Code Red Technologies RDB1768 Board - USB Stack and Examples ============================================================ The USB stack and associated examples provided with RDB1768 board are based on the open source LPCUSB stack, originally written for the NXP LPC214x microcontrollers. The original sources for the USB stack and and examples can be found at: http://sourceforge.net/projects/lpcusb/ with additional information at: http://wiki.sikken.nl/index.php?title=LPCUSB We have tried to keep the changes to the codebase down to a minimum, and have commented where changes have been made as much as possible The USB projects also use the 'semihosting' option in the debug configuration so that 'printf' messages from the target are reported in the Red Suite Console Window. USBstack -------- This is the main project which builds the LPCUSB stack as a library. This is then used in building the various USB examples detailed below. USB_HID Example --------------- This is the standard LPCUSB Human Interface Device example, ported to the LPC1768/RDB1768. The example provides a simple HID driver. When executed on the RDB1768, this will register itself with the connected PC as a joystick (games controller). This can be seen by looking in the Windows Device Manager in System Properties. USB_HID_Mouse ------------- This example is based on the LPCUSB USB_HID example, but has been extended so that the RDB1768 will act as a mouse to the connected PC. To move the cursor, use the joystick on the RDB1768 board. Clicking on the joystick will act as pressing the mouse's left button. USB_MSC Example --------------- This is the standard LPCUSB mass storage device example, ported to the LPC1768/RDB1768. This example turns the RDB1768 into a mass storage device, by connecting the onboard micro-SD card system to USB sub-system via the SPI interface of the LPC1768. When the example is downloaded and run, the board will appear within Windows as a mass storage drive, which can be read from and written to as required. Note that you will require a micro-SD card to make use of this example. This should be inserted into the socket underneath the RDB1768's LCD screen before executing the example. Hot-plugging of cards is not supported. USB_Serial Example ------------------ This example provides a minimal implementation of a USB serial port, using the CDC class. This therefore allows you to connect to the board over USB from a terminal program, such as hyperterminal. By default this port of the example will simply echo everything it receives right back to the host PC, but incremented by 1. Thus if you type 'a' on the host PC, the program will send back 'b'. The original behaviour of echoing back the same character ('a' is sent back when 'a' was received) can be restored by changing the value of the #define of 'INCREMENT_ECHO_BY' from '1' to '0'. In order to connect to the board from hyperterminal, or similar, you will need to extract the usbser.sys file from .cab file in C:\WINDOWS\Driver Cache\i386 and store it somewhere (C:\temp is a good place) along with the usbser.inf file (provided as part of USB_Serial project). Then plug the USB cable into the USB device port of the RDB1768 and when requested (after downloading and starting execution of the example) direct Windows to the usbser driver. Windows then creates an extra COMx port that you can open in hyperterminal (or similar). When configuring your terminal program, you should set it to append line feeds to incoming line ends, and to echo typed characters locally. You will then be able to see the character you type, as well as the character returned by the example running on the board.
