Questions about 'PWR - Monitoring low-power modes' on page 300 of RM0433.
Could anyone tell me why the same "CPU power state: CPU in Run mode" and "Domainx power state: DRun mode" have two different GPIO states which are on the page 300 of RM0433?

UART at slow rates: How stupid just I am
I've just been caught by this very same issue:https://community.st.com/s/question/0D50X00009XkaBXSAZ/rm0090-usart-minimum-attainable-baudrateAt this place I'd like to ask ST to reconsider baudrates generation for both UART and SPI - please connect th...
How can I interface stm32f469i to an e4000h QR code scanner?
I know that I will need to use UART. but I don't know how to see the data sent and received and on what terminal will I be able to see all this.
C++ compiler options.
Hi.I thought this question is more suited to education.I have been working on a STM32F091 C++ project just to get an idea code size, and I noticed that the size of the binary is huge even when optimisation is set to (-Os). I think its because the co...
SPI 3-wire bidirectional master not sending clocks
I have an issue with SPI in bidirectional mode (MOSI, CLK and CS). I have a device which I need to write to and from. When I have to write to an adress in the slave device, it works perfectly: reg=0x04; CS_DRIVER_LOW c=HAL_SPI_Transmit_DMA(&hspi2,...

stm32f4 TIM2 multiple channel input capture
Hello,I'm trying to write a PWM input capture function(I only need the on time. not the frq and duty cycle) and I see that it takes two channels of a timer. I need to use all four channels, Is it possible?Thanks
Unable to output floats using printf() after migrating to latest STM32 FW version.
From my functioning STM32 (H7) project, I open the .IOC file which spawns STM32CubeMX, which generates a dialog asking:"This project was setup using STM32Cube firmware FW_H7 V1.9.0. The new STM32Cube V6.3.0 works best with STM32Cube firmware version...
Resolved! I want to know how to clear bank1 securable area in NUCLEO-STM32G431RB.
I have configed the FLASH_CR，SET_BIT(FLASH->CR, 1<<27);I want to know how to clear bank1 securable area.
