Hi guys,
I wish to communicate through UART between two pic mcu's, one of which is floating @ 230VAC.
I therefore plan to use some digital octocouplers to communicate through.
The Pic im using is the PIC16F1826 which i'm powering from 3.3v...the dsPic im trying to communicate with is 3.3v.
The Baud rate i intend on using is 9600 therefore meaning the period is 104uS.
I have a few of these octocouplers lying around and it would be handy if i could use them. **broken link removed**
Problem is im not really sure where to start - i started to make a rough circuit (picture attached) however there wasn't a square wave on the output and i wasn't receiving the right data the other end.
Thanks for your time.
