AI Technical Summary

Problems solved by technology

[0005] When the above-mentioned existing asynchronous receiving transmitter receives, it can only be obtained by reading twice group by group, which increases the workload of the microprocessor B and reduces the efficiency. , Microprocessor B cannot have extra efficiency to handle other tasks or reduce the processing speed, which makes users feel inconvenient

Embodiment Construction

[0034] In order to achieve the above purpose and effect, the technical solution and structure adopted by the present invention are as described above, and the features and functions of the preferred embodiments of the present invention will be described in detail as follows according to the accompanying drawings, so as to facilitate a complete understanding.

[0035] see Figure 8 As shown, it is a schematic flow chart (1) of the method for reading data by an asynchronous receiver of the present invention. It can be clearly seen from the figure that the asynchronous receiver transmitter (Universal Asynchronous Receiver Transmitter) 1 has a receiver shift register (Receive Shift Register) 11 , receiving register (Receive Register) 12 and counter 13; Wherein:

[0036] The receiving shift register 11 can receive serial data, and the serial data includes a start bit, a stop bit and a data bit, and can transmit the serial data to the receiving register 12 .

[0037] The receiving ...

Abstract

This invention relates to a receiving method by synchronous receivers, in which, the asynchronous receiving transmitter includes a shift register and a computer, the receiving shift register is connected with the receiving register connecting to a preset microprocessor via the bus, when the register receives the serial data sent by the shift register, the computer computes the correct data volume labeled in the error bit, so that the microprocessor takes the number computed by the computer as the times of reading data address by the microprocessor to read all labeled correct data to increase the read efficiency.

Description

technical field [0001] The invention relates to a receiving method of an asynchronous receiver, in particular to a receiving method which uses a counter set in the asynchronous receiver to calculate the correct amount of data to improve reading efficiency. Background technique [0002] The original meaning of communication refers to the communication of opinions or the exchange of information, but modern communication also includes the transmission of multimedia information such as audio, video and text to remote means by wireless or wired means. From a technical perspective, it refers to After encoding and modulating various signals, they can still be efficiently, safely and successfully transmitted to distant places. Using the "electricity" transmission function, you can quickly and conveniently watch TV, make phone calls, listen to radio programs, and transmit Files can also be sent or received via the network via a telephone line or cable TV cable using a modem, browsing...
