| Abstract: | This article describes a 16-channel portable logic analyzer.Sampling is performed through the FPGA and high-speed data buffer,the data is sent to the computer via the USB controller chip and FPGA cooperative control through the USB interface on the PC display,thus simplifying the previous circuit logic analyzer hardware and reducing the cost and size of the logic analyzer.Emphasis is put on the hardware circuit design. |
