stm32 standby mode-EEWORLD

Collect

Low Power Mode

Reduce the system clock speed.
When APBx and AHB peripherals are not used, turn off the corresponding peripheral clocks.
Sleep mode (Cortex™-M3 core is stopped, all peripherals including the peripherals of the Cortex-M3 core, such as NVIC, system clock (SysTick), etc. are still running)
Stop mode (all clocks are stopped)
Standby mode (1.8V core power is turned off)

Standby Mode Configuration Steps

1. Enable the power clock
2. Set the WKUP pin as the wake-up source
3. Enter standby mode

Example

void WKUP_init()
{
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE); //Enable power clock

    PWR_WakeUpPinCmd(ENABLE); //Set WKUP pin as wakeup source

    PWR_EnterSTANDBYMode(); //Enter standby mode}12345678

When entering standby mode, the emulator cannot download the program again. You can use USB to download the update

STM32 Series Chapter 12 - Principle of Capacitive Touch Button

principle: R: External capacitor charging and discharging resistor. Cs: Stray capacitance between TPAD and PCB. Cx: Capacitance between finger and TPAD when finger is pressed. Switch: Capacitor discharge switch, replaced by STM32 IO port. When not pressed, the charging time is T1 (default). When TPAD is pressed,

stm32 microcontroller detects 12V circuit

1. First, use the sampling circuit to divide the voltage to get a 3.3V voltage 2. Then use a voltage follower to convert the 3.3V high impedance signal voltage into a 3.3V low impedance drive voltage, which can be directly connected to the ADC pin of stm32 3. Note: The supply voltage of the op amp chip LM358 must be a

STM32 external interrupt study notes

Interrupt Classification The STM32's EXTI controller supports 19 external interrupt/event requests. Each interrupt has a status bit, and each interrupt/event has independent trigger and mask settings. The 19 external interrupts of the STM32 correspond to 19 interrupt lines, EXTI_Line0-EXTI_Line18: Line 0~15:

EXTI key interrupt: EXTI interrupt: Note: 1. EXTI interrupt is an external interrupt, and related interrupt management devices need to be configured. 2. If it is an event interrupt, there is no need to configure and manage this register. 3. Pay special attention to this relationship: the relationship b

STM32 PWM input mode

This program uses the PWM input mode, which is a special case of the input capture mode. Except for the following differences, the program works the same as the input capture mode. Two ICx signals are mapped to the same TIxl input (here CH1 and CH2). Both ICx signals are edge-active but have opposite polarities.
