Hardware Overview
How does it work?
Boost Click is based on the MIC2606, a 0.5A, 2MHz wide input range boost regulator with an integrated switch and Schottky diode from Microchip. Its FB (feedback) pin provides the control path to control the output. This FB pin is driven by an onboard DAC – MCP4921. This is a 2.7 – 5.5V, low-power, low DNL, 12-Bit Digital-to-Analog Converter (DAC) with an SPI interface. It provides high accuracy and low noise performance for
industrial applications. The output voltage is connected to an onboard ADC, the MCP3551, a 2.7V to 5.5V low-power, 22-bit delta-sigma analog-to-digital converter, through a voltage divider. The input voltage can be set to 5V from mikroBUS™ or 7-20V from an external DC source connected to the VIN screw terminal. The output voltage can be set up to 38V. The reference voltage for both the ADC and DAC is provided by MAX6106 – onboard
voltage reference. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCCIO 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 ARM 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 ARM® Cortex®-M based 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 ARM v8 provides a fluid and immersive working experience, allowing access anywhere and under any
circumstances at any time. Each part of the Fusion for ARM 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 ARM 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.

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.

* \brief Boost Click example
*
* # Description
* Boost click provides an adjustable output voltage through the onboard DAC that drives the FB
* pin of the MIC2606 to set desired output voltage.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes SPI driver for serial communication and puts the device to power ON state.
* Also, initializes logger module for message and results sending.
*
* ## Application Task
* This is a example which demonstrates the use of Boost Click board.
* Boost Click communicates with register via SPI by reading from MCP3551 chip and writing DAC value to the MCP4921 chip.
* This example periodicaly increases and decreases voltage in range between 15 and 30 Volts.
* All data logs write on usb uart for aproximetly every 1 sec.
