  • Fix HAL_TIM_IC_Stop_DMA() to stop DMA prior to disabling the channel
• HAL UART driver
  • Add new reception services APIs, allowing user to handle reception of unknown/variable lengths and to get notified about received data upon events at reception buffer filling or IDLE event on Rx line:
    • HAL_UARTEx_ReceiveToIdle(): allow user to receive data until a given number of data are received or until IDLE event occurs on Rx Line. In case of IDLE event detected during reception, function returns HAL_OK and provides number of received data (available data stored in reception buffer)
    • HAL_UARTEx_ReceiveToIdle_IT(): allow user to receive data in interrupt mode until a given number of data are received or until IDLE event occurs on Rx Line. When any of these 2 events occurs, a user callback HAL_UARTEx_RxEventCallback() is executed and reception is stopped. Callback provides number of received data (available data stored in reception buffer)
    • HAL_UARTEx_ReceiveToIdle_DMA(): allow user to receive data in DMA mode until DMA buffer filling Half Transfer and Transfer Complete events occur or until IDLE event occurs on Rx Line. When any of these 3 events occurs, a user callback HAL_UARTEx_RxEventCallback() is executed and provides number of received data (available data stored in reception buffer). In DMA Normal mode, reception ends after either DMA Transfer Complete or IDLE event occurs. In DMA Circular mode, reception goes on after all occurrences of HAL_UARTEx_RxEventCallback() calls.
    • User version of HAL_UARTEx_RxEventCallback() is to be implemented in user code (weak empty function defined in HAL code).
  • Rework BRR register value computation in HAL_UART_Init() for ROM size gain

  • Remove non-applicable LL_DBGMCU_EnableDBGSleepMode() and LL_DBGMCU_DisableDBGSleepMode() APIs
• LL TIM driver
  • Fix inverted LL_TIM_COUNTERMODE_CENTER_UP and LL_TIM_COUNTERMODE_CENTER_DOWN definitions

  • Change default CFGR1 register values in LL_UCPD_StructInit()
