Abstract

The invention discloses a measuring tool platform and a measuring method based on an AVR (automatic voltage regulator) singlechip. The measuring tool platform comprises ten main modules as follows: a minimum system module, a keyboard module, an AD (analog-to-digital) module, a DA (digital-to-analog) module, a serial communication module, a temperature measuring module, an infrared receiving block, a display module, a drive module, a power source module and a clock module; corresponding control I / O (input / output) ports are distributed to the modules by a system board; and each module is connected with the singlechip by adopting a wire jumper manner. The measuring tool platform based on the AVR singlechip has the characteristics of being convenient to carry, capable of clipping functions and volume, and suitable for popularization and application.

Description

Technical field [0001] The invention relates to a measurement tool platform, and specifically to a measurement tool platform and a measurement method based on an AVR single-chip microcomputer. Background technique [0002] The AVR microcontroller is designed by ATMEL Corporation of the United States. The AVR microcontroller has made a major transformation to the original 51 microcontroller core, abolishing the machine cycle in the original 51 microcontroller, and improving from the original 12 clocks to execute one instruction to one clock cycle to execute a single cycle Instruction, the number of clock cycles required to execute most instructions is the same as the number of bytes of the instruction, which greatly improves the operating speed of the AVR microcontroller. [0003] AVR also integrates Flash, EEPROM, A / D, RTC (real-time system), WatchDog, timer, I2C, SPI, PWM, and on-chip oscillator, which can be truly monolithic. The AVR microcontroller is compatible with 51 instruc...
