The GMR Angle Click Board™ contains the TLI5012B E1000 from Infineon Technologies AG, GMR-based is a 360° angle sensor, for detects any kind the orientation of a magnetic field, and the analog multiplexer 74HCT4053, switch a bi-directional Synchronous Serial Communication DATA line. This is achieved by measuring sine and cosine angle components with monolithic integrated Giant Magneto Resistance (iGMR) elements. These raw signals (sine and cosine) are digitally processed internally to calculate the angle orientation of the magnetic field (magnet).
The calibration parameters are stored in laser fuses. At start-up the values of the fuses are written into flip-flops, where these values can be changed by the application-specific parameters. Further precision of the angle measurement over a wide temperature range and a long lifetime are improved with the internal autocalibration algorithm.
The Giant Magneto Resistance (GMR) sensor is implemented using vertical integration. This means that the GMR-sensitive areas are integrated above the logic part of the TLI5012B E1000 device. These GMR elements change their resistance depending on the direction of the magnetic field. Four individual GMR elements are connected to one Wheatstone sensor bridge. These GMR elements sense one of two components of the applied magnetic field: • X component, Vx (cosine) or the • Y component, Vy (sine) With this full-bridge structure the maximum GMR signal is available and temperature effects cancel out each other
The GMR Angle Click Board™ also features the 74HCT4053, which is a triple single-pole double-throw analog switch (3x SPDT) suitable for use in analog or digital 2:1 multiplexer/demultiplexer applications. Each switch features a digital select input (Sn), two independent inputs/outputs (nY0 and nY1) and a common input/output (nZ). A digital enable input (E) is common to all switches. When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. When CSS pin on microBUS is HIGH, switches in multiplexer connect DATA line with MOSI line, in other case when CSS pin is LOW, swithces connect DATA line with MISO line.
The 74HCT4053 is mainly used for Analog multiplexing and demultiplexing, Digital multiplexing and demultiplexing and Signal gating, but in this one the 74HCT4053 is used for selection SPI line.
These feature enable the GMR Angle Click Board™ to be used for various applications, most notably for angular position sensing in industrial and consumer applications such as electrical commutated motor (e.g. BLDC), fans or pumps.

The demo can run on all the main MikroElektronika development boards.
The library covers all the necessary functions to control GMR Angle click board. A library performs a standard SPI interface communication.
uint16_t gmrangle_readData( uint8_t registerAddress ) - Generic read 16-bit data function.void gmrangle_writeData( uint8_t registerAddress, uint16_t writeData ) - Generic write 16-bit data function.float gmrangle_calculateAngle() - Calculate angle function.The application is composed of three sections :
void applicationTask()
{
angle = gmrangle_calculateAngle();
FloatToStr( angle, logText );
mikrobus_logWrite( " Angle is ", _LOG_TEXT );
mikrobus_logWrite( logText, _LOG_TEXT );
mikrobus_logWrite( degCel, _LOG_LINE );
mikrobus_logWrite( "---------------------", _LOG_LINE );
Delay_1sec();

Other mikroE Libraries used in the example:
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.
The GMR Angle Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
