Hardware Overview
How does it work?
DC MOTOR 10 Click is based on the TLE 6208-6 G, a fully protected Hex-Half-Bridge-Driver explicitly designed for automotive and industrial motion control applications from Infineon Technologies. It integrates an efficient H-Bridge with a low ON resistance of approximately 0.8Ω through each branch. Furthermore, the built-in features like Over- and Undervoltage-Lockout, Over-Temperature-Protection, and the low quiescent current in standby mode open a wide range of automotive- and industrial applications. DC MOTOR 10 Click is ideally suited for the rapid development of various DC motor driving applications, including home appliances, printers, industrial equipment, mechatronic applications, and more. The part is based on Infineon Smart Power Technology SPT®, which
allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuitry. The six low and high-side drivers are freely configurable and can be controlled separately. Therefore all kinds of loads can be combined. In motion control, up to 5 actuators (DCMotors) can be connected to the six half-bridge outputs (cascade configuration). Operation modes forward (CW), reverse (CCW), brake, and high impedance are controlled from a standard SPI-Interface. Controlling the outputs via software from a central logic allows for limiting power dissipation. The internal logic of TLE 6208-6 G is supplied by the VCC voltage, typical with 5V. The VCC voltage uses an internally generated Power-On Reset (POR) to initialize
the module at Power-on. The advantage of this system is that information stored in the logic remains intact in the event of short-term failures in the supply voltage VS. The system can therefore continue to operate following VS undervoltage without having to be reprogrammed. The undervoltage information is stored and can be read out via the interface. This Click board™ can only be operated with a 5V logic voltage level. The board must perform appropriate logic voltage level conversion before using 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.
Features overview
Development board
Fusion for PIC v8 is a development board specially designed for the needs of rapid development of embedded applications. It supports a wide range of microcontrollers, such as different PIC, dsPIC, PIC24, and PIC32 MCUs regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over WiFi. The development board is well organized and designed so that the end-user has all the necessary elements, such as switches, buttons, indicators, connectors, and others, in one place. Thanks to innovative manufacturing technology, Fusion for PIC v8 provides a fluid and immersive working experience, allowing access anywhere and under any
circumstances at any time. Each part of the Fusion for PIC v8 development board contains the components necessary for the most efficient operation of the same board. In addition to the advanced integrated CODEGRIP programmer/debugger module, which offers many valuable programming/debugging options and seamless integration with the Mikroe software environment, the board also includes a clean and regulated power supply module for the development board. It can use a wide range of external power sources, including a battery, an external 12V power supply, and a power source via the USB Type-C (USB-C) connector. Communication options such as USB-UART, USB
HOST/DEVICE, CAN (on the MCU card, if supported), and Ethernet are also included, including the well-established mikroBUS™ standard, a standardized socket for the MCU card (SiBRAIN standard), and two display options (graphical and character-based LCD). Fusion for PIC v8 is an integral part of the Mikroe ecosystem for rapid development. Natively supported by Mikroe software tools, it covers many aspects of prototyping and development thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Accessories
DC Gear Motor - 430RPM (3-6V) represents an all-in-one combination of a motor and gearbox, where the addition of gear leads to a reduction of motor speed while increasing the torque output. This gear motor has a spur gearbox, making it a highly reliable solution for applications with lower torque and speed requirements. The most critical parameters for gear motors are speed, torque, and efficiency, which are, in this case, 520RPM with no load and 430RPM at maximum efficiency, alongside a current of 60mA and a torque of 50g.cm. Rated for a 3-6V operational voltage range and clockwise/counterclockwise rotation direction, this motor represents an excellent solution for many functions initially performed by brushed DC motors in robotics, medical equipment, electric door locks, and much more.

Application Output
After pressing the "FLASH" button on the left-side panel, it is necessary to open the UART terminal to display the achieved results. By clicking on the Tools icon in the right-hand panel, multiple different functions are displayed, among which is the UART Terminal. Click on the offered "UART Terminal" icon.
Once the UART terminal is opened, the window takes on a new form. At the top of the tab are two buttons, one for adjusting the parameters of the UART terminal and the other for connecting the UART terminal. The tab's lower part is reserved for displaying the achieved results. Before connecting, the terminal has a Disconnected status, indicating that the terminal is not yet active. Before connecting, it is necessary to check the set parameters of the UART terminal. Click on the "OPTIONS" button.
In the newly opened UART Terminal Options field, we check if the terminal settings are correct, such as the set port and the Baud rate of UART communication. If the data is not displayed properly, it is possible that the Baud rate value is not set correctly and needs to be adjusted to 115200. If all the parameters are set correctly, click on "CONFIGURE".
The next step is to click on the "CONNECT" button, after which the terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.

* # Description
* This example is running dc motors on channels 1 through 3.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initalizes SPI, click drivers and uninhibites the device.
*
* ## Application Task
* This example demonstrates the use of DC MOTOR 10 click by running dc motors
* on channels 1 through 3, first all 3 together and then separately.
