CHIPSEA CS1237 ADC Driver

An embedded_hal_async driver for the CS1237 ADC.

Example Usage

use embassy_time::Delay;
use cs1237::{Cs1237, Gain, SamplesPerSecond, Channel, DEFAULT_BUS_FREQUENCY_HZ};
use cs1237::stm32::MetaPin;
use embassy_stm32::{gpio::{Output, Level, Speed}, Peripherals, peripherals};

async fn read_adc_value(p: Peripherals) {
  let clk_pin = Output::new(p.PA0, Level::Low, Speed::VeryHigh);
  let data_pin = MetaPin::new(p.PA1, p.EXTI1);

  let mut adc: Cs1237<Output<'static, peripherals::PA0>, MetaPin<'static, peripherals::PA1>, Delay, DEFAULT_BUS_FREQUENCY_HZ> = Cs1237::try_new(
    clk_pin,
    data_pin,
    Delay,
    Gain::G1,
    SamplesPerSecond::SPS10,
    Channel::Temperature
  ).await.unwrap();

  let _value = adc.read().await.unwrap();
}
