? Please reply urgent....
:sad:
The only real difference between the chips is the size of the program, ram and eeprom memory sizes.
Providing the 4620 code does not exceed the smaller 4520 memory then it should work fine.
Depending on your programmer the 4620 code should burn straight into the 4520, but some programmers may pick up that the code is for a 4620 and stop you, so you may have to re compile after changing the chip type to 4520.
That was actually HEX file but I can not able to load it that's why I have changed it's extension to PDF. R u able to download it or not? BTW now I'm sending ZIP file.....
That works fine, have often programed a 4620 with 4520 code.
My Pickit2 gave the expected warning message but no action needed.
The second shot shows that the program code only uses a small part of the 4520s program memory.
As long as the code does not store masses of data in eeprom or ram it should work fine, have fun
