大家好,如果我在一个项目中的一个FPGA.vi里进行了电平设置,和I/O端口方向设置,那么我在其他FPGA.vi里还需要重新设置电平和方向吗?
我觉得不需要重新设置,因为同属一个项目,而且又没有断电。但我又觉得应该重新设置,因为在用到设置电平的FPGA.vi后,就要关闭此FPGA.vi引用,所以此设置用不到其他FPGA.vi里。
我问这个问题的原因是,考虑需不需要在host.vi里多次查看I/O status。比如查看功率是否可以,I/O模块是否有效,端口是否正常,电平是否设置完成等等。
谢谢大家!
已解决! 转到解答。

Hi 郭旭辉1999,
这个涉及到你程序的设计,所以不会有一个标准答案。基本上来讲,一旦一个FPGA程序被编译成bit file并部署到FPGA上,FPGA上的逻辑就会相应改变,这种改变会保持直到另一个bit file被部署。
谢谢,祝好。
