The thesis presents the research and analysis of the intelligent multi-function instrument based on low cost MCU. The technology point of the all-purpose signal measure, DAC based on PWM, lattice LCD display, key disposal, storage on serial FLASH, real time clock, communication on RS485 of hardware and digital filter, data disposal, digital PID control, system circulating display, system configuration, data storage and remembrance, real time clock of software are took apart and dissertated concretely. At last, the main structure design of the system software is introduced in general.
