Abstract
The paper proposes a dual trace digital storage oscilloscope which is based on the Linux2.4 core and S3C2410. With the adder circuit consisted of OPA2604 and sample hold devices LF398, it is a good solution to the problem of two-channel signal synchronization of the digital oscilloscope for the data acquisition and display. And the paper will give a detailed description about the design of interface of LCD display and ADC data acquisition on the hardware circuits. It discusses software design method about data sampling, display drive etc. It uses multithread and read-write spin lock mechanism that can be a great improvement for the executing efficiency of program. Some examples are given.
