Please unify SAIx_MCK/MCLK in datasheets
Please use the same form (probably SAIx_MCLK) for all instances.Of course this occurs on several places in that datasheet, and I've seen it in other STM32 datasheets, too.JW
issue PWM output with STM32F215 microcontroller.
I have noted in my program following behaviour.Fist time microcontroller is programmed with entire FLASH erased before, Program runs right.If I disconnect device or it is reprogrammed, PWM does not work.PWM will work again if previously, all FLASH is...
Resolved! Reset line pulled low for no reason
I have created my own board based on the STM32L073RZ where I copied certain bits from the NUCLEO borad. I am having a problem where I can't connect to it using the STLINK. I have found out that even with only power plugged in the reset line is pulled...
Resolved! Why can't I change any value in the FLASH_OPTR register?
I am using the STM32L431 MCU and I want to stop the IWDG when it enters the standby mode, so I want to try changing the value of the IWDG_STDBY bit to freeze the IWDG. I tried with any of the the following instuctions but nothing works.CLEAR_BIT(FLAS...

STM32L010F4 errata sheet
Hi,where can I find errata sheet for STM32L010F4? I cant believe that it has no error...Thanks.
STM32F7xx is a 216 MHz ARM MCU But I Can Not Generate Even 0.5 microsecond Timer Interrupt?
Hi,//In my project i want to use 0.5 us (500 nanosecond) timer interrupt counter. //The MCUs max speed is 216 MHz. To get 200 MHz clock frequency, My OSC and CLOCK Settings are void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct; RCC...
does anybody know whay the clock is 961 KHz not 2 Mhz
I do have the clock setup 60 Mhz (max is 80) for STM32FL41KBU6 and I ma dividing it by 30I need 60 because I am trying to setup ADC 1Msps. I shoud have 2 MHz on PIN PA8static void MX_TIM1_Init(void){ /* USER CODE BEGIN TIM1_Init 0 */ /* USER CODE EN...
How to get TEMPSENSOR voltage with ADC3 ?
void ADC3_config(void){ AdcHandle.Instance = ADC3; if (HAL_ADC_DeInit(&AdcHandle) != HAL_OK) { /* ADC de-initialization Error */ //Error_Handler(); } AdcHandle.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4; /* Synchronous clock mode,...
