Problems solved by technology

[0004] The traditional UART contains two problems: 1. RX (receiving end), TX (sending end), GND, 5V, 4 wires, the wiring harness is relatively complicated and one more wire will increase a point of failure, affecting the stability of program upgrades
2. The communication is different frames, and it is necessary to wait for an interval of more than 20ms after sending a frame before sending the next frame
This method requires a period of time between frames, so the communication bandwidth utilization rate is only 10% or even lower, and the program update time is longer

Abstract

The invention discloses a single-line UART efficient communication method. According to the technical scheme, a controller, a controller counterpoint computer and a communication line for connecting the controller and the controller counterpoint computer are included. The method comprises the following specific steps: S1, storing total data between a controller and a controller counterpoint computer; S2, obtaining tail data in the total data; S3, acquiring the data length in the total data; S4, searching other data according to the data length based on the tail data; S5, verifying other data: when the other data are correct, the data are valid data of one frame, and when the other data are wrong, the data are invalid data, the efficient communication method can improve the communication bandwidth utilization rate, and the purpose of more stable and rapid program upgrading is achieved.

Description

technical field [0001] The invention relates to a communication method, more specifically, it relates to a single-line UART high-efficiency communication method. Background technique [0002] In today's electric bicycles, scooters and other products, user needs are becoming more and more diverse and personalized. Therefore, in the process of using the product in the later stage of the user, it is often necessary to update the software to meet the diverse and personalized needs of the user. [0003] Because software updates are becoming more and more frequent, softening the update time is becoming more and more important to the user's product experience. Stable and fast upgrade procedures will bring customers a good product experience. [0004] The traditional UART contains two problems: 1. RX (receiving end), TX (sending end), GND, 5V, 4 wires, the wiring harness is relatively complex and one more wire will increase a point of failure, affecting the stability of program up...
