#102177 - debounce switch Responding to: ???'s previous message |
where do you do debounce the key?
How often is your ISR executed during one keypress? How long does it take to transmit "printf ("Channel '%d' voltage is %ldmV\n",i, voltage);"? I am no expert, but I think due to the fact that there is no debouncing, your ISR is executed a number of times when the key is pressed only once. Your counter probably increments beyond 5, and before the end of the transmission of your first string. If I am wrong then I leave it up to the pro's to correct me... rgds Patrick |
