> Olin or Charles, please, which way should it be ??? If the data sheet doesn't convince you, then all I can say is that I've always set both TRIS bits and never had any problems. I vaguely remember a bug a few years ago with the UART on a 16C77 (?) where I didn't set both TRIS bits correctly. However, I'm not totally sure, and don't remember the exact symptoms nor exactly what did done wrong. Once I created the UART_BAUD macro and standard UART template module, I haven't had a single problem. I've recently added the UART_SETUP macro to STD.INS.ASPIC at http://www.embedinc.com/pic. This contains the assembly time logic to handle the advanced UART of devices like the 18F1320. I've also added support for the much better baud rate generator of those devices to UART_BAUD. They finally gave it a full 16 bit counter so you don't have to fart around with high/low speed baud rate generator mode anymore. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
