Research on ARM Communication Management Based on Dynamic Cache

The ARM-based communication management has the advantages of low cost, flexible, efficient and applicable, and widely used. Aiming at the problem of probabilistic remote control failures at low baud rate in the running of the equipment, a method of dynamically adjusting the sender-cache based on the serial baud rate is proposed in this paper, which has improved the remote control success rate in the way of optimizing cache sending time. This method turns out to be stable and reliable, and has a good effect in the running of the equipment.
