TouchPad 4 Click Board
TouchPad 4 Click Board
The TouchPad 4 Click Board™ is a compact add-on board that easily integrates projected capacitive touch into your projects. This board features the IQS7211A, a tiny capacitive touch controller from Azoteq. A low-power dedicated wake-up touch controller launches a complete touchscreen sensing solution with a 25.4 x 29mm trackpad dimension, best-in-class sensitivity, and power consumption. It is characterised by embedded gesture engine recognition for simple gestures (tap, swipes, hold) and built-in noise detection and filtering.
The TouchPad 4 Click Board™ is suitable for human-machine interfaces, keypad or scrolling functions, single-finger gesture-based interfaces, and more.
Software Support
We provide a library for the Touchpad 4 Click and a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on the MikroE Github account.
Library Description
This library contains an API for the Touchpad 4 Click Board™driver.
Key Functions
touchpad4_cfg_setup
- Config Object Initialization function.touchpad4_init
- Initialization function.touchpad4_default_cfg
- Click Default Configuration function.
Example Description
This example showcases the ability of the device to read touch coordinates, active/inactive channels, and gesture information.
void application_task ( void ) { if ( !touchpad4_get_ready( &touchpad4 ) ) { switch ( example_selector ) { case TOUCHPAD4_EXAMPLE_TOUCH: { touchpad4_touch_reading( ); break; } case TOUCHPAD4_EXAMPLE_CHANNEL: { touchpad4_channel_reading( ); break; } case TOUCHPAD4_EXAMPLE_GESTURE: { touchpad4_gesture_reading( ); break; } default: { log_error( &logger, " Select Example" ); break; } } } } The complete application code, and ready-to-use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on the MikroE Github account.
Other mikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.Touchpad4
Additional Notes and Information
Depending on the development board you are using, you may need a USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ 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
The Touchpad 4 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.
