Struct UartRxMonitoringDecoder

pub struct UartRxMonitoringDecoder {
    pub decoder: UartBitbangDecoder,
    /* private fields */
}

A wrapper for the UartBitbangDecoder which converts the waveform returned by the GpioMonitoring interface into the uniform discrete samples that are understood by the decoder. This performs uniform sampling according to the baud rate from the initial response and the edges provided by monitor reads, optimized to avoid sampling whilst the UART is idle.

Fields

decoder: UartBitbangDecoder

Implementations

impl UartRxMonitoringDecoder

pub fn new( decoder: UartBitbangDecoder, clock_nature: ClockNature, start: MonitoringStartResponse, ) -> Result<Self>

pub fn decode_response( &mut self, response: MonitoringReadResponse, signal_index: u8, baud_rate: u32, ) -> Result<Vec<u8>>

Decode a MonitoringReadResponse from the GpioMonitoring interface, performing uniform sampling and decoding the sampled UART output. signal_index specifies the MonitoringReadResponse signal corresponding to the UART RX pin (normally 0).

Expects at least a UART frame time of idle since the initial timestamp before it will start sampling (any malformed data is dropped).

Note: it is expected that all monitor responses since monitoring initialization are fed to the decoder through this function. If any monitoring events are lost, this could cause the corruption of some received UART data.
