Hardware Overview
How does it work?
Altitude 6 Click is based on the MS5611-01BA03-50, a high-resolution barometric pressure sensor optimized for altimeter applications with an altitude resolution of 10 cm from TE Connectivity. The MS5611-01BA03-50 consists of a piezo-resistive sensor with an integrated signal conditioning circuit that can measure pressure from 10 mbar up to 1.2bar with an accuracy of 1.5 mbar over a wide operating temperature range at the lowest power consumption. The high accuracy and stability of pressure and temperature signals make it suitable for height sensing in medical and consumer applications, mobile altimeter or barometer systems, and many more. The MS5611-01BA03-50
also has ultra-low-power 24-bit ΔΣ ADC, internal factory-calibrated coefficients, and a high linearity pressure sensor. Its primary function is to convert the uncompensated analog output voltage from the piezo-resistive pressure sensor to a 24-bit digital value and provide a 24-bit digital value for the sensor's temperature, which allows the implementation of an altimeter function without any additional sensor. Altitude 6 Click allows the use of both I2C and SPI interfaces with a maximum frequency of 20MHz. The selection can be made by positioning SMD jumpers labeled as COMM SEL in an appropriate position. Note that all the jumpers' positions must be on the same side,
or the Click board™ may become unresponsive. While the I2C interface is selected, the MS5611-01BA03 allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labeled ADDR SEL to an appropriate position marked as 0 and 1. 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
Flip&Click PIC32MZ 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 comes with an onboard 32-bit PIC32MZ microcontroller, the PIC32MZ2048EFH100 from Microchip, four mikroBUS™ sockets for Click board™ connectivity, two USB connectors, LED indicators, buttons, debugger/programmer connectors, and two headers compatible with Arduino-UNO pinout. Thanks to innovative manufacturing technology,
it allows you to build gadgets with unique functionalities and features quickly. Each part of the Flip&Click PIC32MZ development kit contains the components necessary for the most efficient operation of the same board. In addition, there is the possibility of choosing the Flip&Click PIC32MZ programming method, using the chipKIT bootloader (Arduino-style development environment) or our USB HID bootloader using mikroC, mikroBasic, and mikroPascal for PIC32. This kit includes a clean and regulated power supply block through the USB Type-C (USB-C) connector. All communication
methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, user-configurable buttons, and LED indicators. Flip&Click PIC32MZ development kit allows 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 library contains API for Altitude 6 Click driver.
* The demo application reads and calculate
* temperature, pressure and altitude data.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes I2C or SPI driver and log UART.
* After driver initialization the app set
* driver interface setup and default settings.
*
* ## Application Task
* This is an example that demonstrates the use of the Altitude 6 Click board™.
* In this example, display the Altitude ( m ),
* Pressure ( mBar ) and Temperature ( degree Celsius ) data.
* Results are being sent to the Usart Terminal where you can track their changes.
