Library Description
The library carries a single function which allows complete control over GainAMP 2 click.
Key functions
gainamp2_writeCommand- Writes desired command data
Examples Description
The demo application shows the simplicity of usage.
The application is composed of two sections :
- System Initialization - Initializes CS pin as output and SPI module
- Application Initialization - Setups GainAMP 2 click channel 4 to amplify the signal 4 times
applicationInit()
{
gainamp2_spiDriverInit( (T_GAINAMP2_P)&_MIKROBUS1_GPIO, (T_GAINAMP2_P)&_MIKROBUS1_SPI );
// SETUP GAIN +4 on CHANNEL
gainamp2_writeCommand( _GAINAMP2_WRITE_INS | _GAINAMP2_CH, _GAINAMP2_CH4 );
gainamp2_writeCommand( _GAINAMP2_WRITE_INS | _GAINAMP2_GAIN, _GAINAMP2_GAIN_4X );
mikrobus_logWrite( "Channel 4 - aplified 4x", _LOG_LINE );
}
Additional notes and information
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.
