This is the first week of September.

Finished stuffs:

[Pretend to be the HID device on the ARM9 board] Part done by Ka Chun

1. Flash in the latest kernal version, 2.6.3X (This was done by Ka Chun); Reason: To use usbgadget. The old kernal does not support feature of pretending the usb slave device. We cannot use the port provided by mini2440.
2. Play tricks on the kernal code. This is beacause not all ports can be used from the new kernal code. We have to edit it, enable features so that the correct hardware can be activated.
3. The touch screen was once not working. Ka Chun fixed this

[Windows platform]

1. Successfully hook the event to the application. Once the correct event is captured, we can perform winAPI to find out the handle of the window that throw us the event. HWND is useful as it acts as an unique identifier to provide rich information such as process ID, text on the window for us to analysis.
2. Indeed, the old method we have used is Polling but it wasted CPU resourses so much. To get rid of it, we once considered making use of just a typical single thread. I have written a simple program using hook with Cplusplus. However, the program terminated soon. That is why we have to turn in to GUI program. The GUI thread is supposed to run infinitely until it is killed by user.
3. Since the C sharp is used for GUI program. (The reason for not using C++ is that GUI C# provide more fancy interface for designing. C# provides more objects for GUI design.) The other issue will be the driver program, which supposed to be written in C language (To help communicating with low level device). Originally, Libusb-win32 was introduced as an API to send and read data from the USB device. After some searching from the NET, we found that a further improved version of Libusb is provided called LibUSBDotNet. .Net stands for C# GUI class.

[Things to be Developed soon]

1. Make sure bytes can be sent to the mini2440 and read from mini2440 correctly.
2. Study the QT extended on mini2440 (Time consuming)
3. Study the source code of the test program of the HID device.
