c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	352 IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	353 on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	354 is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	355 While receiving data, transmission should be avoided as the data to be transmitted
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	356 could be corrupted.

c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	358 (#) There are two modes of transfer:

c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	360 The HAL status of all data processing is returned by the same function
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	361 after finishing transfer.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	362 (++) No-Blocking mode: The communication is performed using Interrupts

c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	364 The end of the data processing will be indicated through the
