Der 6DOF IMU 17 Click Board™ ist eine kompakte Zusatzplatine, die eine 6-achsige Trägheitsmesseinheit enthält. Diese Platine verfügt über das IIM-42652, ein 6-achsiges SmartIndustrial™ MotionTracking-Gerät, das einen erweiterten Betriebstemperaturbereich für industrielle Anwendungen von TDK InvenSense unterstützt. Es kombiniert ein 3-achsiges Gyroskop und einen 3-achsigen Beschleunigungsmesser mit einem 2K-Byte-FIFO, das den Datenverkehr auf der seriellen Busschnittstelle (SPI oder I2C) verringern und den Stromverbrauch reduzieren kann, indem der Systemprozessor Sensordaten in Burst-Schritten lesen und dann in einen Energiesparmodus wechseln kann. Dieses Click Board™ ist eine ausgezeichnete Wahl für Anwendungen wie Neigungserkennung, Navigation, Orientierungsmessung, Plattformstabilisierung, Robotik und vieles mehr.
Das 6DOF IMU 17 Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.
How Does The 6DOF IMU 17 Click Board™ Work?
The 6DOF IMU 17 Click Board™ as its foundation uses the IIM-42652, a 6-axis motion tracking device that combines a 3-axis gyroscope and a 3-axis accelerometer from TDK InvenSense. It features a 2K-byte FIFO that can lower the traffic on the selected serial bus interface and reduce power consumption by allowing the system processor to burst read sensor data and then go into a low-power mode. With its 6-axis integration, the IIM-42652 guarantees optimal motion performance for customers. The IIM-42652 supports an extended operating temperature range up to 105°C, allowing customers to design it into a wide range of industrial IoT applications, including navigation and stabilizing industrial machinery and robots.
The gyroscope supports eight programmable full-scale range settings from ±15.625dps to ±2000dps, and the accelerometer supports four programmable full-scale range settings from ±2g to ±16g. Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts. The IIM-42652 also provides high robustness by supporting 20,000g shock reliability.
The 6DOF IMU 17 Click Board™ provides the possibility of using both I2C and SPI interfaces with a maximum frequency of 1MHz for I2C and 24MHz for SPI communication. The selection can be made by positioning SMD jumpers labelled as COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive.
Interrupt functionality is configured via the Interrupt Configuration register, which allows for interrupt pin configuration routed to the INT pin of the mikroBUS™ socket (used to signal MCU that an event has been sensed), the interrupt latching and clearing method, and triggers for the interrupt. The interrupt status can be read from the Interrupt Status register.
The 6DOF IMU 17 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.

Additional Notes and Information
Depending on the development board you are using, you may need a 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.
MIKROSDK
This 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.
