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
PIC18F57Q43 Curiosity Nano evaluation kit is a cutting-edge hardware platform designed to evaluate microcontrollers within the PIC18-Q43 family. Central to its design is the inclusion of the powerful PIC18F57Q43 microcontroller (MCU), offering advanced functionalities and robust performance. Key features of this evaluation kit include a yellow user LED and a responsive
mechanical user switch, providing seamless interaction and testing. The provision for a 32.768kHz crystal footprint ensures precision timing capabilities. With an onboard debugger boasting a green power and status LED, programming and debugging become intuitive and efficient. Further enhancing its utility is the Virtual serial port (CDC) and a debug GPIO channel (DGI
GPIO), offering extensive connectivity options. Powered via USB, this kit boasts an adjustable target voltage feature facilitated by the MIC5353 LDO regulator, ensuring stable operation with an output voltage ranging from 1.8V to 5.1V, with a maximum output current of 500mA, subject to ambient temperature and voltage constraints.

Accessories
Curiosity Nano Base for Click boards is a versatile hardware extension platform created to streamline the integration between Curiosity Nano kits and extension boards, tailored explicitly for the mikroBUS™-standardized Click boards and Xplained Pro extension boards. This innovative base board (shield) offers seamless connectivity and expansion possibilities, simplifying experimentation and development. Key features include USB power compatibility from the Curiosity Nano kit, alongside an alternative external power input option for enhanced flexibility. The onboard Li-Ion/LiPo charger and management circuit ensure smooth operation for battery-powered applications, simplifying usage and management. Moreover, the base incorporates a fixed 3.3V PSU dedicated to target and mikroBUS™ power rails, alongside a fixed 5.0V boost converter catering to 5V power rails of mikroBUS™ sockets, providing stable power delivery for various connected devices.
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.

* # 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.
