Hardware Overview
How does it work?
Brushless 2 Click is based on the DRV10964, a BLDC motor controller with an integrated output stage from Texas Instruments. This Click board™ is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over the following pins on the mikroBUS™ line: AN, RST, CS, PWM, and INT. A 3-wire BLDC motor
can be connected over the screw terminals; speed is controlled through a PWM pin on the mikroBUS™ line. The click also has feedback on the interrupt pin (INT), so you can see exactly how fast the motor goes. The DRV10964 is a three-phase sensorless motor driver with integrated power MOSFETs. It is specifically designed for
high-efficiency, low-noise, and low-external component-count motor drive applications. The proprietary sensorless windowless 180° sinusoidal control scheme offers ultra-quiet motor drive performance. The DRV10964 contains an intelligent lock detect function and other internal protection circuits to ensure safe operation.
Features overview
Development board
PIC32MZ Clicker 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 PIC32MZ microcontroller with FPU from Microchip, a USB connector, LED indicators, buttons, a mikroProg connector, and a header for interfacing with external electronics. Thanks to its compact design with clear and easy-recognizable silkscreen markings, it provides a fluid and immersive working experience, allowing access anywhere and under
any circumstances. Each part of the PIC32MZ Clicker development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the PIC32MZ Clicker programming method, using USB HID mikroBootloader, or through an external mikroProg connector for PIC, dsPIC, or PIC32 programmer, the Clicker board also includes a clean and regulated power supply module for the development kit. The USB Micro-B connection can provide up to 500mA of current, which is more than enough to operate all onboard
and additional modules. All communication methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, reset button, and several buttons and LED indicators. PIC32MZ 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
1. Application Output - In Debug mode, the 'Application Output' window enables real-time data monitoring, offering direct insight into execution results. Ensure proper data display by configuring the environment correctly using the provided tutorial.
2. UART Terminal - Use the UART Terminal to monitor data transmission via a USB to UART converter, allowing direct communication between the Click board™ and your development system. Configure the baud rate and other serial settings according to your project's requirements to ensure proper functionality. For step-by-step setup instructions, refer to the provided tutorial.
3. Plot Output - The Plot feature offers a powerful way to visualize real-time sensor data, enabling trend analysis, debugging, and comparison of multiple data points. To set it up correctly, follow the provided tutorial, which includes a step-by-step example of using the Plot feature to display Click board™ readings. To use the Plot feature in your code, use the function: plot(*insert_graph_name*, variable_name);. This is a general format, and it is up to the user to replace 'insert_graph_name' with the actual graph name and 'variable_name' with the parameter to be displayed.

* # Description
* This application controlled speed motor.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization driver enable's - GPIO, PWM initialization
*
* ## Application Task
* This is a example which demonstrates the use of Brushless 2 Click board.
* Brushless 2 Click communicates with register via PWM interface.
* Results are being sent to the Usart Terminal where you can track their changes.
