Functions

Ecode_t UARTDRV_Abort (UARTDRV_Handle_t handle, UARTDRV_AbortType_t type)
 Abort ongoing UART transfers.
 
Ecode_t UARTDRV_DeInit (UARTDRV_Handle_t handle)
 Deinitialize a UART driver instance.
 
UARTDRV_FlowControlState_t UARTDRV_FlowControlGetPeerStatus (UARTDRV_Handle_t handle)
 Check the peer's flow control status.
 
UARTDRV_FlowControlState_t UARTDRV_FlowControlGetSelfStatus (UARTDRV_Handle_t handle)
 Check the self flow control status.
 
Ecode_t UARTDRV_FlowControlIgnoreRestrain (UARTDRV_Handle_t handle)
 Enable transmission when restrained by flow control.
 
Ecode_t UARTDRV_FlowControlSet (UARTDRV_Handle_t handle, UARTDRV_FlowControlState_t state)
 Set UART flow control state. Set nRTS pin if hardware flow control is enabled. Send XON/XOFF if software flow control is enabled.
 
Ecode_t UARTDRV_FlowControlSetPeerStatus (UARTDRV_Handle_t handle, UARTDRV_FlowControlState_t state)
 Set peer UART flow control state. Pause/resume transmit accordingly. Only for manual software flow control.
 
UARTDRV_Count_t UARTDRV_ForceReceive (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t maxCount)
 Direct receive without interrupts or callback. This is a blocking function.
 
Ecode_t UARTDRV_ForceTransmit (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
 Direct transmit without interrupts or callback. This is a blocking function. that ignores flow control if enabled.
 
UARTDRV_Status_t UARTDRV_GetPeripheralStatus (UARTDRV_Handle_t handle)
 Return the status of the UART peripheral associated with a given handle.
 
uint8_t UARTDRV_GetReceiveDepth (UARTDRV_Handle_t handle)
 Return the number of queued receive operations.
 
UARTDRV_Status_t UARTDRV_GetReceiveStatus (UARTDRV_Handle_t handle, uint8_t **buffer, UARTDRV_Count_t *itemsReceived, UARTDRV_Count_t *itemsRemaining)
 Check the status of the UART and gather information about any ongoing receive operations.
 
uint8_t UARTDRV_GetTransmitDepth (UARTDRV_Handle_t handle)
 Returns the number of queued transmit operations.
 
UARTDRV_Status_t UARTDRV_GetTransmitStatus (UARTDRV_Handle_t handle, uint8_t **buffer, UARTDRV_Count_t *itemsSent, UARTDRV_Count_t *itemsRemaining)
 Check the status of the UART and gather information about any ongoing transmit operations.
 
Ecode_t UARTDRV_InitLeuart (UARTDRV_Handle_t handle, const UARTDRV_InitLeuart_t *initData)
 Initialize a LEUART driver instance.
 
Ecode_t UARTDRV_InitUart (UARTDRV_Handle_t handle, const UARTDRV_InitUart_t *initData)
 Initialize a U(S)ART driver instance.
 
Ecode_t UARTDRV_PauseTransmit (UARTDRV_Handle_t handle)
 Pause an ongoing transmit operation.
 
Ecode_t UARTDRV_Receive (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count, UARTDRV_Callback_t callback)
 Start a non-blocking receive.
 
Ecode_t UARTDRV_ReceiveB (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
 Start a blocking receive.
 
Ecode_t UARTDRV_ResumeTransmit (UARTDRV_Handle_t handle)
 Resume a paused transmit operation.
 
Ecode_t UARTDRV_Transmit (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count, UARTDRV_Callback_t callback)
 Start a non-blocking transmit.
 
Ecode_t UARTDRV_TransmitB (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
 Start a blocking transmit.
