[Training Camp_Basic Class] USB3.0 hub design based on C69417 +636382A

Overview

Functions: 1. Use USB3.0 square port male data cable to connect to the computer, expanding the USB interface; 2. There are power indicator lights and each interface indicator light; 3. Firmware can be downloaded to SPI, no need to power on every time The firmware needs to be downloaded manually; 4. The DC-JACK power interface is expanded, and 5V power supply can be input; Description: 1. Using VL812’s C69417 as the main control chip, it integrates 5V-3.3V and 5V-1.2V circuits, which can reduce peripheral circuit; 2. A common mode inductor and TVS tube are added to the USB3.0 interface, which are used for EMI filtering and anti-static respectively; 3. The 5V input has a fuse to prevent the circuit from being burned; 4. The PCB is designed with a regular hexagon corresponding to six Interfaces (1 power input, 1 USB input, 4 USB interfaces).

Multiple external interrupt source system design
Multiple external interrupt source system design The standard 8051 provides users with two external interrupt request input terminals INT0 and INT1 . In actual application systems, two external interr
This is how to distinguish between active and passive devices? What do you think?
The "source" of active devices and passive devices refers to the "driving source" or "driving source", but this "source" often comes from the "power supply" for electronic devices, so there will be mi
