Hi,
Iam trying to isolate uart communication between Metering mcu and RF mcu. I tried with 2 different way.
one i used Analog Digitals Digital Isolator. There is no issue while communicating with that.
Then the other using Optocoupler PC817 it works for first few cycles and there is no communication after that.
How to fine tune the opto circuit.
Schematic attached here for reference.
With Regards,
