UART has IDLE line detection - it gets fired (and interrupt can be generated) after UART is in high (idle mode) level for at least 1 byte time. At 115200 bauds, that would be around 10us. This is our max latency. This one will trigger if DMA TC or HT wouldn't fire - in case we stop in the middle of transfer.

The detection is totally independent from the normal USART receiver. A break can be detected whenever it occurs, during Idle state or during a frame. When the receiver is enabled (RE=1 in USART_CR1), the circuit looks at the RX input for a start signal. The method for detecting start bits is the same when searching break characters or data.

The idle state of the RX/TX line is 1/high. As the start bit is 0/low, the receiver can continually monitor its RX line for a falling edge, in order to detect the start bit. Once detected, it can (due to the agreed-upon baudrate and thus the known width/duration of one UART bit) sample the state of the RX line "in the middle" of each (start.

So we're now adding idle line detection as suggested in the above thread: "A solution is to connect GPIOTE IN event to the UARTE RX pin and reset a timer when there is any activity on the pin. If the timer reaches a certain timeout, you know that there have been no data received for that time and you can flush the DMA buffer.".

1.3.3.1 Idle-Line Multiprocessor Format When UCMODEx = 01, the idle-line multiprocessor format is selected. Blocks of data are separated by an idle time on the transmit or receive lines (see Figure 1-3). An idle receive line is detected when ten or more continuous ones (marks) are received after the one or two stop bits of a character. The baud.

This occurs when the signal changes from the active-high STOP bit or bus idle condition. The receive UART resets its counters on this falling edge, expects the mid-START bit to occur after 8 clock cycles, and anticipates the midpoint of each subsequent bit to appear every 16 clock cycles thereafter. ...

The water lines that I'll be monitoring are split in 2 sections, lengthwise in the sheds. The longer shed has 4 sections, the "smaller" shed has 8. My plan is to diode OR all the Barndiuno Tx outputs into a single Mega UART Rx input, then multiplex a Mega Tx line, probably with a 74LS138. That is how I was going to poll each Barnduino.
