CUP芯片c8051F005,型号为LCM09CY的8段式段式显示器显示程序-CUP chip, the models for the eight LCM09CY Segment Segment Display procedures

51单片机的源程序集，有存储器，点阵式液晶，进制转换，led,ad等。-51 SCM source collection, storage, dot-matrix LCD, the base for the conversion, led, ad so.

按键扫描 51单片机加8279 8279通过74LS 138译码器扩展4×4键盘、6位显示器。 由3-8译码器对SL0～SL2译出键扫描线，由另一3-8译码器译出显示器的位扫描线，并采用了编码扫描方式。 为了防止出现重键现象，扫描输出线高位SL3不参加键扫描译码。CPU对8279的监视采用了查询方式，故8279的中断请求信号IRQ悬空未用。 -Scan button 82,798,279 plus 51 single-chip decoder 74LS 138 through the expansion of 4 × 4 keyboard, the display 6. From 3-8 decoder SL0 ~ SL2 translated to the key scanning line, by another 3-8 decoder translated display scan line, and uses code scanning. In order to prevent the emergence of the phenomenon of re-key, scan the output line does not take part in high level SL3 scan decoding keys. CPU on the 8279 surveillance using the query mode, the 8279 interrupt request signal IRQ left unused.

标准NEC格式红外发送库文件，AVR平台，开发环境中提取，拿来就用。-The standard NEC format for infrared send the library file, AVR platform, development environment to extract, brought to use.

atmega32 和RS485的通讯，已经在电路板上测试通过，RS232相对简单一点，RS485需要对控制收发信号处理一下，并且需要RS232转RS485工具来验证收发是否正确-atmega32 and RS485 communication, has been tested in the circuit board, RS232 relatively simple point, RS485 transceiver control signals need to deal with you, and will need RS232 to RS485 transceiver tools to verify the correctness of

本库函数为大容量(2M)Flash SST25VF016B的驱动函数 包括IO模拟SPI总线方式和C8051F020硬件SPI方式下的驱动 函数接口简单易用 代码规范简洁-The library functions for large-capacity (2M) Flash SST25VF016B driver function including IO simulation SPI bus mode and SPI mode C8051F020 hardware driver function interface specification concise easy-to-use code

这是一个实现利用gsm模块通信的visual basic 源程序-This is a system to use the gsm module communications, visual basic source code
