Compass 6 Click Board™
Product Code: MIKROE-4796
How Does The Compass 6 Click Board™ Work? The Compass 6 Click Board™ as its foundation uses the HSCDTD008A, a high-sensitivity three-axis terrestrial magnetism sensor from ALPS Alpine. It comes with an integrated drive circuit, signal processing circuit, and serial interface block, allowing low noise and high resolution. The HSCDTD008A can measure magnetic field strengths of ±2.4mT on each of its three axes and provides an output resolution of 0.15µT/LSB. This Click board™ represents a perfect choice for implementation in applications such as an electronic compass. At the beginning of the operation, all internal circuits and registers are set to the default state by turning the power ON. The operating mode is set to a low-power Standby mode automatically by Power-On reset. In addition to the Standby mode, this sensor also has an Active mode for power control accessible through a register command. The active mode has two states: the force state that starts measurement and outputs data by register command, and the Normal state, which performs measurement and outputs data using the internal timer trigger.
Compass 6 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency of 100kHz, Fast Mode up to 400kHz, and Fast Mode Plus up to 1MHz, in addition to the High-Speed Mode. It also features an additional ready signal, labeled as RDY and routed on the INT pin of the mikroBUS™ socket, that informs when new measured results for the host are updated.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
