Hardware Overview
How does it work?
Tilt 6 Click is based on the TM1000Q, a tilt switch from E-Switch designed to detect changes in orientation with high precision and reliability. This switch offers a long operational lifespan of up to 1,000,000 cycles. With a maximum contact resistance of 5Ω, minimum insulation resistance of 100MΩ at 500VDC, and dielectric strength of 500VAC for one minute, the TM1000Q ensures stable and safe operation even in demanding environments. The switch is triggered when the board is tilted at a 45-degree angle from the horizontal plane, providing accurate tilt detection for various applications. This Click board™ features two orange LED indicators, LD2 and LD3, which illuminate to signal the direction of the tilt, with LD2 indicating a tilt to the left at a 45-degree angle from
the horizontal plane and LD3 indicating a tilt to the right. These LEDs correspond to the switch output signals, also available on the O1 and O2 pins of the mikroBUS™ socket, for further processing by the host MCU. This environmentally friendly switch is mercury-free and uses silver contacts for reliable electrical performance. The TM1000Q operates with a single-pole, single-throw (SPST) functionality, making Tilt 6 Click an excellent choice for applications requiring precise orientation detection, such as industrial equipment, safety systems, and motion-based controls. Tilt 6 Click is designed in a unique format supporting the newly introduced MIKROE feature called "Click Snap." Unlike the standardized version of Click boards, this feature allows the main IC area to become
movable by breaking the PCB, opening up many new possibilities for implementation. Thanks to the Snap feature, the TM1000Q can operate autonomously by accessing its signals directly on the pins marked 1-8. Additionally, the Snap part includes a specified and fixed screw hole position, enabling users to secure the Snap board in their desired location. 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. Also, this 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
Curiosity PIC32 MZ EF development board is a fully integrated 32-bit development platform featuring the high-performance PIC32MZ EF Series (PIC32MZ2048EFM) that has a 2MB Flash, 512KB RAM, integrated FPU, Crypto accelerator, and excellent connectivity options. It includes an integrated programmer and debugger, requiring no additional hardware. Users can expand
functionality through MIKROE mikroBUS™ Click™ adapter boards, add Ethernet connectivity with the Microchip PHY daughter board, add WiFi connectivity capability using the Microchip expansions boards, and add audio input and output capability with Microchip audio daughter boards. These boards are fully integrated into PIC32’s powerful software framework, MPLAB Harmony,
which provides a flexible and modular interface to application development a rich set of inter-operable software stacks (TCP-IP, USB), and easy-to-use features. The Curiosity PIC32 MZ EF development board offers expansion capabilities making it an excellent choice for a rapid prototyping board in Connectivity, IOT, and general-purpose applications.

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.
Software Support
Library Description
Tilt 6 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.
Example Description
This example demonstrates the functionality of the Tilt 6 Click, which detects tilt motion in multiple directions. The example continuously monitors tilt movements, logging when the sensor detects a left tilt, right tilt, or remains idle.
Key functions:
tilt6_cfg_setup- This function initializes Click configuration structure to initial values.tilt6_init- This function initializes all necessary pins and peripherals used for this Click board.tilt6_get_tilt_state- This function returns the tilt switch state.
Application Init
Initializes the logger and configures the Tilt 6 Click.
Application Task
Continuously reads the tilt state and logs changes. The sensor can detect three states: "RIGHT TILT", "LEFT TILT", and "IDLE" indicating no tilt.
Open Source
Code example
The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
