From 5ce8380a7d076b5368d9800ff1aab89ba0487276 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Tue, 2 Nov 2010 11:16:36 +0000 Subject: Fix XPLAINBridge code broken during the changes to the Rescue Clock generation in the AVRISP-MKII clone project. Change over all low level host mode project's descriptor comparator routines to perform the descriptor casting in a temp variable to make the code clearer and easier to modify (despite being more verbose). --- Demos/Host/LowLevel/MIDIHost/ConfigDescriptor.c | 23 ++++++++++++++--------- 1 file changed, 14 insertions(+), 9 deletions(-) (limited to 'Demos/Host/LowLevel/MIDIHost') diff --git a/Demos/Host/LowLevel/MIDIHost/ConfigDescriptor.c b/Demos/Host/LowLevel/MIDIHost/ConfigDescriptor.c index cf1d4e69a..544e31ac8 100644 --- a/Demos/Host/LowLevel/MIDIHost/ConfigDescriptor.c +++ b/Demos/Host/LowLevel/MIDIHost/ConfigDescriptor.c @@ -126,12 +126,16 @@ uint8_t ProcessConfigurationDescriptor(void) */ uint8_t DComp_NextMIDIStreamingInterface(void* CurrentDescriptor) { - if (DESCRIPTOR_TYPE(CurrentDescriptor) == DTYPE_Interface) + USB_Descriptor_Header_t* Header = DESCRIPTOR_PCAST(CurrentDescriptor, USB_Descriptor_Header_t); + + if (Header->Type == DTYPE_Interface) { + USB_Descriptor_Interface_t* Interface = DESCRIPTOR_PCAST(CurrentDescriptor, USB_Descriptor_Interface_t); + /* Check the MIDI descriptor class, subclass and protocol, break out if correct data interface found */ - if ((DESCRIPTOR_CAST(CurrentDescriptor, USB_Descriptor_Interface_t).Class == AUDIO_CSCP_AudioClass) && - (DESCRIPTOR_CAST(CurrentDescriptor, USB_Descriptor_Interface_t).SubClass == AUDIO_CSCP_MIDIStreamingSubclass) && - (DESCRIPTOR_CAST(CurrentDescriptor, USB_Descriptor_Interface_t).Protocol == AUDIO_CSCP_StreamingProtocol)) + if ((Interface->Class == AUDIO_CSCP_AudioClass) && + (Interface->SubClass == AUDIO_CSCP_MIDIStreamingSubclass) && + (Interface->Protocol == AUDIO_CSCP_StreamingProtocol)) { return DESCRIPTOR_SEARCH_Found; } @@ -151,16 +155,17 @@ uint8_t DComp_NextMIDIStreamingInterface(void* CurrentDescriptor) */ uint8_t DComp_NextMIDIStreamingDataEndpoint(void* CurrentDescriptor) { - if (DESCRIPTOR_TYPE(CurrentDescriptor) == DTYPE_Endpoint) + USB_Descriptor_Header_t* Header = DESCRIPTOR_PCAST(CurrentDescriptor, USB_Descriptor_Header_t); + + if (Header->Type == DTYPE_Endpoint) { - uint8_t EndpointType = (DESCRIPTOR_CAST(CurrentDescriptor, - USB_Descriptor_Endpoint_t).Attributes & EP_TYPE_MASK); + USB_Descriptor_Endpoint_t* Endpoint = DESCRIPTOR_PCAST(CurrentDescriptor, USB_Descriptor_Endpoint_t); /* Check the endpoint type, break out if correct BULK type endpoint found */ - if (EndpointType == EP_TYPE_BULK) + if ((Endpoint->Attributes & EP_TYPE_MASK) == EP_TYPE_BULK) return DESCRIPTOR_SEARCH_Found; } - else if (DESCRIPTOR_TYPE(CurrentDescriptor) == DTYPE_Interface) + else if (Header->Type == DTYPE_Interface) { return DESCRIPTOR_SEARCH_Fail; } -- cgit v1.2.3
