Question asked by Joshua Snow on Mar 6, 2018

Hi forum,

How could i transmit data using a optocoupler? Is it possible?


(How Optocoupler Works and the Optocoupler Basics:


I really need to use it because I cannot disable the interrupts of PIC18F4620. I want to try something like this:

Is PC817 fast enough to do it? If not, do you have any other suggestion please?



Many thanks,
