This program prints the C8051F124 die temperature out the hardware UART at 115200bps. This example uses the internal 24.5MHz oscillator multiplied by 2 using the on-chip PLL (SYSCLK = 49MHz).

This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, controlling on-chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.

YSS915 (KP2V2) is an LSI for processing Karaoke voice signals. This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that YSS915 is applicable to various uses. In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the surround effect is applied to the movie and music sources for giving the users more enjoyment. YSS915 is pin compatible with and register compatible with YSS903 (KP2V).

用C51实现的拼音输入法,这是改写的网友 embuffalo、独步上载在www.21ic.com自由发布区的由张凯原作的51上的拼音输入法程序。 原作使用了一个二维数组用以查表，我认为这样比较的浪费空间，而且每个字表的索引地址要手工输入，效率不高。所以我用结构体将其改写了一下。就是大家现在看到的这个。 因为代码比较的大，共有6,000多汉字，这样就得要12,000 byte来存放GB内码，所以也是没办法的 :-( 编译结果约为3000h,因为大部分是索引表，代码优化几乎无效。 在Keil C里仿真芯片选用的是华邦的W77E58，它有32k ROM, 256B on-chip RAM, 1K on-chip SRAM (用DPTR1指针寻址,相当于有1K的片上xdata)。条件有限，没有上片试验，仿真而已。 打算将其移植到AVR上，但CodeAVRC与IAR EC++在结构体、指针的定义使用上似乎与C51不太一样，现在还未搞定。还希望在这方面有经验的网友能给予指导。

ARM7硬件说明与开发 The ARM7 is a low-power, general purpose 32-bit RISC microprocessor macrocell for use in application or customer-specific integrated circuts (ASICs or CSICs). Its simple, elegant and fully static design is particularly suitable for cost and power-sensitive applications. The ARM7’s small die size makes it ideal for integrating into a larger custom chip that could also contain RAM, ROM, logic, DSP and other cells.
