Software Support

We provide a library for the Pedometer3 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library initializes and defines the I2C or SPI bus driver and drivers that offer a choice for writing data in register and reads data form register. The library includes function for read Accel X/Y/Z axis data, function for read pedometer stem counter, function for detect Tilt and Tap. The user also has the functions for configuration device functions for reads interrupt states.

Key functions :

• void pedometer3_getAccelAxis(int16_t *x_axis, int16_t *y_axis, int16_t *z_axis) - Functions for read Accel axis data
• uint16_t pedometer3_getPedometerStepCounter() - Functions for get pedometer step counter
• void pedometer3_getTiltPosition(uint8_t *current_pos, uint8_t *previous_pos) - Functions for get Tilt current and previous position
• void pedometer3_getTapDetection(uint8_t *tap) - Functions for get Tap detection

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C module and sets INT pin, AN pin and RST pin as INPUT and CS pin as OUTPUT
• Application Initialization - Initialization driver init and start configuration chip for measurement
• Application Task - (code snippet) - Reads Accel and High Pass Accel X/Y/Z axis and detect Tilt Position. All data logs on the USBUART every 500 ms.
• note The start configuration chip is required at the beginning of each program so that the chip wakes up and prepares for operation and measurement. What is included and set in the start-up function can be viewed in the help file.

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB 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.
