Hardware Overview
How does it work?
6DOF IMU 5 Click is based on the ICM-20789, a 6-axis inertial sensor (3-axis gyroscope and a 3-axis accelerometer), and ultra-low noise MEMS capacitive barometric pressure sensor from TDK InvenSense. ICM-20789 features a 4 KB FIFO that can lower the traffic on the serial bus interface. The digital output barometric pressure sensor is based on an ultra-low noise innovative MEMS capacitive technology that can measure pressure differences with an accuracy of ±1 Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm without the penalty of increased power consumption or reduced sensor throughput. The capacitive pressure sensor has a ±1 hPa absolute accuracy over its full range of 300 hPa -1100 hPa. The pressure sensor offers industry leading temperature stability of the pressure sensor with a temperature coefficient offset of ±0.5 Pa/°C, embedded temperature sensor and 400kHz I2C
bus for communication. The gyroscope has a programmable full-scale range of ±250 dps, ±500 dps, ±1000 dps, and ±2000 dps. The accelerometer has a user-programmable full-scale range of ±2g, ±4g, ±8g, and ±16g. Factory-calibrated initial sensitivity of both sensors reduces production-line calibration requirements. Other features include on-chip 16-bit ADCs, programmable digital filters, another embedded temperature sensor, and programmable interrupts. The device features I2C serial interface to access its registers at 400 kHz as well as at 8 MHz SPI. The onboard chip ICM-20789 requires stable voltage for power supply of input/output pins (VDDIO) at 1.8V which also supplies the pressure sensor. 6DOF IMU 5 click does all of the power supply regulations as well as the logic level translations needed for proper operation. The MCP1826, a 1000 mA Low Dropout (LDO) linear regulator provides high-current and
low-output voltage of 1.8V to all of the essential parts of the board, while TXB0106 and PCA9306 do the SPI and I2C signal level translations, respectively, between the MCU and the ICM-20789. Interacting with the 6-axis is possible through SPI communication protocol while the I2C bus allows access to pressure sensors 16-bit address space registers. This device is intended for implementation in Drones and Flying Toys, Motion-based gaming controllers, Virtual Reality Headsets & Controllers, Indoor/Outdoor Navigation (dead-reckoning, floor/elevation/step detection). This Click Board™ uses both I2C and SPI communication interfaces. It is designed to be operated only with 3.3V logic levels. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V.
Features overview
Development board
Curiosity PIC32 MZ EF development board is a fully integrated 32-bit development platform featuring the high-performance PIC32MZ EF Series (PIC32MZ2048EFM) that has a 2MB Flash, 512KB RAM, integrated FPU, Crypto accelerator, and excellent connectivity options. It includes an integrated programmer and debugger, requiring no additional hardware. Users can expand
functionality through MIKROE mikroBUS™ Click™ adapter boards, add Ethernet connectivity with the Microchip PHY daughter board, add WiFi connectivity capability using the Microchip expansions boards, and add audio input and output capability with Microchip audio daughter boards. These boards are fully integrated into PIC32’s powerful software framework, MPLAB Harmony,
which provides a flexible and modular interface to application development a rich set of inter-operable software stacks (TCP-IP, USB), and easy-to-use features. The Curiosity PIC32 MZ EF development board offers expansion capabilities making it an excellent choice for a rapid prototyping board in Connectivity, IOT, and general-purpose applications.

Application Output via Debug Mode
1. Once the code example is loaded, pressing the "DEBUG" button initiates the build process, programs it on the created setup, and enters Debug mode.
2. After the programming is completed, a header with buttons for various actions within the IDE becomes visible. Clicking the green "PLAY" button starts reading the results achieved with the Click board™. The achieved results are displayed in the Application Output tab.

* # Description
* This example demonstrates the use of 6DOF IMU 5 click board.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver, checks the communication and sets the device
* default configuration.
*
* ## Application Task
* Measures acceleration, gyroscope, temperature and pressure data and
* displays the results on USB UART each second.
