Problems solved by technology
The sampling task requires a certain time limit, and in the high-speed communication scenario, if the frame interval of the communication is less than the set period of the target sensor output, it will appear. If the central processing unit stores the sampled data into the A register and receives After receiving the data acquisition request sent by the host computer, directly reading and uploading the A register will result in repeated or incomplete uploaded data

The invention provides a method for sampling and storing data in an encoder, a single chip microcomputer and a storage medium. The method comprises the steps that a central processing unit circularly executes a first instruction set; the first instruction set comprises a first subset and a second subset; when the first subset is executed, the central processing unit samples first data output by the target sensor successively, and the first data are stored in the first register; when the second subset is executed, a first target register is determined according to the current execution frequency of the first instruction set, first data in the first register is sent to the first target register, and the first register is emptied; in response to a received data acquisition request sent by the upper computer, determining a second target register according to the current execution times of the first instruction set; and sending the address pointer of the second target register to the DMA module, so that the DMA module reads the first data in the second target register, and sends the read first data to the upper computer.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a method for sampling and storing data in an encoder, a single-chip microcomputer and a storage medium. Background technique [0002] During the working process of the encoder, it is necessary to sample and store the output data of the position sensor, and in response to the request of the host computer, send the sampled data to the host computer, so that the host computer can monitor the position of the motor corresponding to the encoder. The working status is displayed. [0003] If the encoder uses a single-chip microcomputer to perform target sensor sampling and communication transmission, since the single-chip microcomputer is single-core, the sampled data cannot be directly sent to the host computer, but the first data obtained by sampling needs to be stored first. After receiving the data acquisition instruction, store and upload the first data in the register. However, sin...
