Data transmission method and data transmission device

摘要

A data transmission method capable of suppressing communication errors with a simple microcomputer processing is provided. Upon a pulse signal in which specific data is made up of H and L levels, either one of which has a pulse width taken as a first fundamental signal length T1 and the other of which has a pulse width taken as a second fundamental signal length T2 equal to an integer multiple of the first fundamental signal length T1, a correction is performed by increasing or decreasing the second fundamental signal length T2 by a length equal to an integer multiple of a value resulting from dividing the first fundamental signal length T1 of the transmission-side pulse signal by an integer.
