Far too many programmers and software designers consider efficient C++ to be an oxymoron. They regard C++ as inherently slow and inappropriate for performancecritical applications. Consequently, C++ has had little success penetrating domains such as networking, operating system kernels, device driverS, and others.

This example program is the source code for the FT232BM Test Application from our Utilities page. It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test cable shown on ST_232_245.pdf to be connected. Our D2XX direct driverS should be installed for this application. The code can be modified to fit your requirements. To download the application source code , click here. To download the test cable specification, click here.

在大多2440开发板BSP中的SMDK2440\driverS\backlite目录下一般都有背光驱动。在注册表中添加如下函数的时候,开机时确实可以打印"!!!!!!!!!!!! BACKLIGHT ON !!!!!!!!!!!!,如果没有操作大概1分钟后也可以打印!!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!。但打印("!!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!后,就算有触发事件(在触摸屏上点击,或者移动鼠标)也不会打印"!!!!!!!!!!!! BACKLIGHT ON !!!!!!!!!!!!。 其实这个驱动大体是正确的,只是当键盘鼠标或触摸屏输入时候gwes 发送“PowerManager/ActivityTimer/UserActivity” event,而不是原驱动中的“("UserInputEvent") ”修改后的源程序如下(SMDK2440\driverS\backlite目录下bak_hw.cpp文件)。

C++ is widely used in the software industry. Some of its application domains include systems software, application software, device driverS, embedded software, high-performance server and client applications, and entertainment software such as video games. Several groups provide both free and proprietary C++ compiler software, including the GNU Project, Microsoft, Intel, Borland and others.
