None that I know of. I'm using the Serial Communicator from MCSP+ 5.0.0.5. on the PC side.

The adapter has RX/TX labels. I connected them in relation to the PC - not the PIC.


I reconnected the whole circuit now, and it works...? I don't know why, I didn't change anything except recompiled with the HSEROUTs enabled again.

1. The only difference is that I rebooted the PC today. The only thing I can imagine is that the adapter was somehow disturbing the PIC USART even if it was only sending, there is no HSERIN code.

2. I have noticed recently that I have to shut MCSP+ down because it no longer sees INCLUDES and stuff like that (I can't remember what exactly). I would just restart MCSP= and the compile would work without errors.


I hate intermittent problems...
