Module lsm303agr

Source
Expand description

SyscallDriver for the LSM303AGR 3D accelerometer and 3D magnetometer sensor.

May be used with NineDof and Temperature

I2C Interface

https://www.st.com/en/mems-and-sensors/lsm303agr.html

The syscall interface is described in lsm303dlhc.md

§Usage

ⓘ
let mux_i2c = components::i2c::I2CMuxComponent::new(&stm32f3xx::i2c::I2C1)
    .finalize(components::i2c_mux_component_helper!());

let lsm303dlhc = components::lsm303dlhc::Lsm303agrI2CComponent::new()
   .finalize(components::lsm303dlhc_i2c_component_helper!(mux_i2c));

lsm303dlhc.configure(
   lsm303dlhc::Lsm303AccelDataRate::DataRate25Hz,
   false,
   lsm303dlhc::Lsm303Scale::Scale2G,
   false,
   true,
   lsm303dlhc::Lsm303MagnetoDataRate::DataRate3_0Hz,
   lsm303dlhc::Lsm303Range::Range4_7G,
);

NideDof Example

ⓘ
let grant_cap = create_capability!(capabilities::MemoryAllocationCapability);
let grant_ninedof = board_kernel.create_grant(&grant_cap);

// use as primary NineDof Sensor
let ninedof = static_init!(
   capsules::ninedof::NineDof<'static>,
   capsules::ninedof::NineDof::new(lsm303dlhc, grant_ninedof)
);

hil::sensors::NineDof::set_client(lsm303dlhc, ninedof);

// use as secondary NineDof Sensor
let lsm303dlhc_secondary = static_init!(
   capsules::ninedof::NineDofNode<'static, &'static dyn hil::sensors::NineDof>,
   capsules::ninedof::NineDofNode::new(lsm303dlhc)
);
ninedof.add_secondary_driver(lsm303dlhc_secondary);
hil::sensors::NineDof::set_client(lsm303dlhc, ninedof);

Temperature Example

ⓘ
let grant_cap = create_capability!(capabilities::MemoryAllocationCapability);
let grant_temp = board_kernel.create_grant(&grant_cap);

lsm303dlhc.configure(
   lsm303dlhc::Lsm303AccelDataRate::DataRate25Hz,
   false,
   lsm303dlhc::Lsm303Scale::Scale2G,
   false,
   true,
   lsm303dlhc::Lsm303MagnetoDataRate::DataRate3_0Hz,
   lsm303dlhc::Lsm303Range::Range4_7G,
);
let temp = static_init!(
capsules::temperature::TemperatureSensor<'static>,
    capsules::temperature::TemperatureSensor::new(lsm303dlhc, grant_temperature));
kernel::hil::sensors::TemperatureDriver::set_client(lsm303dlhc, temp);
