3 years ago And this is my code that works to wake-up with interrupt to pin PA1 Rising. The code turn on a LED on PA4 for 5 seconds then goes to sleep and wake-up when press the button, then turn on the led again 5 seconds and repeat.
` /**
- Set MCU to STOPMode and wakeup from interrupt in PA1
- in this setting my board uses 10 uA */
include "Arduino.h"
define LED_Pin PA4
define KEY_Pin PA1
void LED_Toogle(){
pinMode(LED_Pin, OUTPUT);
togglePin(LED_Pin);
//Restart the clock after awake InternalClocks_Init(); }
void enterStopMode(){ //I dont know what the below line does but decrease the power by 10uA RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE); //Turn on the power management clock
//Set the Regulator in Low Power and can be awake by an interrupt PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI); }
/*
-
Set Pins to Analog to decrease power usage */ void setPinsToAnalog(){ pinMode(PA0, INPUT_ANALOG); //pinMode(PA1, INPUT_ANALOG); //If set to analog Interrupt do not work pinMode(PA2, INPUT_ANALOG); pinMode(PA3, INPUT_ANALOG); pinMode(PA4, INPUT_ANALOG); pinMode(PA5, INPUT_ANALOG); pinMode(PA6, INPUT_ANALOG); pinMode(PA7, INPUT_ANALOG);
pinMode(PA9, INPUT_ANALOG); pinMode(PA10, INPUT_ANALOG);
pinMode(PB1, INPUT_ANALOG);
pinMode(PF0, INPUT_ANALOG); pinMode(PF1, INPUT_ANALOG); }
void setup(){ pinMode(LED_Pin, OUTPUT); pinMode(KEY_Pin, INPUT_PULLDOWN); attachInterrupt(KEY_Pin, LED_Toogle, RISING); }
void loop(){ //Just Keep the LED On to measure the running power digitalWrite(LED_Pin, HIGH); delay(5000); digitalWrite(LED_Pin, LOW);

Hello.
I have been for a while diving in information and looking in the internet before coming to ask.
I am testing out the Low Power Modes in the STM32F03F4P6, at this point I have been able to use the STOPMode and wake-up with a pin Interrupt, in my custom PCB the power goes low to 10uA, really good.
But I want to know how to make it awake every certain amount of time then sleep again, for example to read a sensor, send the data then sleep some minutes and do it again.
I have been trying using the Timer example, not success there. Probably I am missing something important. I read something about this line of code NVIC_SystemLPConfig(NVIC_LP_SLEEPONEXIT, ENABLE); but I really cannot understand the process to follow, if someone can point me in the right direction it will be great.
This is the code I have been trying unsuccessfully.
` #include "Arduino.h"
define LED_Pin PA4
define KEY_Pin PA1
void Timer1_Callback(){ pinMode(LED_Pin, OUTPUT); togglePin(LED_Pin); TIM_Cmd(TIM1, DISABLE); InternalClocks_Init(); //Setup the clock after awake }
void enterStopMode(){ Timer_SetInterrupt(TIM1, 1000000/@1s/, Timer1_Callback); TIM_Cmd(TIM1, ENABLE);
//I dont know what the below line does but decrease the power by 10uA RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE); //Turn on the power management clock
//Set the Regulator in Low Power and can be awake by an interrupt PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI); }
//Set Pins to Analog to decrease power usage void setPinsToAnalog(){ pinMode(PA0, INPUT_ANALOG); pinMode(PA1, INPUT_ANALOG); //If set to analog Interrupt do not work pinMode(PA2, INPUT_ANALOG); pinMode(PA3, INPUT_ANALOG); pinMode(PA4, INPUT_ANALOG); pinMode(PA5, INPUT_ANALOG); pinMode(PA6, INPUT_ANALOG); pinMode(PA7, INPUT_ANALOG); pinMode(PA9, INPUT_ANALOG); pinMode(PA10, INPUT_ANALOG); pinMode(PB1, INPUT_ANALOG); pinMode(PF0, INPUT_ANALOG); pinMode(PF1, INPUT_ANALOG); }
void setup(){ pinMode(LED_Pin, OUTPUT); pinMode(KEY_Pin, INPUT_PULLDOWN);
// it is supposed to allow to wakeup with the time but it did not work. NVIC_SystemLPConfig(NVIC_LP_SEVONPEND, ENABLE); }
void loop(){ //Just Keep the LED On to measure the running power digitalWrite(LED_Pin, HIGH); delay(5000); digitalWrite(LED_Pin, LOW);
//Go to Sleep setPinsToAnalog(); enterStopMode(); }
/**
int main(void) { InternalClocks_Init(); //Set the internal clock @ 8MHz Delay_Init(); setup(); for(;;)loop(); } `
