annotate Common/Drivers/STM32F4xx_HAL_Driver/Src/stm32f4xx_ll_usart.c @ 217:ce05c801b002 Improve_IPC_Sync

Moved display refresh and button action function from tim callback to main loop The update of the display, especially for log book pages, may take some time causing problem because the execution of other functions (like SPI) was shifted => SPI errors.
