MIB的参考代码,有IDB_GET,IDB_SET,和IDB_NVM_SET的具体写法和说明-MIB reference code, IDB_GET, IDB_SET, and the specific wording IDB_NVM_SET and notes

WIN2000 版本JTAG使用说明，很详细，很有用-err

nuclues 内核源代码已经在arm7-9 上作了移植

该程序模块中xllp_CPUfreq.s，xllp_freq.c，xllp_intc.s，xllp_freq.h四个文件是修改CPU频率的主要代码，使用前可以将这些文件和xllp目录下的文件编译在一起，以便可以在程序的任何地方调用它们，修改和读取CPU频率主要依靠调用xllp_freq.c文件中的两个函数完成：XLLPSetCoreRunFrequency，xllpGetCurrentFreqSetting。其余代码只是一个调用这两个函数的一个例子，也可以自己重新写一个。为了简便，可以将所有的文件当作一个驱动程序在同一个目录下编译，然后以流驱动的方式加载，再用应用程序控制。

93c46(56,66)的读写程序,包含有读写一个字节，读写一字符串-93c46 (56,66) read and write procedures, contains a byte read and write, read and write a string, etc.

用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。 由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。 可以经过修改使用LPC2132以上的ARM的D/A来产生。 This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate the PWM voice. Voice data from the PC after the conversion. It is the largest of 16. Because there is PWM output ports need low-pass filter can be relatively clean voice. It has been modified over the use LPC2132 ARM D/A to produce. This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.
