Introduction: USB to CAN low-cost solution
1. Product introduction
Although the USB to CAN solution currently on the market is very mature, it is also relatively expensive. The USB to CAN solution of this solution is low cost and easy to use. It requires no driver for WIn8 or above. Usage
2. Application scenarios
a: Used for communication between USB devices and CAN devices
b: Used as daily debugging tools for engineers
3. Product Overview
a: This solution can achieve two-way communication between USB devices and CAN devices
b: The principle is Between the USB device and the CAN device, the STM32F0 microcontroller is used for protocol analysis and forwarding. With the dedicated host computer software, you can use
c: The host computer adopts the winUSB driver-free solution and USB bulk double buffering mode. The actual transmission performance far exceeds those Virtual serial port USB-CAN
d: Flexibly choose whether to connect 120R terminal resistor through jumper cap
e: WIN8 or above system driver-free
