【NUCLEO-F412ZG试用体验】实验二 驱显12864黑白串口LCD
参考GPIO_IOToggle实例，为了保留原代码模块的完整性，自己另设两个.h模块：selfGpio.h和12864.h，放在inc目录下。代码如下：
gpioSelf.h

}

main.c中加入设置io的模块
//GPIO Initial
void ioInit(void){
//Enable GPIO Clock (to be able to program the configuration registers)
LED1_GPIO_CLK_ENABLE();
LED2_GPIO_CLK_ENABLE();
LED3_GPIO_CLK_ENABLE();
//1=clk,2=dat,3=reg,4=res
LCD1_GPIO_CLK_ENABLE();
LCD2_GPIO_CLK_ENABLE();
LCD3_GPIO_CLK_ENABLE();
LCD4_GPIO_CLK_ENABLE();
//Configure IO in output push-pull mode to drive external LEDs
GPIO_InitStruct.Mode  = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull  = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
GPIO_InitStruct.Pin = LED1_PIN;
HAL_GPIO_Init(LED1_GPIO_PORT, &GPIO_InitStruct);
GPIO_InitStruct.Pin = LED2_PIN;
HAL_GPIO_Init(LED2_GPIO_PORT, &GPIO_InitStruct);
GPIO_InitStruct.Pin = LED3_PIN;
HAL_GPIO_Init(LED3_GPIO_PORT, &GPIO_InitStruct);
//1=clk,2=dat,3=reg,4=res
GPIO_InitStruct.Pin = LCD1_PIN;
HAL_GPIO_Init(LCD1_GPIO_PORT, &GPIO_InitStruct);
GPIO_InitStruct.Pin = LCD2_PIN;
HAL_GPIO_Init(LCD2_GPIO_PORT, &GPIO_InitStruct);
GPIO_InitStruct.Pin = LCD3_PIN;
HAL_GPIO_Init(LCD3_GPIO_PORT, &GPIO_InitStruct);
GPIO_InitStruct.Pin = LCD4_PIN;
HAL_GPIO_Init(LCD4_GPIO_PORT, &GPIO_InitStruct);
}

再加入
ioInit();
lcdInit();
就可以了，结果如下照片。此后在实验1款黑白和1款串口TFTLCD就完成显示实验了。
目前还没有弄明白8位并口或16位并口的设置和驱动方式。
