[Abstract]:Hand-held digital storage oscilloscopes are more and more widely used in field maintenance, installation and operation monitoring in the industrial and electronic fields. In order to facilitate communication with computers and peripherals, The interface communication of hand-held digital storage oscilloscope becomes the key link to extend its function. The communication of hand-held oscilloscope interface based on USB OTG technology has gradually become a hot spot in the application research of hand-held oscilloscope interface. The traditional oscilloscope USB interface communication uses the microcontroller control USB special chip to realize, the additional USB chip will increase the oscilloscope volume, In the design of DSO system, a microcontroller STM32F107VC integrated with USB OTG controller is used to realize the interface communication of USB OTG, which simplifies the hardware structure of the hand-held oscilloscope and highlights the portable characteristic of the hand-held oscilloscope. At the same time, the firmware library of STM series chips improves the efficiency of DSO system software development. Combined with STM32F107VC chip, in order to make the hand-held oscilloscope more practical and easy to operate, the 渭 C / OS- 鈪，
