Description: USB Device Stack File This file contains functions, macros, definitions, variables, datatypes, etc. that are required for usage with the MCHPFSUSB device stack. This file should be included in projects that use the device stack. This file is located in the "\<Install Directory\>\\Microchip\\USB" directory. When including this file in a new project, this file can either be referenced from the directory in which it was installed or copied directly into the user application folder. If the first method is chosen to keep the file located in the folder in which it is installed then include paths need to be added so that the library and the application both know where to reference each others files. If the application folder is located in the same folder as the Microchip folder (like the current demo folders), then the following include paths need to be added to the application's project: . ..\\..\\MicrochipInclude If a different directory structure is used, modify the paths as required. An example using absolute paths instead of relative paths would be the following: C:\\Microchip Solutions\\Microchip\\Include C:\\Microchip Solutions\\My Demo Application ******************************************************************** File Description: Change History: Rev Description ---- ----------- 2.6 Added USBCancelIO() function. Moved and some stack defintions to be more consistant with the host stack. 2.6a Fixed issue where a SET_CONFIGURATION received could cause inability to transmit on an endpoint if using ping-pong and an odd number of packets had been sent on that endpoint 2.7 Fixed error where the USB error interrupt flag was not getting cleared properly for PIC32 resulting in lots of extra error interrupts. http://www.microchip.com/forums/tm.aspx?m=479085 Fixed issue with dual role mode when device run in polling mode. Interrupts were remaining enabled after the host mode operation was complete. This was incompatible with polling mode operation. Changed how the bus sensing works. In previous revisions it was impossible to use the USBDeviceDetach to detach from the bus if the bus voltage was still present. This is now possible. It was also possible to move the device to the ATTACHED state in interrupt mode even if the bus voltage wasn't available. This is now prohibited unless VBUS is present. Improved error case handling when the host sends more OUT bytes in a control transfer than the firmware was expecting to receive (based on the size parameter when calling USBEP0Receive()). In the USBStdSetCfgHandler(), modified the code so the USBDeviceState variable only gets updated to the CONFIGURED_STATE at the end of the function. 2.7a Update to support the PIC18F47J53 A1 and later revision devices. Fixed an error on 16-bit and 32-bit processors where a word access could be performed on a byte pointer resulting in possible address errors with odd aligned pointers. 2.8 Several changes to the way control transfers get processed, so as to support the ability to allow application/class specific handler code to defer the status stage. Implemented USBCtrlEPAllowStatusStage() API function. Implemented USBDeferStatusStage() API function (macro). These changes also greatly relax the USBDeviceTasks() calling frequency requirement, while allowing USB class handlers more flexibility. Also implemented the following API functions and macros, for delaying the data stage of a control transfer (with data stage): USBDeferINDataStage() USBDeferOUTDataStage() USBOUTDataStageDeferred() USBINDataStageDeferred() USBCtrlEPAllowDataStage() Fixed USB reset event handler issue, where the USB stack would re-initialize global interrupt settings in the interrupt context, on PIC18 devices with the stack operated in USB_INTERRUPT mode. Fixed handling of SET/CLEAR FEATURE (endpoint halt) host requests. Previous implementation would not always initialize endpoints correctly to DATA0 DTS state after a clear feature endpoint halt request, for all ping pong mode and usage scenarios. ********************************************************************/ /*---------------------------------------------------------------------------------- The USBDeviceTasks() function is responsible for detecting and processing various USB bus events and host requests, such as those required for USB enumeration, when the USB cable is first attached to the host. This function is the main dispatcher routine for the USB stack. Additional API functions and macros are also provided by the USB stack, which can be used to send/receive USB data to/from the host, among other things. A full list of the available implemented functions/macros are provided in the "MCHPFSUSB Library Help". For normal installations of the MCHPFSUSB Framework, the USB API documentation can be found from: Start menu --> (All Programs) --> Microchip --> MCHPFSUSB vX.x --> Documents --> MCHPFSUSB Library Help Once the help file is opened, the API functions/macros are described in the following section: Library
