Posted on January 30, 2018 at 13:05Dear sirs, i'm not able to go out from standby on my STM32F103C8T6 device.
Basically my test firmware is a simple blink.
After 5 blink i execute the instructions to go in standby.
Device goes in standby (current consumption goes low).
Problem is that i can't go out of standby with wake up pin.
Wake up pin (PA0) is configured properly but device is not able to go out from standby.
Here my semplified code to enter in standby:
//enter in Standby mode...
EWUP_bit = 1; //enable WKUP pin on rising edge...
SLEEPDEEP_bit=1; //Set SLEEPDEEP in Cortex-M3 System Control register
PDDS_bit = 1; //Set PDDS bit in Power Control register (PWR_CR)
CWUF_bit = 1;
//1 means clear the WUF Wakeup Flag.
asm WFE; //WFE (Wait for Event) execution
seems to be that rising edge of PA0 (0V to 3V3) is complitely ignored,
but i expect that led MCU start again from reset vector and led restart to blink.
Someone can suggest me something? Thanks and regards.
