Hardware Overview
How does it work?
6DOF IMU 8 Click is based on the ISM330DLC, a 3D accelerometer and 3D gyroscope with digital output for industrial applications from STMicroelectronics. It is an advanced inertial module from iNEMO series, featuring an integrated microelectromechanical gyroscope and an accelerometer sensor (MEMS) within the same package. This device is designed with Industry 4.0 in mind, and produced using well-proven CMOS and MEMS fabrication processes, providing a high integration scale on a wafer level. This allows for a very good matching between the IC and the MEMS, offering very good robustness, mechanical shock immunity, and improved stability. Three-axis gyroscope MEMS can be programmed to measure the rotation about each axis, in five different ranges of angular speed (degrees per angle, dps): ±125, ±250, ±500, ±1000, and ±2000. Three-axis accelerometer MEMS can be programmed to measure the acceleration along each axis, in four different acceleration ranges: ±2g, ±4g, ±8g, and ±16g. The developer can select an optimal range for both properties, depending on the application requirements. The ISM330DLC incorporates a
powerful programmable interrupt engine with two dedicated interrupt pins. The interrupt engine can detect many different events, including free-fall, wakeup, 6D orientation, tap, and double-tap events, activity and inactivity recognition, as well as a tilt detection with two configurable event detection options: an average window and an average threshold. The function of these two interrupt pins is not limited to these events. They can also be used for FIFO buffer-related events, such as a buffer is full, the buffer is empty, watermark level is reached, and the buffer is overrun. Data Ready event can also be signaled for each of the two sensors (gyro and accel). The INT 1 pin is routed to the mikroBUS™ INT pin, while the INT 2 pin is routed to the mikroBUS™ AN pin. These pins are labeled as IT1 and IT2 on the Click board™, respectively. A FIFO buffer helps to reduce the communication bus traffic, processing load, and the power consumption, offering temporary storage for the output data. The ISM330DLC features a smart FIFO buffer with the capacity of 4096 bytes, which can be set to work in five different modes. The FIFO buffer is highly
configurable. It is possible to select the data to be stored from several sources (gyroscope, accelerometer, timestamp, temperature…). As already discussed, the FIFO buffer itself can trigger interrupt for several events, alerting the host MCU about its status. 6DOF IMU 8 click supports both SPI and I2C communication interfaces, allowing it to be used with a wide range of different MCUs. The communication interface can be selected by moving SMD jumpers grouped under the COM SEL to an appropriate position (SPI or I2C). The slave I2C address can also be configured by an SMD jumper when the Click board™ is operated in the I2C mode an SMD jumper labeled as ADD LSB is used to set the least significant bit (LSB) of the I2C address. When set to 1, the 7-bit I2C slave address becomes 0b1101011x. If set to 0, the address becomes 0b1101010x. The last digit (x) is the R/W bit. This Click Board™ uses both I2C and SPI communication interfaces. It is designed to be operated only with up to 3.3V logic levels. Proper conversion of logic voltage levels should be applied, before the Click board™ is used with MCUs operated at 5V.
Features overview
Development board
UNI Clicker is a compact development board designed as a complete solution that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It supports a wide range of microcontrollers, such as different ARM, PIC32, dsPIC, PIC, and AVR from various vendors like Microchip, ST, NXP, and TI (regardless of their number of pins), four mikroBUS™ sockets for Click board™ connectivity, a USB connector, LED indicators, buttons, a debugger/programmer connector, and two 26-pin headers for interfacing with external electronics. Thanks to innovative manufacturing technology, it allows you to build
gadgets with unique functionalities and features quickly. Each part of the UNI Clicker development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the UNI Clicker programming method, using a third-party programmer or CODEGRIP/mikroProg connected to onboard JTAG/SWD header, the UNI Clicker board also includes a clean and regulated power supply module for the development kit. It provides two ways of board-powering; through the USB Type-C (USB-C) connector, where onboard voltage regulators provide the appropriate voltage levels to each component on the board, or using a Li-Po/Li
Ion battery via an onboard battery connector. All communication methods that mikroBUS™ itself supports are on this board (plus USB HOST/DEVICE), including the well-established mikroBUS™ socket, a standardized socket for the MCU card (SiBRAIN standard), and several user-configurable buttons and LED indicators. UNI Clicker is an integral part of the Mikroe ecosystem, allowing you to create a new application in minutes. Natively supported by Mikroe software tools, it covers many aspects of prototyping thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output
After loading the code example, pressing the "DEBUG" button builds and programs it on the selected setup.
After programming is completed, a header with buttons for various actions available in the IDE appears. By clicking the green "PLAY "button, we start reading the results achieved with Click board™.
Upon completion of programming, the Application Output tab is automatically opened, where the achieved result can be read. In case of an inability to perform the Debug function, check if a proper connection between the MCU used by the setup and the CODEGRIP programmer has been established. A detailed explanation of the CODEGRIP-board connection can be found in the CODEGRIP User Manual. Please find it in the RESOURCES section.

* # Description
* This app gets three-axis gyroscope value, three-axis accelerometer value and temperature.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes device and performs a device software reset and configuration.
*
* ## Application Task
* Waits until any new data is entered to the data registers and then reads the accelerometer,
* gyroscope and temperature data which will be converted and calculated to the properly units each second.
