1 Introduction to D133CBV-QFN88-V1-2 Development Board

D133CBV-QFN88-V1-2 is a human-computer interaction application development board based on the D13x (RISC-V core) chip design. It is equipped with a 7-inch LVDS display and a capacitive touch screen, and also has reserved MIPI screen and resistive touch screen interfaces. The development board integrates debugging interfaces such as USB burning, TF-Card upgrade burning, JTAG, and serial port printing, which is convenient for debugging and development. The development board integrates 16MB NOR FLASH and is compatible with NAND. It also leads to USB Host, CAN, RS485, SDIO WIFI, Ethernet, Speaker, digital MIC, buzzer and other functions, and reserves I2S, I2C, UART and other interfaces, which facilitates users to quickly conduct technical pre-research and product development, and meet users' development needs for different human-computer interaction scenarios.

2.1 Power supply debugging interface

• P1 Type-C interface, USB Device can be used for burning upgrades and power supply. J19 is the USB-SW switch jumper, the default NC means the USB is the Device function (P1), short-circuited means the USB switches to the Host function (J21)
  
  
  
• J1 5Pin curved socket, UART0 debug printing serial port, can be used to print debug information.

2.2 Use

Use Type-C for power supply, use USB to TTL to connect to UART0, then open the terminal assistant, the baud rate is 115200, and the printed information is as follows.

At the same time, the LCD will display.

Well, this is the basic use of the D133CBV-QFN88-V1-2 development board.
