USART_TransferSendNonBlocking not exists in SDK for LPC55S16

Hi Community,

i have the following Problem:

SDK says following:

status_t USART_TransferSendNonBlocking(........)

Note The kStatus_USART_TxIdle is passed to the upper layer when all data is written to the TX register. However it does not ensure that all data are sent out. Before disabling the TX, check the kUSART_TransmissionCompleteFlag to ensure that the TX is finished.

But i can not find the definition of kUSART_TransmissionCompleteFlag....

Best Ralf

Hi Ralf

The comment related with kUSART_TransmissionCompleteFlag is no use. Please ignore it.

We will remove this unused comment in next SDK release (SDK 2.11.0 Major )

Thank you for bringing the problem to our attention.

Have a nice day,

Jun Zhang
