Posted on August 02, 2012 at 17:12Hello, I'm hoping someone can either confirm or deny what I as seeing.
I've modified the PWR STANDBY example to check the working of all three WKUP pins.
I seem to have a problem when I enable WKUP2.
If I only enable WKUP1 & WKUP3 then both work as expected, but when I enable all three then none them work.
All I have done is to add in the additional calls to PWR_WakeupPinCmd as below:
PWR_WakeUpPinCmd(PWR_WakeUpPin_1, ENABLE);
PWR_WakeUpPinCmd(PWR_WakeUpPin_3, ENABLE);
PWR_WakeUpPinCmd(PWR_WakeUpPin_2, ENABLE);
If I comment out the third call that enabled WKUP2 then WKUP1 & 3 work again.
Even if the PC13 line was being pulled high or low by the eval board I would not expect it to prevent the other two from working.
Can anyone shed any light on this.
Thanks.
