Failed To Get Debounce Clock

unsigned char debouncedSwitch; ISR(aTimer) { // This is executed every 10 ms based // on a hardware timer generating an interrupt // The debounce code is here. It's one reccomended by a rotary encoder manufacturer for debouncing the encoder switches which are pretty "bouncy." I've used it and it works quite well. So in frustration I tried increasing the capacitor size or the resistor size. Which should even out typical bounces on a small switch. http://0pacity.com/failed-to/module-disk-power-on-failed-failed-to-start-the-virtual-machine.html

int steadystate1 = 0; int steadystate2 = 0; int steadystate3 = 0; //default is normally high int toggle = 1; while(1){ //if switch is HIGH this is true, else false if Do the inputs have protection from overcurrent? There is also a small amount of capacitance and inductance. i did a test off 100 pushes with my shitty logic analyzer on and i could not see one bounce!!!!

This would give you about 5ms time-constant on both rise and fall.

I don't have the numbers handy, so the following numbers are rough: It cost something like 20 clocks every 10 ms - that's 2K clocks per second, or a processor load

Device names in /dev/ are renamed so eMMC has mmcblk0 name (but having minor 8, mmcblk0 should start at minor 0) df output and /proc/partitions is again inconsistent Once I successfully http://0pacity.com/failed-to/failed-to-open-a-secure-terminal-session-key-exchange-failed.html U clever folk tend to forget that we stupid folk don't know the basics of how some things work.

Notice that those hysteresis curves that Lee posted show hysteresis on the scale of a few MILLIVOLTS, Big drawback is that the logic output level is not zero volts.

Or do the pins have some type of protection on them from overcurrent

Its all about Ohms law.

The graph shows that after 2ms the voltage is at 1.83v.

So I just made up a graph in excel using the formula shown below to check that after 2ms my voltage is still higher than 1.7v. I THINK that I've read (but could be very wrong) that some of the newest Mega/Tiny chips have input hysteresis, which would avoid any issues with respect to rise and fall Nov 21, 2014 Posts: 85 View posts Location: Oulu, Finland #57 Posted by andycrofts: Tue. Each falling edge of the switch bounce discharges the capacitor.

I've never met a pig I didn't like, as long as you have some salt and pepper. I need to learn so much especially pcb design. Like some cat from Japan, he could lick 'em by smiling. http://0pacity.com/failed-to/installation-failed-reason-load-on-module-failed-no-memory.html You only need to do software once, hardware you do every time.
