We provide a library for the VUMeter Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for VUMeter Click driver.
vumeter_cfg_setup
Config Object Initialization function. vumeter_init
Initialization function. vumeter_read_an_pin_voltage
This function reads results of AD conversion of the AN pin and converts them to proportional voltage level. vumeter_set_gain_level
This function sets the input signal gain level (the microphone sensitivity). vumeter_calculate_vu_level
This function calculates VU level from the analog voltage input. This example demonstrates the use of VU Meter click board.
The demo application is composed of two sections :
Initializes the driver and sets the gain level (the microphone sensitivity) to maximum.
Calculates VU level from the analog voltage read from AN pin, and displays the results on the USB UART approximately every 100ms.
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
Other Mikroe Libraries used in the example:
Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
