The existing intelligent metasurface electronic control systems fail to meet the rapid development requirements in terms of quantization accuracy, channel switching speed, adaptation for ultra-large arrays, and standard productization. This paper designs and implements a universal metasurface control system based on ZYNQ. The system consists of four sets of 128-channel high-precision programmable voltage output controllers cascaded together. A single controller utilizes the logic portion of ZYNQ to simultaneously control eight pieces of DAC, enhancing the switching speed. This setup enables independent voltage output for 128 channels, supporting continuous adjustable output voltage within the range of 0 to 20 V with an output accuracy 0.05 V and a response rate of less than 1.5 ms. By cascading the four sets of controllers, 512 channels of voltage output are achieved, facilitating intelligent metasurface dynamic control based on preset voltage encoding. Experimental results demonstrate that this control system meets the design specifications, offering high output accuracy, fast response speed, a high number of channels, and flexible, convenient usage, meeting the demands of intelligent metasurface control.
