I use the UART on a STM32F7 with DMA. Is there any way to detect a stop of an incoming transmission with an interrupt e.g. with HAL_UART_ErrorCallback? If I expect too many characters or not all characters are transmitted?

I would like to use the DSP. Unfortunately it already fails because of the #include "arm_math.h".The file is not available in the project.Is there a suitable tutorial somewhere, everything I found so far does not work.I use a STM32F7 and STM32CubeIDE...

I use the STM32F7 and I want to change the baud rate of the USART6 from 115200 to 921600 during runtime, how can I do that?

I’m using STM32CubeIDE 1.2.1 and TouchGFX 4.13.0 with STM32F746G-DISC0 kit.I would like to calculate an image at runtime and then display it. Is there a manual or something similar? I have tried the AnimationStorage, unfortunately getAnimationStorage...
