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.

用C51實(shí)現(xiàn)的拼音輸入法,這是改寫的網(wǎng)友 embuffalo、獨(dú)步上載在www.21ic.com自由發(fā)布區(qū)的由張凱原作的51上的拼音輸入法程序。 原作使用了一個(gè)二維數(shù)組用以查表，我認(rèn)為這樣比較的浪費(fèi)空間，而且每個(gè)字表的索引地址要手工輸入，效率不高。所以我用結(jié)構(gòu)體將其改寫了一下。就是大家現(xiàn)在看到的這個(gè)。 因?yàn)榇a比較的大，共有6,000多漢字，這樣就得要12,000 byte來(lái)存放GB內(nèi)碼，所以也是沒(méi)辦法的 :-( 編譯結(jié)果約為3000h,因?yàn)榇蟛糠质撬饕恚a優(yōu)化幾乎無(wú)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(dāng)于有1K的片上x(chóng)data)。條件有限，沒(méi)有上片試驗(yàn)，仿真而已。 打算將其移植到AVR上，但CodeAVRC與IAR EC++在結(jié)構(gòu)體、指針的定義使用上似乎與C51不太一樣，現(xiàn)在還未搞定。還希望在這方面有經(jīng)驗(yàn)的網(wǎng)友能給予指導(dǎo)。

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(qū)動(dòng) 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.
