Hi,
I'm using the STR710fz2 processor, and two of the UART receive lines that can be configured as half-duplex UARTs. I intend to use this as a transmit UART.
First, is there a way to configure this as a TX only line, rather than half-duplex? I have RX disabled, but that doesn't seem to have helped.
The problem I'm having is that the line drifts low between bytes of data, and my peripheral can't interpret the data correctly (since the start bits are also low). It works ok if I add a pull-up resistor, but I'm wondering if I have something configured incorrectly.
Thanks, Andy
