Absolute max rating for ADC pins on STM32G071 device family

We are using STM32G071 device family in our projects and need information on absolute maximum ratings for voltage on ADC pins.Datasheet states different values for different pins.Can you please confirm what are the abs max values for ADC pins on STM...

What is the difference between STM32L151CBU6 and STM32L151CBU6A? Can they be interchangeably used?

STM32H743ZIT6,What is the maximum turnover frequency about GPIO with Timer?

I want to output 5MHz PWM as other chip CLK signal.How to do it?

STM32H743zit6 After the timing interrupt is enabled, the interrupt callback function is executed repeatedly, and other programs cannot be executed?

CUBEMX Settings as above:The callback function is as follows：void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)   {   if(htim->Instance == TIM2)   {   LL_GPIO_TogglePin(CLK_GPIO_Port,CLK_Pin);   }   }The call code is as follows:USB_pri...

STM32H5 Comparator with EXTI_RPR1 and EXTI_FPR1 issue.

I get a STM32H5 Nucleo board (MB1814) and configured comparator with neccessary settings using CubeIDE and LL library and got next generated piece of code.I trigger mode choice Rising/Falling Edge Interrupt. LL_EXTI_EnableFallingTrig_0_31(LL_EXTI_LI...

STM32WB55 : EE_WriteVariable8bits returns EEPROM_WRITE_ERROR and FLASH_FLAG_BSY is set in FLASH->SR

I wonder if it is possible to use the DAC in STM32G4 to produce a 30kHz sinewave with 1Hz resolution.

The application is to fine tune acoustic resonantors. In other words we want to be able to tune DMA DAC output from 29.990 to 30.010 in 1 Hz steps. Ideally we also would like to tune the amplitude. There are some ideas with DAC reference prescalers a...

Atoi() and HAL_UART

Hello, My question is about language C.My nucleo receive some AT Command (from my pc) and i have write a function for compute the command.Ex : AT+SPEED? > return "SPEED" (only).>I 'm able to get only the command (by print over uart).>My command is st...
