前几天手机排线坏了，到配件市场买排线，发现还有3310的屏买，12一块，想起来网上有过用单片机驱动3310的，就买了两块回来，今天终于把它弄好了，先上个图片，以验证真实性：






咱手机的摄像头不好，大家将就着看吧，想看清晰的，自己做吧，我给大家提供电路和程序。

   

小弟的硬件电路就是参照这些东西，第一个图是引脚线序，第二个图就是看了个4.7uf的电容，资料上说是调对比度的。
但是这个屏是3.3v，所以电源不要直接用5v，你可以加一个ASM1117，把5v降到3.3v就ok了。
程序如下：
  1. /*            3310液晶显示屏C51测试程序
  2.                  2004/07/31/BD2YA
  3. 接脚资料：
  4. Pin Signal Description Port
  5. 1:VDD
  6. Power Input. Logic supply voltage range VDD to GND : 2.7 to 3.3 V
  7. 2:SCLK
  8. Serial clock. Input for the clock signal: 0.0 to 4.0 Mbits/s.
  9. 3:SDIN
  10. Serial data. Input for the data line.
  11. 4:D/C
  12. Mode Select. To select either command/address or data input.
  13. 5:SCE
  14. Chip enable input. The enable pin allows data to be clocked in. The signal is active LOW.
  15. 6:GND
  16. Ground
  17. 7:VOUT
  18. Ouptut voltage. Add external 1-10 uF electrolytic capacitor from VOUT to GND
  19. 8:RES
  20. External reset. This signal will reset the device and must be applied to properly
  21. initialize the chip. The signal is active LOW.
  22. 控制芯片：
