Library Description

The library covers all the necessary functions to control Force 2 click board.

Key functions:

• force2_adc_set_in_channel( ); - Function sets input channel.
• force2_adc_init( ); - Function initializes ADC.
• force2_adc_read( ); - Function reads ADC values.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO and LOG structures, set AN pin as input.
• Application Initialization - Initalizes ADC driver, sets ADC channel and makes an initial log.
• Application Task - (code snippet) This is an example that shows the capabilities of the Force 2 click by taking measurements from the device and displaying it via USART terminal.

void application_task ( )
{
    adc_val = force2_adc_read( );
    disp_val = force2_val_conv( adc_val, 4095, 15, 0 );
    
    ByteToStr( disp_val, log_txt );
    Ltrim( log_txt );
    mikrobus_logWrite( "Force: ", _LOG_TEXT );
    mikrobus_logWrite( log_txt, _LOG_TEXT );
    mikrobus_logWrite( "N", _LOG_LINE );
    
    mikrobus_logWrite( "-------------------", _LOG_LINE );
    Delay_ms( 500 );
}

• force2_val_conv ( uint32_t x, uint32_t in_max, uint32_t out_min, uint32_t out_max ) - re-maps ADC value to force value in newton.
• force2_adc_set_in_channel( ); - Function sets input channel.
• force2_adc_init( ); - Function initializes ADC.
• force2_adc_read( ); - Function reads ADC values.
