ADS111x 16bit ADCs I2C rust driver no_std
Tested on ESP32, STM32G421, and ADS1115 Documentation
Example
Blocking
let i2c_speed = RateExtU32::kHz(100);
let i2c = I2C::new(peripherals.I2C0, io.pins.gpio19, io.pins.gpio23, i2c_speed, &mut system.peripheral_clock_control, &clocks);
let config = ADS111xConfig::default()
.mux(ads111x::InputMultiplexer::AIN0GND)
.dr(ads111x::DataRate::SPS8)
.pga(ads111x::ProgramableGainAmplifier::V4_096);
// Create a new ADS111x instance with the specified configuration
// Note: This only creates the instance, it doesn't write the configuration to the chip
let mut adc = match ADS111x::new(i2c, 0x48u8, config){
Err(e) => panic!("Error {:?}", e),
Ok(x) => x,
};
// Write the configuration to the chip's registers
// This step is necessary to apply the configuration
if let Err(e) = adc.write_config(None) {
panic!("Error {:?}", e);
}
match adc.read_single_voltage(None){
Ok(v) => println!("Val single {:.6}", v),
Err(e) => println!("Error {:?}", e),
}
Async
Add feature async
to Cargo.toml
:
[dependencies]
embedded-ads111x = { features = ["async"] }
let mut i2c = I2c::new(p.I2C1, p.PA15, p.PB7, Irqs, p.DMA1_CH6, p.DMA1_CH5, hz(100_000), Default::default());
let config = ADS111xConfig::default()
.mux(ads111x::InputMultiplexer::AIN0GND)
.dr(ads111x::DataRate::SPS8)
.pga(ads111x::ProgramableGainAmplifier::V4_096);
// Create a new ADS111x instance with the specified configuration
// Note: This only creates the instance, it doesn't write the configuration to the chip
let mut adc = match ADS111x::new(i2c, 0x48u8, config){
Err(e) => panic!("Error {:?}", e),
Ok(x) => x,
};
// Write the configuration to the chip's registers
// This step is necessary to apply the configuration
if let Err(e) = adc.write_config(None).await {
panic!("Error {:?}", e);
}
match adc.read_single_voltage(None).await {
