Angle 6 click

Angle 6 Click is a compact add-on board that detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. This board features the MAQ470GQE, a 12-bit contactless angle sensor with PWM output from Monolithic Power Systems. 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 speeds from 0 to 60,000 rpm, alongside magnetic field strength detection with programmable thresholds.

Click library

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

Software Support

We provide a library for the Angle 6 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Angle 6 Click driver.

Standard key functions :

Example key functions :

  • angle6_write_register This function writes a data byte to the selected register by using SPI serial interface.
    err_t angle6_write_register ( angle6_t *ctx, uint8_t reg, uint8_t data_in );
  • angle6_read_register This function reads a data byte from the selected register by using SPI serial interface.
    err_t angle6_read_register ( angle6_t *ctx, uint8_t reg, uint8_t *data_out );
  • angle6_read_angle This function reads raw angle data and converts it to degrees.
    err_t angle6_read_angle ( angle6_t *ctx, float *angle );

Example Description

This example demonstrates the use of Angle 6 click board by reading and displaying the magnet's angular position in degrees.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration which sets the rotation direction to clockwise.

void application_init ( void )
{
log_cfg_t log_cfg;
angle6_cfg_t angle6_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
angle6_cfg_setup( &angle6_cfg );
ANGLE6_MAP_MIKROBUS( angle6_cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == angle6_init( &angle6, &angle6_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( ANGLE6_ERROR == angle6_default_cfg ( &angle6 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads the magnet's angular position in degrees and displays the results on the USB UART approximately every 100ms.

void application_task ( void )
{
float angle = 0;
if ( ANGLE6_OK == angle6_read_angle ( &angle6, &angle ) )
{
log_printf ( &logger, " Angle: %.2f Deg \r\n\n", angle );
Delay_ms ( 100 );
}
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Angle6

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. UART terminal is available in all MikroElektronika compilers.
