c2x20wamp 2.0.0.0
|
2x20W Amp click carries the MAX9744 stereo class D audio power amplifier from Maxim Integrated. This click brings the Class AB sound performance with Class D efficiency.
We provide a library for the c2x20WAmp 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for c2x20WAmp Click driver.
- Initialization function.void c2x20wamp_cfg_setup ( c2x20wamp_cfg_t *cfg );
C2X20WAMP_RETVAL c2x20wamp_init ( c2x20wamp_t *ctx, c2x20wamp_cfg_t *cfg );
- Set volume of the amplifier function
void c2x20wamp_set_volume( c2x20wamp_t *ctx, uint8_t volume );
This application changes the volume level.
The demo application is composed of two sections :
>Initialization driver enable's - I2C, start write log and enable amplifire of 2x20W Amp Click board.
>This is a example which demonstrates the use of 2x20W Amp Click board. This examples first activates operation mode PLAY and set volume lvl 32 ( 50% ), after that, we increase the volume level one level ten times for 5 seconds and we decrease the volume level one level ten times for 5 seconds. And finally, we set MUTE mode for next 5 seconds. Results are being sent to the Usart Terminal where you can track their changes.
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
