flash的引脚问题,我用QUATUESII产生
read_n_to_the_cfi_flash
select_n_to_the_cfi_flash
write_n_to_the_cfi_flash
这三个引脚怎么分配???
我的flash芯片上的控制引脚有
WE
RESET
WP
RY
CE
OS
BYTE
但是没有CS引脚,不知道如何分配才合适,请高人指教.
还有我将程序烧进flash中时有错误!!

请问是不是引脚分配不当还是别的什么原因造成的????????????

一般的
“CS” = Chip Select
“CE” = Chip Enable
居多的芯片厂家爱用“CS”表示,也有的用“CE”,两者是同样的意思。
