ARM,namely advanced RISC microprocessor (advanced RISC). This paper takes the application of PHILIPS LPC2119 in the strain measurement system as an example,introduces the design of electric bridge and signal adjusting circuit,uses the A/D converter to realize the conversion of input voltage and output voltage of the electric bridge,uses the system program to realize electric bridge automatic zero adjust and automatic range switching,and introduces the interface and external resource expansion function of LPC2119.With these methods,the system integration degree is improved and the system structure is simplified.
