-----------------------------------
USB Bulk Example (usb_bulk_example)
-----------------------------------
This Windows command line application is written using C for Windows
and should be built using Microsoft Visual Studio 2010. Project
file usb_bulk_example.vxcproj is provided to build the application.
USB communication with the board running the usb_dev_bulk sample application
is performed using the TIUSBDLL interface which is a thin wrapper over the
Microsoft WinUSB API. The relevant WinUSB subsystem files and the
TIUSBDLL.dll are installed when you first connect the board to a Windows
host via USB and install the drivers. Device drivers for the usb_dev_bulk
device can be found in the MWare\windows_drivers directory.
The TIUSBDLL interface is provided purely to allow the sample applications
to be compiled and run in the absence of the Windows Device Driver Kit
(DDK). The WinUSB API header and library files are not included in the
Windows SDK shipped with Visual Studio 2010 so any code which uses this
interface requires access to the DDK to build. TIUSBDLL contains all
the application code requiring WinUSB so applications may link to it
without the need for the Windows DDK.

//
// FILE: usb_bulk_example.c
//
// TITLE: A very simple command line application that attempts
// to open the TI Generic Bulk USB device and exchange data
// with it.
//
// If the device is successfully opened, the user is prompted for a string
// which is then sent to the device. The device toggles the case of any
// alphabet characters in the the data and sends it back. We receive this
// and print out the result.
//
// Communication with the device is carried out via a simple DLL, tiusbdll(64),
// which is responsible for opening and closing the device and for
// sending and receiving blocks of data. This structure allows the
// application code to be kept independent of the underlying USB driver
// in use. In this implementation, Microsoft's WinUSB interface is used
// but a switch to another stack, for example the open source libusb-win32
// interface could be made merely be replacing the tiusbdll(64).dll with
// another version writing to the different USB stack.
//
// One downside to using WinUSB is that it requires you to have the Windows
// Device Driver Kit (DDK) installed to build applications which use the
// interface. This is a very large download making it awkward for people
// with slow internet connections. The use of tiusbdll(64).dll also offers
// the advantage that applications using it can still be modified and
// rebuilt even without the DDK installed on the development system. To
// update and rebuild tiusbdll itself, however, the DDK is still required.

// FILE: usb_bulk_example_throughput.c
//
// TITLE: A very simple command line application that attempts
// to open the TI Generic Bulk USB device and exchange data
// with it.
//
// If the device is successfully opened, then data is sent continuously.
//
// Communication with the device is carried out via a simple DLL, tiusbdll(64),
// which is responsible for opening and closing the device and for
// sending and receiving blocks of data. This structure allows the
// application code to be kept independent of the underlying USB driver
// in use. In this implementation, Microsoft's WinUSB interface is used
// but a switch to another stack, for example the open source libusb-win32
// interface could be made merely be replacing the tiusbdll(64).dll with
// another version writing to the different USB stack.
//
// One downside to using WinUSB is that it requires you to have the Windows
// Device Driver Kit (DDK) installed to build applications which use the
// interface. This is a very large download making it awkward for people
// with slow internet connections. The use of tiusbdll(64).dll also offers
// the advantage that applications using it can still be modified and
// rebuilt even without the DDK installed on the development system. To
// update and rebuild tiusbdll itself, however, the DDK is still required.

//! \param pcString is the format string.
//! \param vaArgP is a variable argument list pointer whose content will depend

//! This function is very similar to the C library <tt>vprintf()</tt> function.
//! All of its output will be sent to the SCI. Only the following formatting
//! characters are supported:
//!
//! - \%c to print a character
//! - \%d or \%i to print a decimal value
//! - \%l to print a long decimal value
//! - \%s to print a string
//! - \%u to print an unsigned decimal value
//! - \%x to print a hexadecimal value using lower case letters
//! - \%X to print a hexadecimal value using lower case letters (not upper case
//! letters as would typically be used)
//! - \%p to print a pointer as a hexadecimal value
//! - \%\% to print out a \% character
//!
//! For \%s, \%d, \%i, \%u, \%p, \%x, and \%X, an optional number may reside
//! between the \% and the format character, which specifies the minimum number
//! of characters to use for that value; if preceded by a 0 then the extra
//! characters will be filled with zeros instead of spaces. For example,

//! added to reach eight; ``\%08d'' will use eight characters as well but will
//! add zeroes instead of spaces.

//*****************************************************************************
//
//! A simple SCI based printf function supporting \%c, \%d, \%p, \%s, \%u,
//! \%x, and \%X.
//!
//! \param pcString is the format string.
//! \param ... are the optional arguments, which depend on the contents of the
//! format string.
//!
//! This function is very similar to the C library <tt>fprintf()</tt> function.
//! All of its output will be sent to the SCI. Only the following formatting
//! characters are supported:
//!
//! - \%c to print a character
//! - \%d or \%i to print a decimal value
//! - \%s to print a string
//! - \%u to print an unsigned decimal value
//! - \%x to print a hexadecimal value using lower case letters
//! - \%X to print a hexadecimal value using lower case letters (not upper case
//! letters as would typically be used)
//! - \%p to print a pointer as a hexadecimal value
//! - \%\% to print out a \% character
//!
//! For \%s, \%d, \%i, \%u, \%p, \%x, and \%X, an optional number may reside
//! between the \% and the format character, which specifies the minimum number
//! of characters to use for that value; if preceded by a 0 then the extra
//! characters will be filled with zeros instead of spaces. For example,
//! ``\%8d'' will use eight characters to print the decimal value with spaces
//! added to reach eight; ``\%08d'' will use eight characters as well but will
//! add zeroes instead of spaces.
//!
//! The type of the arguments after \e pcString must match the requirements of
//! the format string. For example, if an integer was passed where a string
//! was expected, an error of some kind will most likely occur.
//!
//! \return None.

-----------------------------------
USB Bulk Example (usb_bulk_example)
-----------------------------------
This Windows command line application is written using C for Windows
and should be built using Microsoft Visual Studio 2010. Project
file usb_bulk_example.vxcproj is provided to build the application.
USB communication with the board running the usb_dev_bulk sample application
is performed using the TIUSBDLL interface which is a thin wrapper over the
Microsoft WinUSB API. The relevant WinUSB subsystem files and the
TIUSBDLL.dll are installed when you first connect the board to a Windows
host via USB and install the drivers. Device drivers for the usb_dev_bulk
device can be found in the MWare\windows_drivers directory.
The TIUSBDLL interface is provided purely to allow the sample applications
to be compiled and run in the absence of the Windows Device Driver Kit
(DDK). The WinUSB API header and library files are not included in the
Windows SDK shipped with Visual Studio 2010 so any code which uses this
interface requires access to the DDK to build. TIUSBDLL contains all
the application code requiring WinUSB so applications may link to it
without the need for the Windows DDK.

// FILE: usb_bulk_example.c
//
// TITLE: A very simple command line application that attempts
// to open the TI Generic Bulk USB device and exchange data
// with it.
//
// If the device is successfully opened, the user is prompted for a string
// which is then sent to the device. The device toggles the case of any
// alphabet characters in the the data and sends it back. We receive this
// and print out the result.
//
// Communication with the device is carried out via a simple DLL, tiusbdll(64),
// which is responsible for opening and closing the device and for
// sending and receiving blocks of data. This structure allows the
// application code to be kept independent of the underlying USB driver
// in use. In this implementation, Microsoft's WinUSB interface is used
// but a switch to another stack, for example the open source libusb-win32
// interface could be made merely be replacing the tiusbdll(64).dll with
// another version writing to the different USB stack.
//
// One downside to using WinUSB is that it requires you to have the Windows
// Device Driver Kit (DDK) installed to build applications which use the
// interface. This is a very large download making it awkward for people
// with slow internet connections. The use of tiusbdll(64).dll also offers
// the advantage that applications using it can still be modified and
// rebuilt even without the DDK installed on the development system. To
// update and rebuild tiusbdll itself, however, the DDK is still required.

// FILE: usb_bulk_example_throughput.c
//
// TITLE: A very simple command line application that attempts
// to open the TI Generic Bulk USB device and exchange data
// with it.
//
// If the device is successfully opened, then data is sent continuously.
//
// Communication with the device is carried out via a simple DLL, tiusbdll(64),
// which is responsible for opening and closing the device and for
// sending and receiving blocks of data. This structure allows the
// application code to be kept independent of the underlying USB driver
// in use. In this implementation, Microsoft's WinUSB interface is used
// but a switch to another stack, for example the open source libusb-win32
// interface could be made merely be replacing the tiusbdll(64).dll with
// another version writing to the different USB stack.
//
// One downside to using WinUSB is that it requires you to have the Windows
// Device Driver Kit (DDK) installed to build applications which use the
// interface. This is a very large download making it awkward for people
// with slow internet connections. The use of tiusbdll(64).dll also offers
// the advantage that applications using it can still be modified and
// rebuilt even without the DDK installed on the development system. To
// update and rebuild tiusbdll itself, however, the DDK is still required.

//!
//! \param pcString is the format string.
//! \param vaArgP is a variable argument list pointer whose content will depend
//! upon the format string passed in \e pcString.
//!
//! This function is very similar to the C library <tt>vprintf()</tt> function.
//! All of its output will be sent to the SCI. Only the following formatting
//! characters are supported:
//!
//! - \%c to print a character
//! - \%d or \%i to print a decimal value
//! - \%l to print a long decimal value
//! - \%s to print a string
//! - \%u to print an unsigned decimal value
//! - \%x to print a hexadecimal value using lower case letters
//! - \%X to print a hexadecimal value using lower case letters (not upper case
//! letters as would typically be used)
//! - \%p to print a pointer as a hexadecimal value
//! - \%\% to print out a \% character
//!
//! For \%s, \%d, \%i, \%u, \%p, \%x, and \%X, an optional number may reside
//! between the \% and the format character, which specifies the minimum number
//! of characters to use for that value; if preceded by a 0 then the extra
//! characters will be filled with zeros instead of spaces. For example,
//! ``\%8d'' will use eight characters to print the decimal value with spaces
//! added to reach eight; ``\%08d'' will use eight characters as well but will
//! add zeroes instead of spaces.
//!
//! The type of the arguments in the variable arguments list must match the
//! requirements of the format string. For example, if an integer was passed
//! where a string was expected, an error of some kind will most likely occur.
//!
//! \return None.

-----------------------------------
USB Bulk Example (usb_bulk_example)
-----------------------------------
This Windows command line application is written using C for Windows
and should be built using Microsoft Visual Studio 2010. Project
file usb_bulk_example.vxcproj is provided to build the application.
USB communication with the board running the usb_dev_bulk sample application
is performed using the TIUSBDLL interface which is a thin wrapper over the
Microsoft WinUSB API. The relevant WinUSB subsystem files and the
TIUSBDLL.dll are installed when you first connect the board to a Windows
host via USB and install the drivers. Device drivers for the usb_dev_bulk
device can be found in the MWare\windows_drivers directory.
The TIUSBDLL interface is provided purely to allow the sample applications
to be compiled and run in the absence of the Windows Device Driver Kit
(DDK). The WinUSB API header and library files are not included in the
Windows SDK shipped with Visual Studio 2010 so any code which uses this
interface requires access to the DDK to build. TIUSBDLL contains all
the application code requiring WinUSB so applications may link to it
without the need for the Windows DDK.

//
// TITLE: A very simple command line application that attempts
// to open the TI Generic Bulk USB device and exchange data
// with it.
//
// If the device is successfully opened, the user is prompted for a string
// which is then sent to the device. The device toggles the case of any
// alphabet characters in the the data and sends it back. We receive this
// and print out the result.
//
// Communication with the device is carried out via a simple DLL, tiusbdll(64),
// which is responsible for opening and closing the device and for
// sending and receiving blocks of data. This structure allows the
// application code to be kept independent of the underlying USB driver
// in use. In this implementation, Microsoft's WinUSB interface is used
// but a switch to another stack, for example the open source libusb-win32
// interface could be made merely be replacing the tiusbdll(64).dll with
// another version writing to the different USB stack.
//
// One downside to using WinUSB is that it requires you to have the Windows
// Device Driver Kit (DDK) installed to build applications which use the
// interface. This is a very large download making it awkward for people
// with slow internet connections. The use of tiusbdll(64).dll also offers
// the advantage that applications using it can still be modified and
// rebuilt even without the DDK installed on the development system. To
// update and rebuild tiusbdll itself, however, the DDK is still required.
