Power Toggle Button

Postby jefft » Tue Nov 19, 2013 2:04 pm

Hi Everyone,

I'm fairly new to the PSoC creator. I'm working with the PSoC 5LP develeopment kit. Attached to this message is my project I am working on to use a switch to turn on a LED but to also use that same switch to turn off the LED and turn on another after holding that LED for 4 seconds. I set up a design that I'm most confident will work, with a debouncer to a counter.

The issue I am having is with the main.c that I am building. If I use the debouncer sperately I can toggle the LED on and off with the switch easily, but with the counter connected I seem to lose this capability. Also i cannot seem to get the other LED to turn on after 4 seconds. PLS HELP.

Create an archive under the file menu and post so the forum
can look at your code and configuration.

You need different clocks for de-bouncer and counter. The counter clock must be (at least) twice the count frequency, enable of the counter could be set high.
You do not have any mechanism built-in to count the time.

I would suggest to:
Setup a timer generating an interrupt at 10 to 100 Hz
Debounce clock about 10 times the timer.
Check the debounced button when timer expires. React on button changes accordingly
