XSbase270
XSbase270 is a embedded portable application development platform base on PXA270 processor

QT Qt is a cross-platform application
development framework, widely used for the development of GUI(Graphical User Interface) programs.
Qt uses standard C++ to build programs.
We used Qt3 to build GUI applications.

QT The GUI programs can rapid build by QT
Designer tool.

Communicating with Hardware
Programming the FPGA device driver functions:
Open() Read() Write() Close()

Communicating with Hardware
FPGA register physical address define in fpga_reg_set.h
#define CS5_BASE_ADDR 0x14000000
#define SW_PHY_ADDR CS5_BASE_ADDR+0x20000
(read) #define LED_PHY_ADDR CS5_BASE_ADDR+0x0
(write)

Example The example is a the action recorder that can
record the buttons by clicking for you. Then it can click the replay button to release the steps.
