Hardware Overview

How does it work?

9DOF 3 Click is based on the BMX055, an integrated 9-axis sensor for detecting movements, rotations, and magnetic heading from Bosch Sensortec. It comprises the full functionality of a triaxial, low-g acceleration sensor, a triaxial angular rate sensor, and a triaxial geomagnetic sensor. The BMX055 senses orientation, tilt motion, acceleration, rotation, shock, vibration, and heading in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features, and game controllers. The BMX055 allows accurate measurements of angular rate, acceleration, and geomagnetic fields in 3 perpendicular axes within one device. The programmable measurement ranges are ±2g, ±4g, ±8g, 16g for accelerometer, ±125°/s, ±250°/s, ±500°/s, ±1000°/s, ±2000°/s for gyroscope and 1300µT (x,y), 2500µT (z) for the magnetometer. The smallest to be distinguished magnitude from the measured

value, or short for resolution, is 0.98mg, 0.004°/s, and 0.3µT for the accelerometer, gyroscope, and magnetometer, respectively. Several power modes are configurable for each sensor intended for low-power applications and power saving. The data from sensors are acquired via a selected digital interface, either SPI or I2C, by reading the addresses directly. Featured IC possesses a 16-bit gyroscope, 12-bit accelerometer, and a full-performance geomagnetic sensor that provides data in 2's complement representation. Measured data compensation and calibration are also included as an on-chip feature and a temperature sensor for reducing temperature fluctuations on sensitive components. 9DOF 3 Click supports two serial digital interface protocols for communication as a peripheral with a host device: SPI and I2C. The active interface is selected by soldering the SMD jumpers to an appropriate

position. The I2C address can also be configured by an SMD jumper when the Click board™ is operated in the I2C mode. The SMD jumpers labeled ADDR SEL are used to set the I2C address of the BMX055. The BMX055 module supports four interrupt pins for each sensor: Accel_INT, Gyro_INT, Mag_INT, and DRDY. The sensor interrupt is selectable via one cross-shaped jumper selection and routed to the Mikrobus INT pin. There is also a header on top of the click with the breakout of all available sensor interrupt pins. This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Features overview

Development board

Clicker 2 for Kinetis is a compact starter development board that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It comes with an onboard 32-bit ARM Cortex-M4F microcontroller, the MK64FN1M0VDC12 from NXP Semiconductors, two mikroBUS™ sockets for Click board™ connectivity, a USB connector, LED indicators, buttons, a JTAG programmer connector, and two 26-pin headers for interfacing with external electronics. Its compact design with clear and easily recognizable silkscreen markings allows you to build gadgets with unique functionalities and

features quickly. Each part of the Clicker 2 for Kinetis development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the Clicker 2 for Kinetis programming method, using a USB HID mikroBootloader or an external mikroProg connector for Kinetis programmer, the Clicker 2 board also includes a clean and regulated power supply module for the development kit. It provides two ways of board-powering; through the USB Micro-B cable, where onboard voltage regulators provide the appropriate voltage levels to each component on the board, or

using a Li-Polymer battery via an onboard battery connector. All communication methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, reset button, and several user-configurable buttons and LED indicators. Clicker 2 for Kinetis 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.

Application Output Step 1

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™.

Application Output Step 3

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.

Application Output Step 4

 * # Description
 * This click introduces a small-scale absolute orientation sensor in the class of low-noise 
 * 9-axis measurement units. It comprises the full functionality of a triaxial, low-g acceleration 
 * sensor, a triaxial angular rate sensor and a triaxial geomagnetic sensor. All three sensor 
 * components can be operated and addressed independently from each other. 9DOF 3 Click offers 
 * both SPI and I2C digital interfaces
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enables - I2C or SPI, check communication, 
 * set default configuration for accelerometer, gyroscope and magnetometer, also write log.
 * 
 * ## Application Task  
 * This is an example which demonstrates the use of 9DOF 3 Click board.
 * Measures and displays Accel, Gyroscope and Magnetometer values for X-axis, Y-axis and Z-axis.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on USB uart changes for every 1 sec.
