Blink without the pause command

[DanPBP]

I'm using a pic 12F683 (internal oscillator) to turn on/off some lights on my R/C car...

I'm reading the output from the receiver with pulsin and then I can turn on/off the lights...

I'm using the pwm output to control the stop lights... Normally, they are 50% lit and when I hit the brakes they go 100% brightness...

Also, I want to blink two yellow LEDs as turn lights, but I cannot wait while the LEDs are blinking because I need to know if something else happens, like hitting the brakes....

So, that's why I wanted to know how to blink the LEDs without the pause command...

I think I could do something with the "ifs", but as you said Bruce, will have to recalibrate the code...

Thanks for your answers!

Daniel.

I would go with Darrel Taylors' instant interrupts with timer1. Disable interrupts before using
PULSIN. Then re-enable them after PULSIN. A few mS either way shouldn't be a big deal for
a heart-beat type LED on/off.

Hi, Daniel

the easy way with R/C signals ...

the servo signal is THE "missing timer" ... say the 1.5 ms is @ 40 Hz ( example )

if you want to blink @ 2Hz ...

just count the incoming 1.5 ms pulses and TOGGLE the led output for COUNT // 10 = 1,or 2 ... but not 0

takes very little CPU time.

hé,hé ...
