Portable digital temperature compensating type crystal oscillator chip reader-writer and reading/writing method thereof

Abstract

The invention relates to a portable digital temperature compensating type crystal oscillator chip reader-writer and a reading / writing method thereof. The reader-writer comprises an MCU (Micro Control Unit) core control module (1) respectively connected with a crystal oscillator chip based on an I2C bus, a keyboard operation module and an information display module and used for exchanging data with the crystal oscillator chip and reading / writing the parameter of a register of the crystal oscillator chip through an I2C protocol and uniformly controlling the keyboard operation module and the information display module, a keyboard operation module (2) used as an operation end of the whole reader-writer and used for selecting each operation and inputting data, and an information display module (3) used for displaying the real-time operation information and the parameter of the temperature compensating type crystal oscillator chip. The reader-writer further comprises a computer control module used for expanding the function of the reader-writer and connected with the MCU core control module via an RS232 communication interface. Compared with the prior art, the invention has the beneficial effect of developing a portable device capable of conveniently reading / writing the register of a digital temperature compensating type chip. Through the invention, the data of the register of the chip can be instantly displayed so as to bring convenience to the operation of a user; the reader-writer and the reading / writing method thereof have the functions close to that of industrial production equipment so as to bring convenience to the development and the debugging of a few products; and meanwhile, the energy consumption is low and the occupancy and the dependence on large scale equipment are decreased.

Description

technical field [0001] The invention relates to a read-write device and a read-write method. It is mainly used in the R&D and debugging stages of the digital temperature compensated crystal oscillator (hereinafter referred to as DTCXO), and reads and writes the parameters of the IX2204 digital temperature compensation chip based on Innosign. Background technique [0002] In the production of DTCXO, the most important step is to correct the internal register parameters of the digital temperature compensation chip used by it, so that the produced DTXO can meet the production standard. General production equipment has hundreds of debugging positions. In the production stage, it can quickly mass produce products that meet the standards. However, it is a great waste to use mass production equipment during research and development and single debugging. For actual operation That said, it's also very inconvenient. Contents of the invention [0003] The technical problem to be so...
