Microchip PIC18F 设备驱动 LCD部分-PIC18F family some LCD driver

实现can总线的硬件布线图，在protel上直接打开即可，按此图的实物板已制出，可确保无误。-The realization of the hardware can bus wiring diagram, in Protel can directly open, this physical map has already been produced to ensure accuracy.

程序能够实现将十二位的二进制数5V对应fffH变换成一路0~5V的电压。 精度方面：在使用时上下波动范围大约是0~2fH能保证高位寄存器准确； 调试过程中遇到了一系列问题：（1）p0口的使用需接上拉电阻，内部没有带电阻；（2）调试的过程最好使用单步运行，以便于察看寄存器的内容；（3）对系统板不熟悉，一些硬件方面容易出问题，像口连接，电源、地的连接。（4）直流电源使用不准确，内部的各个电源输出是独立的，需要共地。 -procedures to achieve 12 to a binary number 5V counterparts fffH transform all the way into the 0- 5V voltage. Accuracy : the use of fluctuating ranges of 0 ~ 2fH can guarantee accurate high register; debugging process encountered a series of questions : (1) p0 I need to connect to the widening use of resistance, with no internal resistance; (2) the process of commissioning the best use of single-step operation, in order to inspect the contents of Register; (3) The right not familiar with the system board, Some hardware problems are likely to occur, such as connectors, power, and connectivity. (4) DC power supply use of inaccurate, all within the Power output is independent, to the total needs.

8051单片机串行读写EEPROM，24C02，本案例采用汇编编写。打包成函数，可直接调用。适合初学者学习。-8051 serial read and write EEPROM, 24C02, compilation of the preparation used in this case. Packaged into a function, can be directly invoked. Suitable for beginners to learn.

在lpc2114 上的ADS例子，是学习GUI 的好例子，上面还附带有protues仿真的工程-ADS in the lpc2114 example is a good example of learning GUI, the above also comes with protues simulation project

spi 翻译资料 7.2 SPI总线 SD卡信道由指令和数据位（起始位和结束位）组成，SPI信道由字节定向。 每一个指令或数据块由8位的字节和CS标志构成。类似SD卡协议, SPI通讯由 指令、响应和数据组成。全部的主机与SD卡之间的通信由主机控制。主机执行 每一跟CS标志为低的总线-spi Translation 7.2 SPI bus data channel from the SD card command and data bit (start bit and end bit) component, SPI channel directed by byte. Every command or data block from 8-bit bytes and CS constitute signs. SD card similar to the agreement, SPI communications from command, response and data components. All of the host and the communications between the SD card by the host control. Each host implementation with CS low marks for bus

ch375的USB驱动打印程序 很有用-ch375 printing process of the USB drive is useful

非常好用的大容量EEPROM存储器，带2线或3线SPI接口，带128字节高速缓存。-very handy, large capacity EEPROM memory, with two lines or three-wire SPI interface, with 128 byte cache.
