Hello ,I have used the below to go into stop mode: HAL_PWR_EnterSTOPMode( PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI ); /* CPU will be halted here until a wakeup event occurs */ in the above function, what is the difference PWR_SLEEPENTRY_WFI & P...

I am working on STM32L051R8, which is set to use Stop mode, which wakes up on the start bit. I have a situation where the MCU wakes up on an unwanted start bit, and UART extracts unwanted data. The expected action is to ignore the unwanted data and e...

Hello , i am looking to know for STM32L051 how long will it take a byte to be written in to eeprom.while writing eeprom does it have any limitations like UART intteruptions?

hi all, I am using STLINK/V2 ISOL which says ST_LINK, No MCU device found, just replacing with STLINK/V2 works keep all setup intact.what could be the reason.

PWR_SLEEPENTRY_WFI was used HAL_PWR_EnterSTOPMode() , what are the effects when used?

It is ignored ./ got PE but the designed /architecture makes next frame missed .as mentioned the goal CLEAR_BIT( huart1.Instance->CR1, USART_CR1_RE ); works when it is not needed.but by using CLEAR_BIT( huart1.Instance->CR1, USART_CR1_RE ); the curr...

while keeping the UART_RX high, can we enable stop mode? if so how do we do that in FW?

The red arrow is where the MCU should wake up on the start bit from stop mode. The red block is where the Rx should ignore the received data, but the yellow arrow is the data received, which is not expected.

yes, it is ignored but the data of the wanted was partially taken too which causing problem , so the logic i have device wakes up early than expected then ignore the data by the above code and listen to start bit again .
