But the 2nd RX PIC receives perfectly. It's the 1st TX PIC that gives a framing error. And yet the 2nd RX gives an ACK using the HSEROUT structure, and it can DISABLE transmitter just fine.
I'll be adding several more PICs on the network later, along with a tri-state BUSY line. The BUSY line will determine which PIC will be permitted to TRANSMIT at any given time. And that's why I...
checking your stuff........ if you use interrupts (DT ints), for RX interrupts, you would not use PB hserin in the int routine. Rather get the characters in your routine and store them in the...
I'm not sure exactly what you intend to do, but TRMT gets asserted half-way into the STOP bit, so if you immediately disable the TX then the STOP bit will be half the time and generate a framing...
I would not give up on the 18877 chip. Sometimes the view seems great but has pitfalls and all you need is to sleep on this. Next day will come the aha moment!
Re: Framing error if I disable transmitter after shift register is empty?
don't give up on yourself or sell yourself short !...... it is a good project :)
