Posted on May 17, 2011 at 12:20It can only be woken up by a rising edge on PA.0 (WKUP pin), but mine does not wake up.
Currently do it like this:
...
// Peripheral Clock - This is done in the init function, but I did it again here
RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR,ENABLE);
// Enable WKUP pin
PWR_WakeUpPinCmd(ENABLE);
// Insert a delay - I have also tried without this delay
Delay(0xFFFF); // for(; nCount != 0; nCount--);
// Request to enter STANDBY mode and wake up with rising edge of WKUP pin
PWR_EnterSTANDBYMode();
while(1)
{
// Infinite loop - It's OK because the system will reset anyways
}
The unit does not wake up (reset). I've tried with both the JTAG connected and not connected.
Port PA.0 (WKUP pin) has a pull-down resistor, leading to a momentary switch, with Vcc on the other side of the switch, which should be enought to generate the required rising edge when the button is pressed.
Any ideas?
Hello,
i would like to know if to wake up the SMT32 from Standby mode, I can configure by software any other pin, apart from Reset, Tamper and WKUP pins (I/O pins are high impedance). I am using a membrane keyboard, that's why I need 2 pins.
I have found something on RM0008 (6.2.3. Wakeup event management), but I'm not sure.
Thank you.
