Cap Extend click is a mikroBUS add-on board with a SEMTECH SX8633 low power, capacitive button touch controller. It has 12 pins for connecting capacitive inputs (either touch-buttons or proximity sensors).
We provide a library for the CapExtend 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 CapExtend Click driver.
void capextend_cfg_setup ( capextend_cfg_t *cfg );
CAPEXTEND_RETVAL capextend_init ( capextend_t *ctx, capextend_cfg_t *cfg );
void capextend_default_cfg ( capextend_t *ctx );
void capextend_reset ( capextend_t *ctx );
int8_t capextend_read_msb_buttons ( capextend_t *ctx );
int8_t capextend_read_lsb_buttons ( capextend_t *ctx );
This example showcases the initialization and configuration of the logger and click modules
and later on shows how to read and display the 16-bit button map ( LSB + MSB ).
The demo application is composed of two sections :
This function initializes and configures the click and logger modules.
This function collects map data and displays the 16-bit button map, where each bit that has
the value 1 represents a button that has been pressed.
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.
