Hardware Overview

How does it work?

Magneto 11 Click is based on the AS5510, a 10-bit linear position sensor with digital position (interface) output from ams AG. The AS5510 can measure the absolute position of lateral movement in combination with a diametrical two-pole magnet. The sensor needs a simple 2-pole magnet to measure a lateral movement, and the measured distance depends on the magnet geometry. Depending on the magnet size, a lateral stroke of 0.5mm ~ 2mm can be measured with air gaps around 1.0mm. With stronger magnets, even higher lateral strokes and air gaps are possible. The AS5510 comes in a version of a ±50mT full-scale sensing range to deliver the highest

reliability and durability in contactless position measurements. By selecting different measurement ranges, it is possible to choose different sensitivity values; the default sensitivity value of the AS5510 is 97.66µT/LSB. It also features a Power-Down mode that helps save energy and maximize run-time in battery-powered applications. Magneto 11 Click communicates with MCU using the standard I2C 2-Wire interface for switching between four different sensitivity ranges and for simple data transmission to an MCU, supporting Fast Mode Plus operation with a clock frequency up to 1MHz. The absolute position is measured with a resolution of 10 bit = 1024

positions, and it is provided as a digital value on the serial interface. Besides, the AS5510 allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labeled ADDR SEL. The selection can be made by positioning the SMD jumper to an appropriate position marked as 1 or 0. This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it 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

UNI Clicker is a compact development board designed as a complete solution that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It supports a wide range of microcontrollers, such as different ARM, PIC32, dsPIC, PIC, and AVR from various vendors like Microchip, ST, NXP, and TI (regardless of their number of pins), four mikroBUS™ sockets for Click board™ connectivity, a USB connector, LED indicators, buttons, a debugger/programmer connector, and two 26-pin headers for interfacing with external electronics. Thanks to innovative manufacturing technology, it allows you to build

gadgets with unique functionalities and features quickly. Each part of the UNI Clicker development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the UNI Clicker programming method, using a third-party programmer or CODEGRIP/mikroProg connected to onboard JTAG/SWD header, the UNI Clicker board also includes a clean and regulated power supply module for the development kit. It provides two ways of board-powering; through the USB Type-C (USB-C) connector, where onboard voltage regulators provide the appropriate voltage levels to each component on the board, or using a Li-Po/Li

Ion battery via an onboard battery connector. All communication methods that mikroBUS™ itself supports are on this board (plus USB HOST/DEVICE), including the well-established mikroBUS™ socket, a standardized socket for the MCU card (SiBRAIN standard), and several user-configurable buttons and LED indicators. UNI 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

After loading the code example, pressing the "DEBUG" button builds and programs it on the selected setup.

Application Output Step 1

After programming is completed, a header with buttons for various actions available in the IDE appears. By clicking the green "PLAY "button, we start reading the results achieved with Click board™.

Application Output Step 3

Upon completion of programming, the Application Output tab is automatically opened, where the achieved result can be read. In case of an inability to perform the Debug function, check if a proper connection between the MCU used by the setup and the CODEGRIP programmer has been established. A detailed explanation of the CODEGRIP-board connection can be found in the CODEGRIP User Manual. Please find it in the RESOURCES section.

 * @file main.c
 * @brief Magneto11 Click example
 * # Description
 * This example demonstrates the use of Magneto 11 click board by reading and displaying
 * the magnetic field strength value.
 * The demo application is composed of two sections :
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 * ## Application Task
 * Reads the magnetic field strength value in milliTesla and displays the results on the USB UART
 * every 200ms approximately.
