From 43c473530552acabcf5bb1db29555bfb5ea70b79 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Sun, 30 Jan 2011 21:02:31 +0000 Subject: Renamed the PRNT_Host_SendString(), CDC_Host_SendString() and CDC_Device_SendString() functions to *_SendData(), and added new versions of the *_SendString() routines that expect a null terminated string instead. Added new Serial_SendData() function to the Serial driver. --- LUFA/Drivers/USB/Class/Host/CDC.c | 23 ++++++++++++++++++++--- LUFA/Drivers/USB/Class/Host/CDC.h | 32 ++++++++++++++++++++++++-------- LUFA/Drivers/USB/Class/Host/Printer.c | 27 +++++++++++++++++++++++++-- LUFA/Drivers/USB/Class/Host/Printer.h | 19 ++++++++++++++++--- 4 files changed, 85 insertions(+), 16 deletions(-) (limited to 'LUFA/Drivers/USB/Class/Host') diff --git a/LUFA/Drivers/USB/Class/Host/CDC.c b/LUFA/Drivers/USB/Class/Host/CDC.c index 27d4a102a1..73e634b99a 100644 --- a/LUFA/Drivers/USB/Class/Host/CDC.c +++ b/LUFA/Drivers/USB/Class/Host/CDC.c @@ -311,9 +311,26 @@ uint8_t CDC_Host_SendBreak(USB_ClassInfo_CDC_Host_t* const CDCInterfaceInfo, return USB_Host_SendControlRequest(NULL); } +uint8_t CDC_Host_SendData(USB_ClassInfo_CDC_Host_t* const CDCInterfaceInfo, + const uint8_t* const Buffer, + const uint16_t Length) +{ + if ((USB_HostState != HOST_STATE_Configured) || !(CDCInterfaceInfo->State.IsActive)) + return PIPE_READYWAIT_DeviceDisconnected; + + uint8_t ErrorCode; + + Pipe_SelectPipe(CDCInterfaceInfo->Config.DataOUTPipeNumber); + + Pipe_Unfreeze(); + ErrorCode = Pipe_Write_Stream_LE(Buffer, Length, NULL); + Pipe_Freeze(); + + return ErrorCode; +} + uint8_t CDC_Host_SendString(USB_ClassInfo_CDC_Host_t* const CDCInterfaceInfo, - const char* const Data, - const uint16_t Length) + const char* const String) { if ((USB_HostState != HOST_STATE_Configured) || !(CDCInterfaceInfo->State.IsActive)) return PIPE_READYWAIT_DeviceDisconnected; @@ -323,7 +340,7 @@ uint8_t CDC_Host_SendString(USB_ClassInfo_CDC_Host_t* const CDCInterfaceInfo, Pipe_SelectPipe(CDCInterfaceInfo->Config.DataOUTPipeNumber); Pipe_Unfreeze(); - ErrorCode = Pipe_Write_Stream_LE(Data, Length, NULL); + ErrorCode = Pipe_Write_Stream_LE(String, strlen(String), NULL); Pipe_Freeze(); return ErrorCode; diff --git a/LUFA/Drivers/USB/Class/Host/CDC.h b/LUFA/Drivers/USB/Class/Host/CDC.h index 3b84bb2d7c..5f59e0c3a3 100644 --- a/LUFA/Drivers/USB/Class/Host/CDC.h +++ b/LUFA/Drivers/USB/Class/Host/CDC.h @@ -197,23 +197,39 @@ uint8_t CDC_Host_SendBreak(USB_ClassInfo_CDC_Host_t* const CDCInterfaceInfo, const uint8_t Duration) ATTR_NON_NULL_PTR_ARG(1); - /** Sends a given string to the attached USB device, if connected.
