ADI公司的AD7888是12位8通道高速串行模数转换器。本文详细阐述了AD7888的控制寄存器和接口时序,并给出了基于FPGA控制AD7888的硬件接口图和FPGA程序。该方法与CPU直接控制AD7888相比,实现起来较方便、灵活。 ADI’s AD7888 is a 12-bit, 8-channel, high-speed serial analog-to-digital converter. This article describes in detail the AD7888 control registers and interface timing, and gives the hardware interface based on FPGA control and AD7888 FPGA program. Compared with the direct control of the CPU by the AD7888, this method is more convenient and flexible to implement.
