Hardware Overview

How does it work?

H-Bridge 5 Click is based on the MP6515, an H-bridge motor driver from Monolithic Power Systems (MPS). This Click board™ operates from a supply voltage of up to 30V and delivers a motor current of up to 1.5A. Its main applications include solenoid and DC brush motor driving. Its internal safety features include over-current protection, input over-voltage protection, undervoltage lockout (UVLO), and thermal shutdown. The MP6515 integrates four N-channel power MOSFETs with 2.8A peak current capability. It is designed to drive DC brush motors, solenoids, or other loads. Regarding current sensing, the current flowing in the two low-side MOSFETs is sensed with an internal current sensing circuit. A voltage that is proportional to the output

current is sourced on VISEN. Current is sensed when one of the low-side MOSFETs is turned on, including during slow decay (brake) mode. The load current applied to VISEN should be kept below 2mA, with no more than 500pF of capacitance. The H-Bridge 5 click also contains the PCA9538A, a low-voltage 8-bit General Purpose Input/Output (GPIO) expander from NXP with interrupt and reset for I2C-bus/SMBus applications. NXP I/O expander provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum. Expanders provide communication between MP6515 and MCU, MCU control expander with I2C communication, and set output logic level for I/O pins. Data is exchanged

between the master and PCA9538A through write and read commands using I2C-bus. The two communication lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Features overview

Development board

Fusion for TIVA 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 32-bit ARM® Cortex®-M based MCUs from Texas Instruments, regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over a WiFi network. 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 TIVA v8 provides a fluid and immersive working experience, allowing access

anywhere and under any circumstances at any time. Each part of the Fusion for TIVA v8 development board contains the components necessary for the most efficient operation of the same board. An advanced integrated CODEGRIP programmer/debugger module offers many valuable programming/debugging options, including support for JTAG, SWD, and SWO Trace (Single Wire Output)), and seamless integration with the Mikroe software environment. Besides, it 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 is also included. In addition, it also has the well-established mikroBUS™ standard, a standardized socket for the MCU card (SiBRAIN standard), and two display options for the TFT board line of products and character-based LCD. Fusion for TIVA 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 via UART Mode

1. Once the code example is loaded, pressing the "FLASH" button initiates the build process, and programs it on the created setup.

2. After the programming is completed, click on the Tools icon in the upper-right panel, and select the UART Terminal.

3. After opening the UART Terminal tab, first check the baud rate setting in the Options menu (default is 115200). If this parameter is correct, activate the terminal by clicking the "CONNECT" button.

4. Now terminal status changes from Disconnected to Connected in green, and the data is displayed in the Received data field.

 * # Description
 * This application controls DC motors and inductive loads.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes I2C driver, configures all ports as output and writes an initial log.
 * 
 * ## Application Task  
 * This example demonstrates the use of H-Bridge 5 Click board, by running dc motor forward, 
 * then stoping and then running it in reverse and stoping again.
