用C51實現的拼音輸入法,這是改寫的網友 embuffalo、獨步上載在www.21ic.com自由發布區的由張凱原作的51上的拼音輸入法程序。 原作使用了一個二維數組用以查表，我認為這樣比較的浪費空間，而且每個字表的索引地址要手工輸入，效率不高。所以我用結構體將其改寫了一下。就是大家現在看到的這個。 因為代碼比較的大，共有6,000多漢字，這樣就得要12,000 byte來存放GB內碼，所以也是沒辦法的 :-( 編譯結果約為3000h,因為大部分是索引表，代碼優化幾乎無效。 在Keil C里仿真芯片選用的是華邦的W77E58，它有32k ROM, 256B On-Chip RAM, 1K On-Chip SRAM (用DPTR1指針尋址,相當于有1K的片上xdata)。條件有限，沒有上片試驗，仿真而已。 打算將其移植到AVR上，但CodeAVRC與IAR EC++在結構體、指針的定義使用上似乎與C51不太一樣，現在還未搞定。還希望在這方面有經驗的網友能給予指導。

This program demonstrates operation of ADC0 in polled mode. The ADC0 is // configured to use writes to AD0BUSY as its start of conversion source and // to measure the output of the On-Chip temperature sensor. The temperature // sensor output is converted to degrees Celsius and is transmitted out UART0

ST7529液晶驅動 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an On-Chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, digital signal processor (DSP) families (hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. These processors also provide an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, On-Chip memory, and additional On-Chip peripherals. These DSP families also provide a highly specialized instruction set, which is the basis of the operational flexibility and speed of these DSPs.
