Hello ST Community,I have a question regarding the compatibility of the STLINK-V3MODS SWD pins with my MCU's SWD pins, which operate at 3.3V. Do I need to use logic level shifters between them, or are the STLINK-V3MODS SWD data signals fully compatib...

Hi everyone,I'm working with the STM32F429i-Disc1 board, writing code from scratch, and I encountered something odd. I created an empty project for the LCD, and during the LTDC pin initialization, I mistakenly set the alternate function (AF) to the w...

Hi St community,I noticed that the SB9 bridge on the STM32F429I-DISC1, which connects the SWO pin of the ST-Link to PB3 on the STM32, is ideally not soldered by default.Is there any specific reason for this? Does it affect the SWO functionality or de...

Hello ST Community,I am working on a project using an STM32 microcontroller with USB CDC class for communication. I am using the CDC_Transmit_FS function to send data over USB, but I am looking for best practices to handle the completion of data tran...

Hello ST Community,I am currently working on a project using an STM32 microcontroller, where I have implemented a feature to transmit the current date and time over USB when a user button is pressed. The USB transmission is handled using the CDC cla...

Hi @waclawek.jan,Thanks for the explanation!I actually tried de-initializing these pins (PB0, PB1, PG10, and PG12) completely, but the LCD still works. It's strange, as I would expect the display to stop functioning if the pins weren't properly confi...

It seems you're not calling the FlashInit() function before HAL_FLASHEx_Erase_IT(&EraseInitStruct). Ensure to include FlashInit() to enable NVIC for FLASH Interruption before initiating the erase operation:

@AnanyaRavi29 Try this callback function it will work for you, (it correctly handles the overflow of seconds by wrapping around): void HAL_RTC_AlarmAEventCallback(RTC_HandleTypeDef *hrtc) { RTC_AlarmTypeDef sAlarm; HAL_RTC_GetAlarm(hrtc, &sAlarm,...

@AnanyaRavi29 Did you tried the exact code for toggling the LED for exactly 1 second, as provided in the "Getting started with RTC " guide on the STM32 MCU website. I think you may have missed some steps.

Make sure that the flash interrupt is enabled in your NVIC (Nested Vectored Interrupt Controller) settings. This typically involves calling the appropriate HAL function to enable the interrupt, such as HAL_NVIC_EnableIRQ(FLASH_IRQn).
