#77202 - matrix keyboard interfacing to 8051 |
hi guys i know all of you are yet confused with my problem
i have sorted most of the the details of my problem. i am trying to interface a 5*5 matrix keyboard with the 8051 but i am not being able to do it . i have tried three diffrent programs and i have even assembled them using the 8051 ide simulator these programs are showing no errors at all, but when i am loading it in to the 8051 and using the keyboard im not getting any response from the microcontroller please could you tell me where i could find a code for this program i need the code in assembly language thanks a lot |
