Can we use the below subroutine for checking whether the key is
realeased or not ... Not really, because reading P1 will only give you information about actual state of port line, but not, whether this is a result of a stable switch state or bouncing. You must use a debouncing scheme to reliably detect key release. Please have a look at my code again to see that the key release isn't needed to be detected with this debouncing scheme! Kai |
