AFE4404 Rust驱动器

这是一个为Rust嵌入式-hal提供的AFE4404驱动器。它允许与AFE进行高级交互。

用法

初始化AFE

let mut frontend = AFE4404::with_three_leds(i2c, 0x58u8, Frequency::new::<megahertz>(4.0));

设置LED电流

frontend
    .set_leds_current(&LedCurrentConfiguration::<ThreeLedsMode>::new(
        ElectricCurrent::new::<milliampere>(60.0),
        ElectricCurrent::new::<milliampere>(10.0),
        ElectricCurrent::new::<milliampere>(10.0),
    ))
    .expect("Cannot set leds current");

设置TIA电阻

frontend
    .set_tia_resistors(&ResistorConfiguration::<ThreeLedsMode>::new(
        ElectricalResistance::new::<kiloohm>(250.0),
        ElectricalResistance::new::<kiloohm>(100.0),
    ))
    .expect("Cannot set tia resistors");

设置时钟源

frontend
    .set_clock_source(ClockConfiguration::Internal)
    .expect("Cannot set clock source");

读取采样值

let sample = frontend.read();
