How can I measure encoder velocities using pulse width measurements (low RPM)?
Hi,I am using the STM32F303RBTx MCU and currently have a quadrature (4x) encoder set up on TIM2. You can find my STM32CubeMX configuration settings below: I would like to implement a tachometer for this encoder. I am aware of the method of periodical...
STM32G474 boots with FPU enabled when BFB2=1
We are using the STM32G474 MCU in dual-bank mode. In the options registers we have DBANK=1 and BFB2=0 or 1 depending on which bank we are booting from at the moment (we swap banks during firmware updates). We have found that when booting and BFB2=0 t...
Resolved! Working of RTO (receiver timeout) in UART?
Hello,I have been looking into this RTO flag provided in STM32F303 UART.According to the manual"The timeout function and interrupt must be activated, through the RTOEN bit in the USART_CR2 register and the RTOIE in the USART_CR1 register. The value c...
STM32F4 using DMA and ADC with LL
Hello, I'm working with a nucleo F401RE board and the LL drivers, I have set up the ADC in DMA mode, checking into the DMA register all seems right, but when I start the ADC it converts only one value and than it stop, the ADC is triggered from an EX...
Unreadable flash due to power failure
We met with strange problem with STM32H743. Could you please advice how to diagnose the following bug/effect of built-in flash :we use STM32H743 at our device. We calibrate the device within assembling procedure. The calibration data stored in built-...
STM32U5 GPDMA
Hi,The GPDMA of the STM32U5 is much more complex to configure than the DMA of the other STM32. I would like to know in which applications GPDMA is better than DMA and also would like to know if ST has plans to use GPDMA in future general purpose micr...

Resolved! STM32G473CB Flash Bank Configuration
I'm currently trying to implement the eeprom emulation library provided by ST on an STM32G473CB. However, I'm dubious about whether this library, and also the HAL flash modules, are properly detecting that I'm working with this specific device.From w...
