Cap Wheel 2 click

CAP Wheel 2 Click is a capacitive touch sensor with round-shaped electrodes integrated on a Click board™. This click can sense touch even through plastic, wood, or other dielectric materials, which can be used to protect the surface of the PCB and the sensor pad trace itself. Therefore, this Click board™ comes with overlay, made of plexiglass. Unlike the mechanical button, the capacitive touch button lasts much longer, it is not prone to damage and wear over time and it is very reliable. This Click board feature QS263B sensor which contains a ProxSense® module that uses patented technology to provide detection of proximity and touch conditions on numerous sensing lines.

Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the CapWheel2 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.

Library Description

‍This library contains API for CapWheel2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    ‍void capwheel2_cfg_setup ( capwheel2_cfg_t *cfg );

    - Initialization function.

    ‍CAPWHEEL2_RETVAL capwheel2_init ( capwheel2_t *ctx, capwheel2_cfg_t *cfg );

  • Click Default Configuration function.

    ‍void capwheel2_default_cfg ( capwheel2_t *ctx );

Example key functions :

  • This function gets state of INT pin.

    ‍uint8_t capwheel2_int_get ( capwheel2_t *ctx );

    - This function waits for RDY pin to transition from HIGH to LOW state.

    ‍uint8_t capwheel2_wait_for_rdy ( capwheel2_t *ctx );

    Examples Description

‍This example sets basic device configuration; Contains function for waiting RDY(INT) pin, function for getting RDY(INT) pin state, function for I2C read and write with waiting for RDY(INT) pin and without waiting for RDY(INT) pin.

The demo application is composed of two sections :

Application Init

‍Initializes CAP Wheel 2 device

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
CAPWHEEL2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
capwheel2_init( &capwheel2, &cfg );
}
#define CAPWHEEL2_MAP_MIKROBUS(cfg, mikrobus)
Definition: capwheel2.h:53
void capwheel2_cfg_setup(capwheel2_cfg_t *cfg)
Config Object Initialization function.
CAPWHEEL2_RETVAL capwheel2_init(capwheel2_t *ctx, capwheel2_cfg_t *cfg)
Initialization function.
void application_init(void)
Definition: main.c:302
Click configuration structure definition.
Definition: capwheel2.h:135

Application Task

‍Executes one of three 'capwheel2_get_xxx_task( )' functions.

void application_task ( void )
{
}
void application_task(void)
Definition: main.c:327
void capwheel2_get_channels_task()
Definition: main.c:236

Note

 
Additional Functions :


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.
Other mikroE Libraries used in the example:
  • MikroSDK.Board
  • MikroSDK.Log
  • Click.CapWheel2
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.
