我使用的是Virtual Serial Port Driver和丁丁串口助手,你也可以使用自己熟悉的软件,如果找不到或使用,安装这两个软件有问题可以私信。 虚拟串口驱动软件安装后配置两个成对的虚拟串口一个对应仿真电路中的串口接口,一个对应在串口助手软件上,这样就相当于将两个软件通过虚拟串口连接在一起了,将他们配置成相同的串口参...
RS232的电平使用负逻辑电平,和FPGA 的电平(TTL)不一样,需要中间的转换芯片,一般常用的有SP3232、ZT3232LEEY,将+-15v的逻辑电平转换为TTL电平(3.3v为高电平,0v为低电平)。 但DB9的体积比较大,为了节省开发板的空间,现在都用usb口替代,比如C5G和TSP开发板,分别用FT232R和CP2102N来作为USB电平和TTL电平之间的...
