Hi,I'm using STM32CubeMx to generate UART initialisation code for STM32H743 controller. I'm able to test UART communication for baud rate 3686400. I'm not able to make UART communication up & running when I changed baud rate to 4000000.Is there other...
Hello,My question is that how many interrupts could be in pending state in STM32F1 MCUs? What would happen when a interrupt is running and in the same time another interrupt with same preempt priority be fired, does the running interrupt finishes and...
I am currently using an STM32L475VCT in my board design, and I also have an STM32L476G-EVAL board.I have ADC1 set up for sampling 6 channels continuously. Each conversion is triggered by an output from timer 1, I am also using 4x oversampling. The ti...
Dear all,In my system, STM32L412 is between MCU_B and Dev_S. The role of the STM32L412 is a bit like I2C bridge.That means MCU_B does any I2C read/write command from/to Dev_S must by the help of STM32L412.It is simple for STM32L412 receives I2C write...
Why would an ADC sample in 8-bit mode when DMA is used, but when used without DMA the full 12-bit conversion is retrieved?STM32F411 I am trying to set up an example project for ADC with DMA using HAL library.I am sampling a slow ramp function from 0-...
I tried to test the main while loop frequency with short code that throw the HAL_GetTick() through uart (baudrate of 115200) and present it every 18000000 (18M) main while loops, I also measured the time between each loop and I got the same value of...

I was able to get this working for the L5 with one large circular buffer and interleaved values from the ADC channels 1-4.Given the improved DMA on the U5, I expect that the DMA will not have to generate an interleaved circular buffer of ADC channel ...
Hello.I'm finding the MTBF data of MCU STM32H7B3IIK6Q working at 60℃. The document UM2331: STM32H7 single-core safety manual not answer my question, as it is a general introduction about the reliability of STM32, but not include the detailed MTBF or ...
In the STM32f302R8 Reference manual, it is stated for master initialization, I need to Enable Interrupts and/or DMA in I2C_CR1:Does this mean I need to enable all the bits that is related to interrupts? Example, from bit 1 until bit 8, do I need to e...
