CIR24TFT29 Application Field and Working Principle

CIR24TFT29 is a recently developed industrial control system operating with the assistance of touch screen technology. The system comprises a multifunctional TFT (Thin Film Transistor) touch panel, an embedded microcomputer or microcontroller-based circuit, a DC power supply module, and a bridge IC (integrated circuit) to connect the two. This system is highly suitable for use in various industrial applications, such as industrial robots, embedded computer systems, industrial process control, industrial sensing, industrial automation systems and touch detection.The CIR24TFT29 system uses an ST651 UART, which provides a link between the microcontroller and the TFT panel, and allows the microcontroller to communicate with the panels. It also uses a FT8332D DC/DC converter to power the TFT panel. This DC/DC converter helps to reduce power consumption. A OEG400 bridge IC is used to link the TFT panel and the DC/DC converter. The FT8332D also provides a bridge between the TFT panel and the microcontroller.The CIR24TFT29 consists of two main parts: the touch panel and the embedded microcomputer. The embedded microcomputer runs on a 32-bit ARM processor and consists of a digital signal processor (DSP), which is used for signal processing and calculations, and an ATmega128 system, which is responsible for all low-level I/O operations.The TFT panel, on the other hand, uses a capacitive sensing technology that detects small capacitance changes due to human touch on the screen surface. The panel has five scan lines for touch detection. Each scan line has a two-dimensional coordinate system and each point on the panel\'s coordinate system can be assigned a unique address. The CIR24TFT29 also includes an additional 12-bit timing counter to measure the duration of contact. This allows the system to detect exactly when contact is made with the panel.The main application field of the CIR24TFT29 is industrial automation. It is used in a wide range of industrial applications such as robotic assembly carried out by industrial robots, industrial machine tools, industrial process control, and industrial sensors and feedback systems. It is also used in embedded computer systems, where it is used to create an interface between the embedded computer system and the TFT panel.The CIR24TFT29 system works with three main principles. First, it uses capacitive sensing technology for touch detection. Second, it uses the ST651 UART for communication between the microcontroller and the TFT panel. Third, it uses the FT8332D DC/DC converter to reduce power consumption. These three principles come together to create a reliable and low cost touch panel system that can be used in a variety of industrial applications.
