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LPC213X系列的PWM來產(chǎn)生語音。語音數(shù)據(jù)來源于PC機(jī)轉(zhuǎn)換后得到的。最大可以是16位的。 由于是PWM所以輸出端口需要低通濾波才能夠得到比較干凈的聲音。 可以經(jīng)過修改使用LPC2132以上的ARM的D/A來產(chǎn)生。 This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

This project is created using the Keil ARM CA Compiler. The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1 This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series. You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.

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).

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。 因?yàn)榇a比較的大，共有6,000多漢字，這樣就得要12,000 byte來存放GB內(nèi)碼，所以也是沒辦法的 :-( 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xdata)。條件有限，沒有上片試驗(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 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.
