ROS spinOnce jamming the process of MCU

We are using ROS Serial to let Raspberry Pi and STM32F103C8T6 communicate with each other. And there is another UART channel for IMU to use. We observe that the spinOnce function of ROS jammed the process of MCU. Therefore, other work cannot operate ...

STM32H7 series resistors in data lines ?

With a 400MHz clock and very high speed ports, I was assuming the faster data lines would need series resistors to avoid reflections in the way things like FPGAs do. But I've just noticed the evaluation board doesn't have any and routes even high spe...
