DM365 RTC GPIO Interrupt 我们在做的项目方案是DM365平台,在应用过程中,由于使用内部网卡,可用中断IO不多,所以使用了RTC GIO 当做外部中断过程中,发现RTC GIO 中断响应很慢,达到毫秒级。根本不可能应用。我的内核是linux 2.6.32 。不知道什么原因会导致上面的情况。现在我不能使用外部中断,没有多余的中断引脚,...

通过串口配置修改将RTC计数寄存器修改为当前时间,开启RTC秒中断(Second Interrupt),1S产生一次RTC中断,并通过串口助手实时显示时间。备份寄存器在这个例程中的作用就是检查RTC是否被配置了。由于使用的最小系统板VBAT引脚没有接电池,所以需要单独供电,断电后BKP的内容会被清空。 整体流程图# 通过串口修改RTC外设寄存器的值...
