Abstract

The invention discloses a sensor data read-write device and a read-write method thereof. Data export and system parameter configuration of most electronic systems with high professionality often needto be realized by means of matched upper computer software. The invention discloses a sensor data reading and storing circuit which comprises a power circuit, a multiplexing circuit, a TF card circuit, a TF card reading circuit and a main control circuit. The TF card reading circuit comprises a card reader chip and a USB socket. The multiplexing circuit includes a multiplexing chip. By arranging the multiplexing circuit, the TF card can be switched and connected with the main control chip and the upper computer, so that the reading process of sensor data and the configuration process of the sensor are simplified. A data selection end of the multiplexing chip is connected to a TF card reading circuit. Therefore, when the TF card reading circuit is powered on, the TF card is automatically connected with the upper computer, and the process of connecting the TF card with the upper computer is simplified.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a sensor data reading and writing device and a reading and writing method thereof. Background technique [0002] Data storage and system parameter configuration are important components of various embedded electronic systems. The data export and system parameter configuration of most professional electronic systems often need to be realized with the help of supporting host computer software. The development of the supporting dedicated upper computer software needs a certain amount of energy and financial resources, and the incompatibility of the upper computer will cause inconvenience to users. Therefore, it is particularly important to develop a data storage and parameter configuration circuit with good versatility, strong operability and easy use in the design of electronic systems. Contents of the invention [0003] The object of the present invention is t...
