Instructions for Use

1. Power Supply:

   • Ensure the supply voltage is within the specified range of 2.4V to 5.5V.
   • Connect the VCC pin to the power supply and GND pin to ground.

2. Sensitivity Adjustment:

   • The sensitivity can be adjusted using the provided registers via the I2C or SPI interface.
   • Refer to the datasheet for specific register addresses and values.

3. Communication Interface:

   • Choose either I2C or SPI for communication with the microcontroller.
   • For I2C, connect SDA and SCL pins to the corresponding lines on the microcontroller.
   • For SPI, connect MOSI, MISO, SCLK, and CS pins to the corresponding lines on the microcontroller.

4. Initialization:

   • Initialize the sensor by sending the appropriate commands to configure the desired settings.
   • Ensure the sensor is properly configured before starting the detection process.

5. Detection:

   • The sensor will continuously monitor the touch area and send a signal when a touch is detected.
   • The output can be read through the communication interface.

6. Low Power Mode:

   • To enter low power sleep mode, send the appropriate command to the sensor.
   • The sensor will consume minimal current in this mode and can be woken up by a touch event or a command from the microcontroller.

7. Handling and Storage:

   • Store the sensor in a dry and cool environment to avoid damage.
   • Handle the sensor with care to prevent static discharge and physical damage.

For more detailed information, refer to the datasheet and application notes provided by the manufacturer.
