stc+3310 ok.c

两个C51测试3310的源程序其中一个移植朋友网站上的AVR例程。芯片用STC89LE58RD+

/* 3310液晶显示屏C51测试程序 
接脚资料： 
Pin Signal Description Port 
1:VDD 
Power Input. Logic supply voltage range VDD to GND : 2.7 to 3.3 V 
2:SCLK 
Serial clock. Input for the clock signal: 0.0 to 4.0 Mbits/s. 
3:SDIN 
Serial data. Input for the data line. 
4:D/C 
Mode Select. To select either command/address or data input. 
5:SCE 
Chip enable input. The enable pin allows data to be clocked in. The signal is 
active LOW. 
6:GND 
Ground 
7:VOUT 
Ouptut voltage. Add external 1-10 uF electrolytic capacitor from VOUT to GND 
8:RES 
External reset. This signal will reset the device and must be applied to 
properly 
initialize the chip. The signal is active LOW.
