The application relates to a visual digital coding metasurface antenna control circuit which comprises a core control board, a port driving board and a state indicating board; the core control board is connected with the port driving board in the form of plugging, and the port driving board is connected with the state indicating board. The core control board adopted by the application improves the load driving capacity of the output port of the core control board through the port driving board, and then expands the output port with improved load capacity into multiple output ports through the state indicating board, thereby leaving an expansion space for constructing a larger scale digital coding metasurface antenna; the core control board transmits antenna control signals to the antenna through the multiple output ports, so as to control the on-off of the radio frequency switch in the antenna, realizes the digital programming control of the radio frequency switch of the digital coding metasurface antenna, and displays the on-off state of the radio frequency switch in the form of light on-off through the state indicating board, thereby achieving the purpose of visually displaying the real-time state of each radiation unit phase.
