| Abstract: | Data acquisition system based on USB (Universal Serial Bus), In order to guarantee the normal working of EZ-USB and correspond with PC, its peripheral circuits contain the interface between EZ-USB and PC, as well as current circuit. Software contains firmware design (pretreatment), driver and PC application program. The data is sent to A/D through conditioning circuit, and then it is sent into PC by FIFO buffer through EZ-USB. After algorithm conversion, the D/A conversion outputs analog signal to carry out real-time control. |
