Library contains function for waiting RDY(INT) pin Library contains function for getting RDY(INT) pin state Library contains function for I2C read and write with waiting for RDY(INT) pin Library contains function for I2C read and write without waiting for RDY(INT) pin Library contains function for setting basic device configuration

Key functions:

  • uint8_t capwheel2_i2c_write_wait( uint8_t register_address, uint8_t * register_values, uint8_t n_bytes ) - waits for RDY pin to go from HIGH to LOW in order to set register contents.
  • uint8_t capwheel2_i2c_read_wait( uint8_t register_address, uint8_t * read_buffer, uint8_t n_bytes )- waits for RDY pin to go from HIGH to LOW in order to get register contents.
  • uint8_t capwheel2_config(void)- checks device information and sets basic device configuration, thresholds and sensitivity values.

Examples description

The application is composed of three sections :

  • System Initialization - systemInit( ) - Initializes I2C, LOG and INT pin
  • Application Initialization - applicationInit( ) - Initializes I2C driver and CAP Wheel 2 device
  • Application Task - applicationTask( ) - Executes one of three 'capwheel2_get_xxx_task( )' functions

Additional Functions :

  • capwheel2_error( ) - Logs error message and blocks code execution in endless while loop
  • capwheel2_get_channels_task( ) - Logs active channels in touch and halt bytes ( channels: CH0 - proximity channel, CH1, CH2, CH3 )
  • capwheel2_get_gesture_task( ) - Logs active gestures ( gestures: tap, touch, proximity )
  • capwheel2_get_channel_counts_task( ) - Logs channel count values for each channel
  • capwheel2_get_channels_touch( ) - Logs touch byte active channels ( exectuted by 'capwheel2_get_channels_task( )' function )
  • capwheel2_get_channels_halt( ) - Logs halt byte active channels ( exectuted by 'capwheel2_get_channels_task( )' function )
  • capwheel2_error( ) - Logs error message and blocks code execution in endless while loop
  • capwheel2_get_channels_task( ) - Logs active channels in touch and halt bytes ( channels: CH0 - proximity channel, CH1, CH2, CH3 )
  • capwheel2_get_gesture_task( ) - Logs active gestures ( gestures: tap, touch, proximity )
  • capwheel2_get_channel_counts_task( ) - Logs channel count values for each channel
  • capwheel2_get_channels_touch( ) - Logs touch byte active channels ( exectuted by 'capwheel2_get_channels_task( )' function )
  • capwheel2_get_channels_halt( ) - Logs halt byte active channels ( exectuted by 'capwheel2_get_channels_task( )' function )
void applicationTask( )
{
    capwheel2_get_channels_task( );
}

The full application code, and ready to use projects can be found on our LibStock page.

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

Angle Click

0

Angle Click is a precise Hall-effect angle sensing Click board that can be used to measure the rotational angle of the magnetic field in the X-Y plane above it (parallel to the surface of the Click), through the whole range of 360°.

ROTARY Y Click

0

Rotary Click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 yellow LEDs. It’s a perfect solution for adding a precision input knob to your design. The encoder outputs A and B signals (out of phase to each other); the knob also acts as a push-button which sends an interrupt to the target board MCU. The LED ring is controlled through SPI lines (CS, SCK, MISO, MOSI). Rotary Click can be used with either a 3.3V or 5V power supply.

Speed Sense Click

0

Speed Sense Click is a compact add-on board that allows you to measure the speed and rotation of a spinning object. This board features the A17501, a dual output differential speed and direction sensor from Allegro Microsystems. It has a high-speed switching bandwidth of up to 40kHz for two different signals. The sensor has two independent output channels with options for high-resolution XOR speed, pulse, and direction protocol.
