Hi all,

Just wondering if its possible to save data to a PIC16F84 for later viewing?

Thanks

Yeah, it has a 64 byte eeprom. So yes.

I need to write 5 bytes of data (integers) to memory. Can you suggest a line of code to do so.

Also, how do you then view the data stored in memory? I'm guessing I just have to click on "read" in the MPLAB programmer interface?

Thanks again

See the compiler manual for read_eeprom() and write_eeprom().

e.g.
unsigned int data_read;

data_read = read_eeprom(address);

Write:
write_eeprom(address, data);

Yeah you can read it with mplab's Read selection as well.
