- What is the difference with the old BBS motor?
- What does an e-bike’s driving feel depend on?
- What is the system’s communication protocol?
The communication protocol is a software standard between the system controller CPU and parts of the CPU, and also the platform of the standard’s implementation.
Current protocol platform: RS232, CAN, Lin-bus, I2C, 485, etc. The particular machine codes depend on the actual circuit design and appropriate communication. Each communication protocol’s effect is the same, transitive content is almost same.
