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) |

|
|
| 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) |
