Re: 12F683 interrupt on change improvement?

The output is pretty clean in my experience. I use my photodiode in photoconductive mode (reverse bias), which makes it faster and supposedly noisier but I haven't noticed any noise except in some...

Re: 12F683 interrupt on change improvement?

There are less complicated ways i think

__config _FOSC_EC & _WDT_OFF & _CP_OFF & _MCLRE_OFF & _PWRTE_ON & _CPD_OFF &_FCMEN_OFF &_IESO_OFF

Re: 12F683 interrupt on change improvement?

Yep, that did it! The output is now as smooth as the 16F883's output. The 16F883 used the INT_INT interrupt from the start. The GPC_INT requires the particulars you noted, and additionally it...

Re: 12F683 interrupt on change improvement?

Hi Dave,

How clean is the output from your photodiode?
I have been working on a similar setup recently using an encoder wheel and photointerrupter.
I had greater success feeding the MCU's input...

Re: 12F683 interrupt on change improvement?

I had thought - should I be using "INT_INT" instead of "GPC_INT"? It is set up using GPIO.2 as the interrupt pin, which is the dedicated INT pin per the datasheet. Can you set up an interrupt on...

12F683 interrupt on change improvement?

I have a project using three 12F683s controlled by a 16F883 master. The goal of the project is to track the RPM of 4 independant propellers on a quadcopter using an IR photodiode and emitter (i.e. a...
