Title: DESIGN OF A USB-BASED DATA ACQUISITION SYSTEM
Abstract: Development of a multi-channel compact dataacquisition board, which collects real world analog (0-5 Volt dc) and digital data, delivers them to a personal computer using a USB communication link.The DAQ board is based on microchip PIC microcontroller (PIC18F2550).A GUI is developed on Visual Basic which displays the instantaneous analog and digital data.It can also be used for generating the control action signal (manual) which could be delivered to the actuator through a DAC through the microcontroller.
