Sampling method for key data of point reading machine, storage medium, equipment and system

The invention discloses a sampling method for key data of a point reading machine, a storage medium, equipment and a system, relates to the technical field of touch detection, and solves the technical problems that the operation is complicated in the actual use process of the existing acquisition of the touch data of the point reading machine, and the sampled touch data is not accurate enough. The method comprises the following steps: when the point reading machine enters a data debugging mode, if an interrupt awakening instruction sent by a touch chip of the point reading machine is received, calling instant touch data in each data register; converting the instant touch data into an audio signal and outputting the audio signal to a loudspeaker of the point reading machine, and playing the instant touch data in the form of audio by the loudspeaker of the point-reading machine. According to the method, other equipment does not need to be disassembled, and the cost can be reduced while the sampling data accurac
