DC1962C is an evaluation and demonstration board from Texas Instruments. It is used to evaluate and demonstrate the capabilities of the E2E capacitive touch sensing technology from Texas Instruments. The DC1962C board is capable of detecting the presence and location of a touch contact in proximity to its electrodes. By detecting a touch, the DC1962C can be used for application field, such as touch buttons, sliders, or keypad. It is based on the MSP430 microcontroller, and includes an analog-to-digital converter (ADC), capacitive touch-sensing circuitry, and UART/I2C interfaces for communication with a PC or other devices.

Working Principle

The DC1962C board utilizes the properties of direct capacitance touch sensing. The board has eight general-purpose input/output (GPIO) pins connected to sensing electrodes on a PCB and four GPIO pins connected to a reference electrode. When the sensing electrodes are touched, the capacitance between the sensing and reference electrodes increases. This increased capacitance is detected by the DC1962C board and communicated to the microcontroller. The DC1962C board also contains an on-board hardware amplifier and timing capacitor, which help to reduce noise and improve sensitivity.

The DC1962C board can detect a single touch or multiple touches in its contact area. When connected to a PC or other device, the DC1962C board can communicate the locations of the touches to the PC or other device for further action. The DC1962C board also has provisions for enabling and disabling the touch-sensing circuitry, calibrating the electrodes, and setting the sensitivity of the touch-sensing circuitry. This allows the DC1962C board to be used in a wide range of applications.
