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
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 via Debug Mode
1. Once the code example is loaded, pressing the "DEBUG" button initiates the build process, programs it on the created setup, and enters Debug mode.
2. After the programming is completed, a header with buttons for various actions within the IDE becomes visible. Clicking the green "PLAY" button starts reading the results achieved with the Click board™. The achieved results are displayed in the Application Output tab.

*
* # 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.
