Cap Touch 5 Click Board
Cap Touch 5 Click Board
The Cap Touch 5 Click Board™ is a capacitive touch sensing Click Board™ that features the CY8CMBR3106S-LQXI CapSense® Express™ controller which enables advanced, yet easy-to-implement, capacitive touch sensing user interface solutions. It supports up to 16 capacitive sensing inputs, eliminates time-consuming firmware development. This controller is ideal for implementing capacitive buttons, sliders, and proximity sensing solutions with minimal development-cycle times.
The Cap Touch 5 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
Software Support
We provide a library for the CapTouch 5 Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library covers all the necessary functions to control the Cap Touch 5 Click Board™.
Key Functions
void captouch5_config_sensors( uint16_t sens_data )
- Function for configuring sensor.void captouch5_config_slider( uint8_t slider_data )
- Function for configuring slider.void captouch5_read_button_status( T_CAPTOUCH5_BUTTONS *buttons )
- Function read button status.
Example Description
The application is composed of three sections :
- System Initialization - Initializes I2C module
- Application Initialization - Initializes driver init, tests communication and configures the device
- Application Task - Waiting for touch sensor to detect something and then logs what is touched
void applicationTask( ) { uint16_t temp_byte; uint16_t last_temp; uint8_t error_data; uint8_t temp_slider; state_check = 0; error_data = captouch5_process( ); if ( error_data == CAPTOUCH5_ERROR ) { mikrobus_logWrite( "***** ERROR *****", _LOG_LINE ); mikrobus_logWrite( " ", _LOG_LINE ); mikrobus_logWrite( " ", _LOG_LINE ); state_check = 1; return; } temp_byte = captouch5_read_slider_position( ); captouch5_read_button_status( &buttons ); if ( temp_byte != last_temp ) { mikrobus_logWrite( "Slider position value: ", _LOG_TEXT ); WordToStr( temp_byte, demo_text ); mikrobus_logWrite( demo_text, _LOG_LINE ); mikrobus_logWrite( " ", _LOG_LINE ); mikrobus_logWrite( " ", _LOG_LINE ); last_temp = temp_byte; state_check = 1; } captouch5_read_buttons( ); Delay_ms ( 100 ); if ( state_check == 1 ) { mikrobus_logWrite( "--- Waiting for command ---", _LOG_LINE ); mikrobus_logWrite( " ", _LOG_LINE ); mikrobus_logWrite( " ", _LOG_LINE ); } }
Additional Functions :
- _captouch5_readButtons() - Logs button press
- _captouch5_deviceConfig() - Configures device
Note :
- Click will go to sleep if doesn't get any command in 340ms
- When you start the device try restarting your board few times to start the device
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- I2C
- UART
- Conversions
Additional Notes and Information
Depending on the development board you are using, you may need a 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.
mikroSDK
This Click board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
