impl DmaUartC

source

pub fn tx(&self, txd: &[u8], size: &mut XwSz, to: XwTm) -> XwEr

配置DMA通道发送数据

§参数说明
  • txd: 待发送的数据的缓冲区
  • size: 传输的大小
    • (I) 作为输入时，表示期望发送的数据的大小（单位：字节）
    • (O) 作为输出时，返回实际发送的数据大小
  • to: 期望唤醒的时间点
§错误码
source

pub fn putc(&self, byte: u8, to: XwTm) -> XwEr

发送一字节数据数据（非DMA模式）

§参数说明
  • byte: 待发送的字节
  • to: 期望唤醒的时间点
§错误码
source

pub fn rx(&self, rxd: &mut [u8], size: &mut XwSz, to: XwTm) -> XwEr

从接收队列中获取数据

§参数说明
  • rxd: 接收数据的缓冲区
  • size: 传输的大小
    • (I) 作为输入时，表示缓冲区大小（单位：字节）
    • (O) 作为输出时，返回实际读取的数据大小
  • to: 期望唤醒的时间点
§错误码
source

pub fn try_rx(&self, rxd: &mut [u8], size: &mut XwSz) -> XwEr
