摘要
根据数字微镜装置DMD的显示特性,以FPGA芯片为核心,设计了一种DMD驱动控制方案;从微镜的工作过程和二进制脉冲宽度调制理论入手,阐述了在有限利用TI公司相关芯片的情况下自主开发设计驱动控制电路的原理和整体方案,详细分析了包括图像解码模块和主驱动控制模块在内的主要电路的作用和设计方案,给出了系统组成框图、硬件设计部分的模块封装图以及仿真结果;本驱动控制电路成功实现了对DMD成像系统的驱动控制。
According to the display properties of Digital Micromirror Devices （DMD）, a DMD drive control system based on FPGA chip is introduced. Started from the work process of the micromirror and the theory of binary pulse width modulation （BPWM）, the principles and designing proposal of independent development of drive control system with limited use of the TI＇s chips is described. Including a detailed analysis of the image decoding module and the main drive control module, the system block diagram, hardware design, part of the module package diagram and the simulation results are given to prove the success in driving and controlling the system.
