#135761 - short ISR Responding to: ???'s previous message |
I put a flag into my ISR and in the main loop I wrote this code
if (flag == 1){
lcd_data('1'+ counter);
counter++;
flag = 0;
}
but now I catch just 3 data. Secondly, I know my keyboard generate a serial data, and also my keyboard clock is connected to the port3.2 which is external interrupt and catch the fallign edge? I cant solve the problem... |
