MOV A, #42H ;i think 43H is right Mehdi, Good point that. You, of course, are correct. After fixing that I am now reading 'FF' as apposed to 'EE' which makes a bit more sense. Mehdi said:
At first i am sure you must discrete lcd control pins from rtc control pins I am not fully sure what you mean by that line. Is there any chance you could please clarify. Mehdi said:
in addition when you want to reading a port you must first write 0ffh on the port I did not realise that was the case when using MOVX, but I have implemented this change. Unfortuneally there is still no difference to the output. Thanks for the help, Ray |
