The main differences between capacitive touch screen USB interface and capacitive touch screen IC interface are their communication protocols, transmission speeds and application scenarios.
The capacitive touch screen USB interface is a commonly used communication interface, designed for connecting computers and other devices, with the advantages of plug-and-play, no need to adjust driver data, and relatively fast transmission speed. It can be connected through OTG technology, and the capacitive touch screen module is connected to the main control board as a “slave”.
The capacitive touch screen IC interface, usually refers to the I2C interface, which is a serial communication protocol, using a two-wire system, can transmit data and clock at the same time, and is often used for communication between low-speed devices. The capacitive touch screen module communicates with the main control board through the I2C interface, and transmits data through the I2C bus.
In summary, the capacitive touch screen USB interface and the capacitive touch screen IC interface have differences in communication protocols, transmission speeds and application scenarios. Which interface to choose depends on the specific application requirements and product design.
How many interfaces does a capacitive touch screen have? Most people know that there are two types, IIC and USB. According to the product structure or host interface, the interface, structure and thickness of the touch screen you choose are determined. Some customers want a USB interface, but because the host or product interface or space is not enough to put the control card in it, they have to choose the capacitive touch screen with IIC interface. The IIC interface also has the advantages of the IIC interface. The USB interface capacitive touch screen is more convenient and simpler than the IIC interface. For example, it can be plug-and-play, does not require driver adjustment, and data transmission is faster than IIC.
