Hardware Overview
How does it work?
AudioAMP 12 Click is based on the TS2007FC, a filter-free class-D audio amplifier from STMicroelectronics. The amplifier can work in differential configuration or single-ended input configuration. You can choose one over the INPUT SEL jumper, where the SE (single-ended) is set by default. The amplifier is a monolithic, fully differential input/output amplifier, which includes a common mode feedback loop that controls the output bias value to average it in correlation to the DC common mode input voltage range. This, in turn, allows the amplifier always to have a maximum output voltage swing and maximize the output power. Compared to the single-ended topology, the output is four times higher for
the same power supply voltages. The amplifier allows switching between two fixed gains: 6 or 12dB (2 or 4V/V gain). It also features thermal shutdown protection, output short-circuit protection, and a low pop-and-click noise, where the signal-to-noise ratio is typically 90dB. The pop-and-click reduction circuitry and low ON/OFF switching noise typically allow the amplifier to start within 1ms. You can also choose the Standby mode function, which keeps the current consumption down to 1μA. This Click board™ features a standard 3.5mm audio jack to connect the audio input. In addition to the audio jack, there is also an unpopulated 3-pin header if you want to connect the audio input by other means.
AudioAMP 12 Click allows connecting one speaker over the onboard terminal. This Click board™ uses general-purpose input/output pins to communicate with the host MCU. Using the GS pin, you can select one of the available gains with IOs logic states. The STB pin is a Standby pin with active LOW logic. 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
Arduino UNO is a versatile microcontroller board built around the ATmega328P chip. It offers extensive connectivity options for various projects, featuring 14 digital input/output pins, six of which are PWM-capable, along with six analog inputs. Its core components include a 16MHz ceramic resonator, a USB connection, a power jack, an
ICSP header, and a reset button, providing everything necessary to power and program the board. The Uno is ready to go, whether connected to a computer via USB or powered by an AC-to-DC adapter or battery. As the first USB Arduino board, it serves as the benchmark for the Arduino platform, with "Uno" symbolizing its status as the
first in a series. This name choice, meaning "one" in Italian, commemorates the launch of Arduino Software (IDE) 1.0. Initially introduced alongside version 1.0 of the Arduino Software (IDE), the Uno has since become the foundational model for subsequent Arduino releases, embodying the platform's evolution.

Accessories
Click Shield for Arduino UNO has two proprietary mikroBUS™ sockets, allowing all the Click board™ devices to be interfaced with the Arduino UNO board without effort. The Arduino Uno, a microcontroller board based on the ATmega328P, provides an affordable and flexible way for users to try out new concepts and build prototypes with the ATmega328P microcontroller from various combinations of performance, power consumption, and features. The Arduino Uno has 14 digital input/output pins (of which six can be used as PWM outputs), six analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header, and reset button. Most of the ATmega328P microcontroller pins are brought to the IO pins on the left and right edge of the board, which are then connected to two existing mikroBUS™ sockets. This Click Shield also has several switches that perform functions such as selecting the logic levels of analog signals on mikroBUS™ sockets and selecting logic voltage levels of the mikroBUS™ sockets themselves. Besides, the user is offered the possibility of using any Click board™ with the help of existing bidirectional level-shifting voltage translators, regardless of whether the Click board™ operates at a 3.3V or 5V logic voltage level. Once you connect the Arduino UNO board with our Click Shield for Arduino UNO, you can access hundreds of Click boards™, working with 3.3V or 5V logic voltage levels.

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 example demonstrates the use of AudioAMP 12 Click board™.
* The library contains an API for switching between two gain settings
* and device control selection between operation and standby mode.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization of GPIO module and log UART. After driver initialization,
* the app sets default settings performs a power-up sequence, and sets the sound volume to 6 dB.
*
* ## Application Task
* The app performs circles the volume switch between two gain settings,
* 6 dB or 12 dB, every 5 seconds.
* Results are being sent to the UART Terminal, where you can track their changes.
