Namespace

The class and it's registers are scoped within the LIS3MDL namespace.

E.g LIS3MDL::REGISTER::STATUS_REG, LIS3MDL::OUTPUT_DATA_RATES::ODR_1000_HZ

Usage

• SPI constructor (recommended)

#define LIS_CS 37
LIS3MDL::LIS3MDL LIS(LIS_CS, SPI, 4000000);

• I2C constructor

LIS3MDL::LIS3MDL LIS(&Wire, 1000000);

Wiring guide:

graph TD;
    mcu[MCU] -- SCK  ---LIS3MDL[LIS3MDL];
    mcu-- MOSI  ---LIS3MDL[LIS3MDL]
    mcu-- MISO  ---LIS3MDL[LIS3MDL]
    mcu-- CS  ---LIS3MDL[LIS3MDL] 
    
    mcu2[MCU] -- SCL  ---LIS3MDL_2[LIS3MDL];
    mcu2 -- SDA  ---LIS3MDL_2[LIS3MDL]

Loading

It is recommended to call LIS.default_configuration() in your setup function. Individual settings can then be changed as required. E.g.

LIS.set_mag_ODR(LIS3MDL::OUTPUT_DATA_RATES::ODR_1000_HZ);
