Library Description

The library contains basic functions for starting both sensors and reading data that the sensors measure.

Key functions:

  • void c13dof2_bmx160_getAxis(uint8_t sensor, T_C13DOF2_BMX160_AXIS *sAxis) - Reads Axis data from the BMX160 sensor (Accel, Gyro, Magnetic).
  • uint16_t c13dof2_bmx160_getStepCounter() - Read Step counter.
  • float c13dof2_bme680_getAmbientData(uint8_t dataIn) - Reads Ambient data from BME680 sensor (Temperature, Pressure and Humidity).

Examples description

The application is composed of three sections :

  • System Initialization - Initialization I2C or SPI module and sets all the necessary GPIO pins.
  • Application Initialization - Initializes the driver init, checks the communication and starts configuration for chips BMX160 and BME680.
  • Application Task - This example reads all parameters from those sensors (Acceleration, Gyro, Magnetic, Temperature, etc.) and shows them on USB UART log.
void applicationTask()
{
    /* BMX160 */
    c13dof2_bmx160_getAxis(_C13DOF2_BMX160_DATA_ACCEL,  &Accel);
    c13dof2_bmx160_getAxis(_C13DOF2_BMX160_DATA_GYRO,   &Gyro);
    c13dof2_bmx160_getAxis(_C13DOF2_BMX160_DATA_MAGNET, &Magnet);

    temperature_bmx160 = c13dof2_bmx160_internalTemperature();
    step_counter = c13dof2_bmx160_getStepCounter();
    c13dof2_bmx160_getInterruptStatus(&status);

    /* BME680 */
    temperature = c13dof2_bme680_getAmbientData(_C13DOF2_BME680_DATA_TEMPERATURE);
    pressure = c13dof2_bme680_getAmbientData(_C13DOF2_BME680_DATA_PRESSURE);
    humidity = c13dof2_bme680_getAmbientData(_C13DOF2_BME680_DATA_HUMIDITY);

    gas = c13dof2_bme680_getGasResistance();

    mikrobus_logWrite( "-------------------------------------------------------" , _LOG_LINE );
    mikrobus_logWrite( "------  BMX160 DATA  ------", _LOG_LINE );
    _displayData_BMX160();

    mikrobus_logWrite( "------  BME680 DATA  ------", _LOG_LINE );
    _displayData_BME680();

    mikrobus_logWrite( " ", _LOG_LINE );

    Delay_ms( 1000 );
}


Additional Functions :

  • void _interruptDetect() - display interupt state (TAP status)
  • void _displayData_BMX160() - display BMIX160 data (Accel, Gyro, Magnetic, Step counter, and internal senzor Temperature)
  • void _displayData_BME680() - display BME680 data (Temperature, Pressure, Humidity and Gas resistance)

Other mikroE Libraries used in the example:

  • I2C library
  • SPI Library
  • UART Library
  • Conversions Library

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

STSPIN820 Click

0

STSPIN820 Click is a stepper motor driver with the PWM current control, selectable microstepping up to 256 microsteps, and a wide voltage range. It is based on the STSPIN820, a stepper motor driver from STSPIN8 series. Designed to be a bullet-proof solution for the new wave of demanding industrial applications, it integrates two full-bridges with low ON resistance, the control logic, and a full set of protection features, in a small 4x4mm QFN package. Its output stage implements the PWM current control with the fixed OFF time. The device can be used with the step motor voltage ranging from 7V up to 45V, and current up to 1.5A per bridge.

Angle 8 Click

0

Angle 8 Click is a compact add-on board that detects the absolute angular position of a permanent magnet. This board features the MA782GGU, a low-power angle sensor with integrated wake-up angle detection from Monolithic Power Systems. With its power cycling ability, the MA782GGU can be optimized for applications that require low average power. It supports a wide range of magnetic field strengths and spatial configurations, with both end-of-shaft and off-axis (side-shaft mounting), supported configurations. Fast data acquisition and processing provides accurate angle measurement at an applied magnetic field of 60mT, alongside magnetic field strength detection with programmable thresholds. This Click board™ is suitable for general-purpose angle measurements, in embedded motion control applications, as a power/speed control trigger solution, and more.
