内部资料，CCD探头采集时序发生器，基于CPLD用VHDL编写，是学习CPLD和VHDL在实际工业应用中的实际案例。-Internal information, medical collection probe CCD Timing Generator, based on the CPLD using VHDL, CPLD and VHDL to learn practical industrial applications in the real case.

Its only a schematic of probe to complete the sending of data through rs232

基于fpga和传统示波器工作方式的vhdl程序，通过ad0809采样信号（可兼容tlc5510）再经由8位da转换输出，同时输出外触发锯齿波，建议使用感性小的示波器探头，否则锯齿波低频时会出现失真-Fpga-based and traditional ways of working oscilloscope vhdl procedures, through ad0809 sampling signal (compatible tlc5510) and then through eight da
