Description: CBC下写的串口编程，API函数实例
I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows. -CBC was under the serial programming API function examples I wish this site had been around when I was trying to figure out how to make serial communications work in Windows 95.

Description: rtbuf.c is an implementation of a buffering scheme using the POSIX realtime
features. Its aim is to provide smooth playback of MPEG audio streams
even on a very heavily loaded machine. It uses many advanced features
of the operating system:
- System V shared memory
- POSIX.1b realtime scheduling extensions
- POSIX.1b memory locking
- Sound Driver DMA buffer mapping into the user proces space
Make sure that you have enabled these features! The downside
of these features is that they can only be used if the process has
root permissions. Using realtime features is somewhat dangerous, since
a realtime process can eat all the CPU time, rendering the machine
unresponsive. So don t try this on your server!

Description: NAME: u2440mon.c
DESC: u2440mon entry point,menu,download
HISTORY:
Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2410X.
Mar.27.2002:purnnamu: DMA is enabled.
Apr.01.2002:purnnamu: isDownloadReady flag is added.
Apr.10.2002:purnnamu: - Selecting menu is available in the waiting loop.
So, isDownloadReady flag gets not needed
- UART ch.1 can be selected for the console.
Aug.20.2002:purnnamu: revision number change 0.2 -> R1.1
Sep.03.2002:purnnamu: To remove the power noise in the USB signal, the unused CLKOUT0,1 is disabled.

Description: 中断在系统设计中的应用非常广泛，可以说，硬件中断、软件中断无处不在，在WINCE下驱动开发更是如此，比如：按键中断、触摸屏中断、AUDIO中断、DMA中断.....等等，几乎含概每个模块。因此，了解中断的处理过程对驱动开发极其重要，下面对WINCE下的中断处理过程做一个简单介绍。-Interruption in the system design is very extensive, can be said that the hardware interrupt, software interrupt everywhere, in the driver development, especially under WINCE, for example: interrupt button, touch screen interrupt, AUDIO interrupt, DMA, such as interruption ..... and so on, almost with each module overview. Therefore, the understanding of treatment interruption-driven development process is extremely important, following the interruption of treatment under WINCE process to do a simple introduction.

Description: Very fast file transfer over the parallel port, using dma and fifo, fast and slow methods. It works in dos and windows. It works in nt , if you use a program to open the ports so as winio. I have achived rates of 750 kbytes/sec in the fifo mode. The dma max seems to be about 500 kbytes/sec. You must make your own special parallel cable. Directions are given in dmapara.txt. I used a flat cable with every second line a ground. The maximum length seems to be about 5 meters.
