液晶诺基亚LCD3310驱动电路及程序

1、诺基亚3310液晶是一种OEM产品48X84 pixels matrix LCDcontroller/driver生产厂家 Philips, 型号为：PCD8544可显示84*48点,被评为性价比最好的AVR液晶3310lcd驱动电路:Vdd接3.3V（注意：工作电压是3.3V）或者如图接（1、接100欧姆电阻接5V 2、接二极管再接地）Vout接4.7uF电容后接地，电容作用是调对比度GND接地其它的接普通IO口编码显示原理：LCD3310屏幕由84*48个点组成，划分为84列*6行个显示单元，每一个显示单元由1*8个点组成，编程控制显示时按坐标定位，X轴从左到右为0、1、。83，Y轴从上到

2、下为0、1.。5，每一个显示单元用一个十六进制0x*控制，0x*转换成二进制后是8个01位，每一个显示单元从上到下为点1到点8，分别对应二进制数的最低到最高位，为1的显示黑点，为0的不显示下面将要讲到的字符显示是用六个连续的显示单元控制显示的，例如0x14,0x08,0x3E,0x08,0x14,0x00,   /将会显示符号 *0000000000110110110111111011011011001000000000000x14x08X3EX08X14X00所以我们可以自由的显示字母、汉字、图片，只要将对应的十六进制控制码写入LCD即可，汉字和图片的控制码可借助于专用的

3、字模生成软件生成。Pin Signal Description Port1:VDDPower Input. Logic supply voltage range VDD to GND : 2.7 to 3.3 V2:SCLKSerial clock. Input for the clock signal: 0.0 to 4.0 Mbits/s.3:SDINSerial data. Input for the data line.4:D/CMode Select. To select either command/address or data input.5:SCEChip enable in

4、put. The enable pin allows data to be clocked in. The signal is active LOW.6:GNDGround7:VOUTOuptut voltage. Add external 1-10 uF electrolytic capacitor from VOUT to GND8:RESExternal reset. This signal will reset the device and must be applied to properlyinitialize the chip. The signal is active LOW.
