Functions

Ecode_t UARTDRV_Abort (UARTDRV_Handle_t handle, UARTDRV_AbortType_t type)
 Abort ongoing UART transfers. More...
 
Ecode_t UARTDRV_DeInit (UARTDRV_Handle_t handle)
 Deinitialize a UART driver instance. More...
 
UARTDRV_FlowControlState_t UARTDRV_FlowControlGetPeerStatus (UARTDRV_Handle_t handle)
 Checks the peer's flow control status. More...
 
UARTDRV_FlowControlState_t UARTDRV_FlowControlGetSelfStatus (UARTDRV_Handle_t handle)
 Checks the self's flow control status. More...
 
Ecode_t UARTDRV_FlowControlIgnoreRestrain (UARTDRV_Handle_t handle)
 Enables transmission when restrained by flow control. More...
 
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. More...
 
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. More...
 
UARTDRV_Count_t UARTDRV_ForceReceive (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t maxCount)
 Direct receive without interrupts or callback. Blocking function. More...
 
Ecode_t UARTDRV_ForceTransmit (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
 Direct transmit without interrupts or callback. Blocking function that ignores flow control if enabled. More...
 
UARTDRV_Status_t UARTDRV_GetPeripheralStatus (UARTDRV_Handle_t handle)
 Returns the status of the UART peripheral associated with a given handle. More...
 
uint8_t UARTDRV_GetReceiveDepth (UARTDRV_Handle_t handle)
 Returns the number of queued receive operations. More...
 
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. More...
 
uint8_t UARTDRV_GetTransmitDepth (UARTDRV_Handle_t handle)

 Start a non-blocking receive. More...
 
Ecode_t UARTDRV_ReceiveB (UARTDRV_Handle_t handle, uint8_t *data, UARTDRV_Count_t count)
 Start a blocking receive. More...
 
Ecode_t UARTDRV_ResumeTransmit (UARTDRV_Handle_t handle)
