16F84a Counting RA4 Input : output to single LEDs : comment

For the moment there are some problems in displaying comment text directly so I have re-created Justins entry here:



I don't understand. Do you want it to count the number of times you press a button and display a different LED for each press? That would be easily done with something like

unsigned short x = 0


void main () {

if (porta & (1<<4)) { // check key press
delay_ms (20); // wait for boucing
while (!porta & (1<<4)) ; //wait for release
++x
}
if x == 1 ...  //first press
if x == 2 ...  //second press
if x == 3 ...  //etc
}

Hope this helps,
Justin
