Sports watch based on AVR (automatic voltage regulation) single chip microprocessor

Abstract

The invention relates to a sports watch based on an AVR (automatic voltage regulation) single chip microprocessor. The sports watch comprises a power supply module, a sports detection module, an AVR single chip microprocessor, a keystroke input module and an LCD (liquid crystal display) display module, wherein the power supply module is used for respectively powering the sports detection module, the AVR single chip microprocessor and the LCD display module, the sports detection module outputs detected data to the AVR single chip microprocessor, the AVR single chip microprocessor transmits a measuring result to the LCD display module to be displayed, and the AVR single chip microprocessor is externally connected with the keystroke input module. The frequency measurement is realized by utilizing an input capturing module of the AVR single chip microprocessor, physiological parameters can be relatively comprehensively acquired by a user, all the detected data are outputted to a peripheral device to be processed and analyzed, a reasonable exercise plane can be made, and the physical quality and the living quality can be effectively improved.

Description

technical field [0001] The invention relates to a watch, in particular to a sports watch based on an AVR single-chip microcomputer. Background technique [0002] Watches are mainly used for timing, but with the development of society, watches are endowed with more and more functions to meet the needs. Sports watches for sports and fitness have emerged as the times require. Current sports watches do not have large-capacity storage functions or data The transmission function can only record the information of daily exercise amount and display the currently detected physiological parameter value, and cannot store exercise amount and physiological parameter data for a long time. [0003] The on-chip EEPROM data memory of the AVR single-chip microcomputer exists as an independent data space, which can be read and written by byte. The life of the EEPROM is at least 100,000 erasing cycles. Contents of the invention [0004] In view of the above problems, the present invention ai...
