void TIM14_init(void){ RCC->APBENR2|=(1<<15); TIM14->PSC= 31; TIM14->SR=0; TIM14->CNT=0; TIM14->EGR|=(1<<0); } void TIM14_delay_us (int delay_us){ TIM14->ARR = delay_us; TIM14->CR1|= (1<<0); // counter enabled while (!((TIM14->SR)&1)); // wai...

Erasing a page of flash on STM32L476RG

Hello everybody,I'm working on an STM32L476RG. For the moment, I'm using a nucleo-476RG board.I'm trying to write and read some data in the flash memory.I'm trying to write at the address : 0x080FF800 (first address of last page of the memory).I do t...

What is the maximum operating speed of GPIO output? (STM32F303RB)

Hello,I'm using STM32F303RB and 72MHz Clock is being used by using PLLI have a few questionsQ1) What is the maximum operating speed of GPIO output? (8MHz or 72Mhz) Q2) Is there PORT with bit banding?Thank for all your supoort. Best regrads. JH moon. 

Standby mode SDRAM sometime draw more power than usual.

If no SDRAM (disabled), enter standby mode always work as expected.When SDRAM enabled, sometime enter standby mode, draw 3mA more than usual.This is code to put SDRAM to self refresh mode before enter standby:````sdramState.command.CommandMode = FMC_...

Setup SAI - read adc values from AD7771 via DOUTx interface lines

Hi,I have STM32H743Z and ADC converter AD7771. I want to use SAI interface for reading data from it. I have configured AD7771, that results form conversions are sent over DOUT_0 line. In oscilloscope I can see line DRDY (falling edge), line DOUT0 sen...

malloc or calloc allocation on stm32. I store some strings with calloc allocation and display that strings on the api text box. strings seems to be showing static on the api text box.Outputing strings are dynamic to be display on api text box.

Its the same strings showing on api text box. It does not change. But when I debug it I can see it changing and display on api (application interface) text box. Any idea about this?

How can I create an Assembly Language Project within KEIL uV 5 with or without Cube MX?

Dear I appreciate if someone leads me to learn how to create an assembly program within KEIL uVision 5.I develop on STM32F030 series micro-controllers. Is it possible in older versions, i.e. uV 4, uV 3, ... etc?Best Regards!

Dear ST Team, Would you able to advise the product identification marking for STM32G061F8Y6TR? Is it just 3G06? Thanks.

STM32F303 HAL ISR being called twice

Hello!I am writing a program in which I am controlling a ST32F303 MCUs DAC1 and DAC2, thru a USB port, via LabView. The LabView part sends a data string containing the following "1,4095". The one implicates which DAC I am trying to control(in this ca...
