Angle 8 Click

Angle 8 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.


Click Library

  • Author : Stefan Filipovic
  • Date : Dec 2021.
  • Type : SPI type

Software Support

Example Description

This example demonstrates the use of Angle 8 Click board by reading and displaying the magnet's angular position in degrees.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Angle8

Example Key Functions

  • angle8_cfg_setup Config Object Initialization function.
    void angle8_cfg_setup(angle8_cfg_t *cfg)
    Angle 8 configuration object setup function.
    Angle 8 Click configuration object.
    Definition angle8.h:207
  • angle8_init Initialization function.
    err_t angle8_init ( angle8_t *ctx, angle8_cfg_t *cfg );
    err_t angle8_init(angle8_t *ctx, angle8_cfg_t *cfg)
    Angle 8 initialization function.
    Angle 8 Click context object.
    Definition angle8.h:186
  • angle8_default_cfg Click Default Configuration function.
    err_t angle8_default_cfg(angle8_t *ctx)
    Angle 8 default configuration function.
  • angle8_get_nd_pin This function returns the new data ready (ND) pin logic state.
    uint8_t angle8_get_nd_pin ( angle8_t *ctx );
    uint8_t angle8_get_nd_pin(angle8_t *ctx)
    Angle 8 get nd pin function.

    err_t angle8_set_cycle_time ( angle8_t *ctx, float time_ms );
    err_t angle8_set_cycle_time(angle8_t *ctx, float time_ms)
    Angle 8 set cycle time function.
  • angle8_read_angle This function reads raw angle data and converts it to degrees.

    err_t angle8_read_angle(angle8_t *ctx, float *angle)
    Angle 8 read angle function.

Application Init

Initializes the driver and performs the Click default configuration which sets the clockwise rotation direction and cycle time to 100ms.

void application_init ( void )
{
log_cfg_t log_cfg;
angle8_cfg_t angle8_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
angle8_cfg_setup( &angle8_cfg );
ANGLE8_MAP_MIKROBUS( angle8_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == angle8_init( &angle8, &angle8_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( ANGLE8_ERROR == angle8_default_cfg ( &angle8 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Waits for the new data ready flag and then reads the magnet's angular position in degrees and displays the results on the USB UART.

void application_task ( void )
{
if ( angle8_get_nd_pin ( &angle8 ) )
{
float angle = 0;
if ( ANGLE8_OK == angle8_read_angle ( &angle8, &angle ) )
{
log_printf ( &logger, " Angle: %.2f Deg \r\n\n", angle );
}
}
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
