Using weak pullups on port B of 16f1936. A button to ground will cause an interrupt on IOCBN.
Question: should I use a low value resistor in line with this pull down button?
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...
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...
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...
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...
