STM32L476RG with ADXL345 axis return 511

Hi everyone, I am beginner for STM32 and C. I am trying to use ADXL345 with STM32L476RG board. I watched video and I am trying to use same code but my y axis returns 511. When I move the adxl345, x and z values go to 511 and then go to 0 and 1. Here ...

stm32h745 M4 Core doesn't work properly

Hello All, I have a STM32H745-DISCO board and trying to run a very simple program where M7 toggles Green LED and M4 toggles RED Led. After programming, I can see that Green LED is toggling fine but RED LED is not.Below is my simple main code: M7: int...

Is UART_CR1.TE toggle sufficient for IDLE frame generation, if UART kernel clock is APB?

I experimented with this, however, as long as UART kernel clock was set to APB, idle frame was generated, even if the two instructions writing to UART_CR1 were immediately after each other. I may have overlooked something of course.I have no problem ...
