/* 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.
