As an integrated modular solution, this application combines the traditional controller, driver, and arithmetic into one module, and it is also called a Black Box. The user only needs to be concerned about the interface without having to understand the circuit design and program architecture inside the box. This interface can adapt to the control by multiple hosts, such as PC, MCU, FPGA, and PLC. The box can complete more than 95% of the user’s work– the user only needs to deal with the remaining 5%. In this way, he can rapidly finish the system setup of the platform.

The desktop and imbedded contactless card reader mainly consists of the GD32F103 series MCU, NFC reading head chip, DCDC power chip, buzzer, and interface protocol conversion chip. It is mostly used in the all-purpose card for such scenarios as elevator control and management, filling machine, recreation park management, parking lot management, and micropayment management.

A micro-printer mainly refers to a printer with a width of less than 84mm. It can be a POS printer (commercial POS and financial POS), tax control printer, or the built-in or external micro-printer for such devices as ATM, ECR, and KIOSK. It is widely used in various industries, such as finance, retail, catering, lottery, transportation (including taxi, air ticketing, road and bridge toll), filling station, medical treatment and public health, postal service, utilities meter reading, mobile police system, and mobile government administration system.

In the automotive market, more and more customers are choosing to have vehicle driving recorders installed in their vehicles. In this recorder, the GD32 MCU has a strong application advantage. When the recorder is installed in the vehicle, the MCU will, by driving the GPS/Beidou module, access information about the vehicle’s current location and, through the GPRS module, send the location and driving information to the designated server for the user to query and use.

With the improvement of people’s living standard in China, sweeper robots originally sold in the U.S. and European markets have found their way into the homes of ordinary people, and they are affordable to more and more people. They will soon be an indispensable help to every family like white goods. Also, they will develop from a low level of intelligence to a higher one, gradually taking over manual sweeping.

As the serial port touch screen is developing from the original industrial application to the consumer world, many devices needing human-machine interfaces have to upgrade from the original monochrome dot matrix screen to the TFT color screen. The TFT color screen makes the pictures more colorful and vivid and interactions more effective, greatly improving the general competitiveness of a product.
