基于VGA接口的视觉辅助驾驶系统投影信号转换电路设计

Design of Projection Signal Conversion Circuit of Visual Assisted Driving System based on VGA Interface

采用单片机AT89C51驱动TFT-LCD控制模块中的VGA接口,产生标准的显示信号并进行投影,设计VGA接口信号转换到模拟液晶屏上显示的驱动电路,利用AD9883A芯片强大功能,实现HUD信息显示。

The article uses the single-chip AT89C51 to drive the VGA interface in the TFT-LCD control module,generate standard display signals and project them,design the drive circuit that converts the VGA interface signals to the analog LCD screen,and use the powerful functions of the AD9883A chip to realize HUD information display.
