Hi,
I have configured MCU in Sleep Mode, I have Configured SPI,UART and Some GPIO. and also configured Interrupt RTC. I have Wrote entering Sleep mode like,
main()
{
MX_GPIO_Init();
MX_LPUART1_UART_Init();
MX_SPI1_Init();
while(1)
{
Disable_Pheripheral(void);
Enter_Sleep_Mode(void);
Enable_Pheripheral(void);
//After wakeup do somthing
}
}
void Disable_Pheripheral(void)
{
CLEAR_BIT(LPUART1->CR1,USART_CR1_RXNEIE);
HAL_UART_MspDeInit(&hlpuart1);
CLEAR_BIT(SPI1->CR1,SPI_CR1_SPE);
HAL_SPI_MspDeInit(&hspi1);
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_InitStructure.Pin = GPIO_PIN_2 |GPIO_PIN_3|GPIO_PIN_5 |GPIO_PIN_6 |GPIO_PIN_7;
GPIO_InitStructure.Mode = GPIO_MODE_ANALOG;
GPIO_InitStructure.Pull = GPIO_NOPULL;
HAL_GPIO_Init(GPIOA, &GPIO_InitStructure);
/* Disable GPIOA clock */
__HAL_RCC_GPIOA_CLK_DISABLE();
}
void Enter_Sleep_Mode(void)
{
__HAL_FLASH_SLEEP_POWERDOWN_ENABLE();
HAL_SuspendTick();
/* Enter Sleep Mode , wake up is done once Interrupt Generates */
HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);
/* Resume Tick interrupt if disabled prior to sleep mode entry */
HAL_ResumeTick();
__HAL_FLASH_SLEEP_POWERDOWN_DISABLE();
}
void Enable_Pheripheral(void)
{
/* Enable GPIOA clock */
__HAL_RCC_GPIOA_CLK_ENABLE();
HAL_SPI_MspInit(&hspi1);
SET_BIT(SPI1->CR1,SPI_CR1_SPE);
HAL_UART_MspInit(&hlpuart1);
SET_BIT(LPUART1->CR1,USART_CR1_RXNEIE);
}
This is right way to entering sleep mode?
