What is the difference between USB interface and IIC interface for capacitive touch screen?
Universal Serial Bus: The USB interface is a universal serial bus interface that supports hot-plugging and high-speed data transfer. In capacitive touchscreens, the USB interface is usually used to connect to a computer or other host device for data transfer and control of the touchscreen.
Inter-Integrated Circuit: The IIC interface, also known as I2C interface, is a serial communication protocol used to transfer data between integrated circuits. In capacitive touch screen, IIC interface is usually used to connect to microcontroller or other slave devices for touch data transmission and control.
Usually customers come to us to consult the capacitive touch screen programme when we will ask to IIC interface or USB interface, to choose which one is mainly to see the customer's motherboard support for what interface touch screen, mainly based on the definition of the motherboard, depending on the specific application requirements and device compatibility. We will provide you with the most suitable programme according to customer requirements.
