Force Click is a mikroBUS™ add-on board with circuitry for implementing Interlink Electronics’ Force Sensing Resistors into your projects (with a single zone force sensing resistor included with the Click). The Force Sensing Resistor is a thin sensor made of two membranes that are separated by a spacer around the edges.

Force Click is a mikroBUS™ add-on board with circuitry for implementing Interlink Electronics’ Force Sensing Resistors into your projects (with a single zone force sensing resistor included with the Click). The Force Sensing Resistor is a thin sensor made of two membranes that are separated by a spacer around the edges.
We provide a library for the Force 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 Force Click driver.
Config Object Initialization function.
void force_cfg_setup ( force_cfg_t *cfg );
Initialization function.
FORCE_RETVAL force_init ( force_t ctx, force_cfg_t cfg );
Click Default Configuration function.
void force_default_cfg ( force_t *ctx );
This function reads ADC data.
force_data_t force_generic_read ( force_t *ctx );
This function calculates resistance data based on the ADC input.
float force_get_resistance ( uint32_t adc_value );
This function calculates the correction factor based on temperature and humidity data.
force_get_correction_factor ( float temperature, float humidity );
This example showcases how to initialize and configure the logger and Click modules and read and display ADC voltage data read from the analog pin.
The demo application is composed of two sections :
This function initializes and configures the logger and Click modules.
void application_init ( )
{
log_cfg_t log_cfg;
force_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
log_printf( &logger, "--------------------\r\n" );
log_printf( &logger, " Force Click \r\n" );
log_printf( &logger, "--------------------\r\n\r\n" );
// Click initialization.
force_cfg_setup( &cfg );
FORCE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
force_init( &force, &cfg );
}
This function reads and displays ADC voltage data from the analog pin every second.
void application_task ( )
{
force_data_t tmp;
// Task implementation.
tmp = force_generic_read ( &force );
log_printf( &logger, " * ADC value : %d \r\n", tmp );
log_printf( &logger, "--------------------- \r\n" );
Delay_ms ( 1000 );
}
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.
