Resolved! What does 'Value Line' stand for? What is the difference to the 'non Value Line' devices?
Several MCU are described with the label 'value line' but I could not find an explanation what that mean. I assume it is related to a system architecture, right?
HEX file in stm32F4
Hi folks.. I did a bootloader for the STM32F4 microcontroller.. I read a text file and I flash the bytes.. i really don't understand the following parts of the HEX file ,.. :020000040800F2 :040000050800ACB98A The other parts of the fix are addre...
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...
