Hi. Thank you for reporting.

will be enough to just correct the addr value?

Not sure if it will be enough, but those addresses should be corrected.
Try it and let me know if still not working.

Addresses should be 0x88 and 0x89, isn't it?

Yes, the addresses should be 0x88 and 0x89

Changed in the file, but the eeprom read/write still doesn't work.

Attached are the SIM file, the asm, and the hex, so you can test.

The program simply count keypresses and display it on RB0-7 in binary. The current value of the count is stored in EEprom address 0x00.

On the simulation the eeprom is unaffected , and the execution is stuck waiting the WR flag to be cleared.

; Wait for the write to complete
btfsc EECON1,WR    ; WR bit cleared                                    <--
goto $-1                      ; no, keep waiting                                 <--
bcf EECON1,WREN  ; Yes, clear write enable bit
bcf STATUS,5             ; Set Bank 0

I saw that you fixed the 16f84 wrong EECON register. The same error is in the 16f83 file.

Sorry but I'm a little bit busy these days.
I will have a look at this problem as soon as possible.

Hi.

I found 2 more problems in configuration files:
EEIE ans EEIF bits not defined.

And more importantly, EEPROM is not defined in perif file.

With these changes your circuit is working for me: every button push, address 0 in EEPROM is incremented.

Attached corrected files.

Perfect. Tankyou
