Discussion Groups | Piclist | RE: pause?
A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.
pause? - wdavis364 - Jan 5 10:35:14 2007
F88, 20mhz, series of 4 push switches to add or subtract predetermine
values to "count". I'm thinking that I'm not going to be able to get
off the switch quick enough to keep it from adding the value more than
once. I need to pause after each activation? If so, how long?
Short program.
thanks
bill

Hi Bill,
Why not sit in a loop while the button is pressed? Then you don't care
how long the user holds the button down.

Ok, sounds good,only not sure how to keep it from adding to "count" each pass through the
loop.

RE: pause? - Alan KM6VV - Jan 5 12:04:00 2007
Hi Bill,
What you want is an auto-repeat on the buttons. Delay for say 1 second,
then repeat if the key is still held down. That's after you've debounced
the keys. Something like:
------------------------------------------------------------------------
/*
* function to filter keyswitch closures
* call at 100 mS rate!
* (KeyRep + 1) * 100 mS = rep rate
* key data has been put in KBDdata from SPI reads
* LastKey is global char. Get it after seeing
* Event flag set, then clear flag, wait for next key
*/
void FilterKbd(void)
{
static char KeyRep = 0;
static char FirstRep = 10; /* 10 * 100 mS = 1 sec 1st rep rate */
if(KBDdata != LastKey || KeyRep == FirstRep)
{
if(KBDdata != LastKey)
FirstRep = 10; /* reset 1st rep rate when key changes */
else
FirstRep = 1; /* rep faster after 1st rep */
SET_EVENT(KEYBOARD_HIT);
KeyRep = 0;
LastKey = KBDdata;
}
else
KeyRep++;
}
------------------------------------------------------------------------
SPI reads in my keypad (6 keys) data into KBDdata (100uS rate) from
interrupt. System main loop at 100mS calls this filter. SPI runs 16 bits
out, and 16 bits in. Other I/Os (trigger inputs and output commands) are
the important stuff, keys, jumpers and some LEDs are just along for the
ride!
Hope this helps.

Thanks Alan, I'll try it and see how it goes.
