PIC18F family some LCD driver

好东西，大家快来下，值得一看的东西，受益匪浅

avr单片机EEPROM读写程序 经过调试，已经成功进行读写-avr after single-chip EEPROM read and write debug procedures have been successfully read and write

实现I2C终线的功能，24C64的I2C的总工会系啊-I2C to achieve the function of the end line, 24C64, Department of Trade Unions of the I2C ah

AT91SAM9260 ARM9设计的网络收音机原理图与代码-AT91SAM9260 ARM9 Radio network design schematics and code

这是一个针对AVR单片机的串口编程，里面有原理图，加上串口源码。针对型号为ATMEGA128的AVR单片机使用。其它的芯片，如果寄存器一样也可套用。-This is a serial port for AVR MCU programming, which has schematic diagram, together with the serial code. ATmega128 model for single-chip using the AVR. Other chips, the same as if the register can also be applied.

芯片PCF8951共有四个A/D输入通道：AD0，AD1，AD2，AD3,分别与四个电位器(R1,R2,R3,R4)连接，用以调节电位器的输出电压。其中AD0通道既可测量电位器输出电压，也可用于测量从J1插座输入的外接电压，须用开关J2加以选择。J4插座提供由PCF8591输出的时钟方波信号。SAA1064驱动四个数码管显示一路AD转换后得到的数据。-PCF8951 chip, there are four A/D input channels: AD0, AD1, AD2, AD3, respectively, with four potentiometers (R1, R2, R3, R4) connected to regulate the output voltage potential. AD0 channel which can be measured potentiometer output voltage can also be used to measure the input from the J1 socket external voltage, to be used to select switch J2. J4 socket output from the PCF8591 clock square wave signal. SAA1064 drivers of four digital display along after AD conversion data.

本压缩文件主要介绍温度传感芯片的应用，及相关C程序，源代码直接可以使用-The compressed files are introduced chip temperature sensing applications, and related C program, source code can be used directly

6段数码管分别显示，时，分，秒，四个按键，K1（P0.0），K2（P0.1）， K3（P0.2），K4（P0.3），四个按键用来调时间的，按下K1，所有位都清零显示，然后按下K2，秒在闪烁，继续按K2分闪烁，不段地按K2 秒--分--时切换着闪烁，在某位闪时按下K3相应位加一，确认调整，按K4，取消调整再按K1。在K1按下以后才有调时的功能，如果K1没有按下，按别的键没有反映。这为了在加点按键功能留着用 -6 respectively of the digital control, when, minutes and seconds, four keys, K1 (P0.0). K2 (P0.1), K3 (P0.2), K4 (width), the four keys to the transfer time, press the K1, All spaces are reset, then press K2, the scintillation seconds, according to K2 pm flickered. not according to K2 of seconds-- minutes-- when switching to flicker in certain press the flash-K3 corresponding increase in a confirmed adjustment by K4, then canceled K1 adjustment. K1 in the press will only be made after the transfer of function, if K1 pressed by other key is not reflected. This points to the function keys used Retention

eeprom24c02程序代码，经测试可以使用，分享一下-eeprom24c02 program code, have been tested can use, share

网上找到的PCF8563程序基本不能用 本程序基于51单片机，模拟了I2C接口，现已调试成功，可以做成万年历了
