18F2620 Interrupt

[Ron Marcus]

Greetings all,
I was using the hardware serial receive routine from the ME website for the 18F452 with great success. When I upgrade to the 2620, it won't work. Is there some interrupt difference I am not catching?

Thanks,
Ron

Ron Marcus, I have migrated one of my projects from 18F252 to an 18F2620 and the only things I changed were the A/D configuration settings as the definitions are a bit different. I use 38.4k baud interrupt driven receive and transmit routines enabled continously. Recheck the data sheet and make sure you have all of the interrupt registers set correctly and the USART registers set correctly.

Thanks. I will look for a mistake in the code.
