Other Parts Discussed in Thread: MSP430FE425

hi,

we are using MSP430FE425 for Single Phase E-Meter.

we are facing a problem with optical interface,we are unable to receive & transmit the data through Optical.

Is any driver required to drive the optocoupler ? or any pull-up is required? Please specify the range.

we are using 180 ohm pull-up register  for transmitting ,1.5K ohm pull-up register  for receiving .

 

Thanks & Regards,

Rafi
