有了上面的对OLED发送命令和写入显示数据到OLED的函数,我们就很可以随心所欲的操作OLED了：
首先我们将OLED到LPC1343的控制线和数据线都设置为输出状态。OLED里面的数据我不关心（里面数据乱了顶多重写），所以RDB的线我直接接高电平。
其次：初始化OLED。
最后：把OLED整屏刷成白色，验证OLED是否正常顺便检查一下有没有坏点。有兴趣的朋友还可以刷成其他颜色。修改最后的FOR循环就可以了。
初始化代码如下：
void oledinit(void)
{
//初始化GPIO口，让CSI、CSV、A0、RSB、WRB都为输出（DIR位=1）IO2_0:5为输出
//CSI=1、CSV=1、A0=0、RSB=1、WRB=1；
LPC_IOCON->PIO2_0=0x50;
LPC_IOCON->PIO2_1=0x50;
LPC_IOCON->PIO2_2=0x50;
LPC_IOCON->PIO2_3=0x50;
LPC_IOCON->PIO2_4=0x50;
LPC_IOCON->PIO2_5=0x50;
LPC_GPIO[2]->DIR |= 0x3f; //对应位为1输出
LPC_GPIO[2]->MASKED_ACCESS[0x3f] = 0x00; //data=0，OLED命令模式,这是安全的GPIO设置
LPC_IOCON->JTAG_TMS_PIO1_0=0xd1; //数字上拉，IO口
LPC_GPIO[1]->DIR |= 1; //对应位为1输出
LPC_GPIO[1]->MASKED_ACCESS[0x01] = 0x00; //A0=0，OLED命令模式,这是安全的GPIO设置
LPC_IOCON->JTAG_TDO_PIO1_1=0xd1; //数字上拉，IO口
LPC_GPIO[1]->DIR |= 2; //对应位为1输出
LPC_GPIO[1]->MASKED_ACCESS[0x02] = 0x02; //CSV=1，取消选中OLEDV,这是安全的GPIO设置}
LPC_IOCON->PIO1_5=0x50;
LPC_GPIO[1]->DIR |= 0x20; //对应位为1输出
LPC_GPIO[1]->MASKED_ACCESS[0x20] = 0x20; //WRB=1，不写,这是安全的GPIO设置
LPC_IOCON->PIO1_8=0x50;
LPC_GPIO[1]->DIR |= 0x100; //对应位为1输出
LPC_GPIO[1]->MASKED_ACCESS[0x100] = 0x100; //RSB=1，不写,这是安全的GPIO设置
LPC_IOCON->PIO3_0=0x50;
LPC_GPIO[3]->DIR |= 0x01; //对应位为1输出
LPC_GPIO[3]->MASKED_ACCESS[0x01] = 0x01; //CSI=1，取消选中OLEDI,这是安全的GPIO设置
//初始化显示OLED
//standby on/off
//LPC_GPIO[1]->MASKED_ACCESS[0x100] = 0x00;
//delay1(1000);
//LPC_GPIO[1]->MASKED_ACCESS[0x100] = 0x100;
