Option Byte Programming Fail -> HAL_FLASH_OB_Launch() returns HAL Error
I am trying to flash options bytes on a STM32H7 via the code below. Both the code snippets return HAL_ERROR from the HAL_FLASH_OB_Launch(). What am I doing wrong?I am referring to the following STM32Cube example code: https://github.com/STMicroelectr...
Is the temperature sensor factory calibrated?
We are currently using an F4 (STM32F407IGH6) and an F3 (STM32F303VC) in our product. We want to pull the temperature sensors to get an idea of chip temp. Looking at the datasheets, the F3 data sheet explicitly states that factory calibraiton is done...
Resolved! ADC with DMA in discontinuous mode samples first rank twice (STM32F103)
Hi,I want to use an ADC with DMA in a STM32F103. I configured it in Cube as you can see in the following picures.When I start the conversion with HAL_ADC_Start_DMA(&hadc1,(uint32_t*)AdcData,5);HAL_ADC_ConvCpltCallback() is called and I see that the A...
Hi all: Where can i found the documents have the information of "Error data and analysis of STM32 chip", and the "Die revision" of MCU?? I' m use the STM32F303xE chip. Thanks.
We need that do do the UL certifications..anyone could help?thanks.
MCU working issue.
I am using STM32F439ZGT6.I have flashed the code to this controller. After flashing the code when I restart (power off and power on ) the MCU first time, that time unit is working absolute fine but if I power off and power on the unit, that time I am...
CubeMX SystemClock_Config is resetting my RTC due to LL_RCC_ForceBackupDomainReset
STM32CubeMX 5.6.1 , Atollic TrueStudio 9.3.0 , MCU is a STM32L053 with VDD wired to a coin cell. LSE is connected to a watch crystal.The RTC works fine. Going into standby mode works fine. Waking up from standby mode works fine. Checking and resettin...
Resolved! Behaviour of STM32H743 general purpose timer
Hello,I'm using TIM2 on STM32H743 (Nucleo, rev Y, Keil 5.31).Just before setting the bit TIM_CR1_EN the setting of the timer is the following:DIER : bit UIE setPSC: expected value (0x4E1F)ARR expected value (0x4E20). it is almost the same as PSC but ...
Resolved! STM32F030C6 wih external oscillator (HSE)
I am trying to understand how to setup the microcontroller (STM32F030 in this case) to use external oscillator. I am using blinking LED as a test to see if the code is running. To setup the HSE I did following:selected Crystal/Ceramic Resonator in Hi...
Resolved! STM32H743 IWDG continuously reset MCU
Strange behavior of STM32H743. It continuously reset every few seconds.I check reset reason with this part of code after system startup:if (__HAL_RCC_GET_FLAG(RCC_FLAG_IWDG1RST)) { _PRINTF("RESET_CAUSE_INDEPENDENT_WATCHDOG_RESET\n"); } else...
