【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
#include "stm32f4xx_hal.h"
#define LCDn 4
//1=clk,2=dat,3=reg,4=res

#define LCD1_GPIO_CLK_DISABLE() __HAL_RCC_GPIOD_CLK_DISABLE()

#define LCD2_GPIO_PORT GPIOD
#define LCD2_GPIO_CLK_ENABLE() __HAL_RCC_GPIOD_CLK_ENABLE()
#define LCD2_GPIO_CLK_DISABLE() __HAL_RCC_GPIOD_CLK_DISABLE()

#define LCD3_GPIO_CLK_DISABLE() __HAL_RCC_GPIOD_CLK_DISABLE()
#define LCD4_PIN GPIO_PIN_7
#define LCD4_GPIO_PORT GPIOD
#define LCD4_GPIO_CLK_ENABLE() __HAL_RCC_GPIOD_CLK_ENABLE()
#define LCD4_GPIO_CLK_DISABLE() __HAL_RCC_GPIOD_CLK_DISABLE()
#define LCDx_GPIO_CLK_ENABLE(__INDEX__) do {if(( __INDEX__)==0){ __HAL_RCC_GPIOB_CLK_ENABLE();} else\
{ __HAL_RCC_GPIOB_CLK_ENABLE();}}while(0)
#define LCDx_GPIO_CLK_DISABLE(__INDEX__) do {if(( __INDEX__)==0){ __HAL_RCC_GPIOB_CLK_DISABLE();} else\
{ __HAL_RCC_GPIOB_CLK_DISABLE();}} while(0)
12864.h如下：

}
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。

main.c中加入设置io的模块
//GPIO Initial

LED1_GPIO_CLK_ENABLE();
LED2_GPIO_CLK_ENABLE();
LED3_GPIO_CLK_ENABLE();

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。

这是一个系列啊 ，小编真的很厉害
我只是想按照ARMmbed工具将基础内容走一遍，以便网友们尤其是新手们可以用较为简单的方法较快城市和掌握这类芯片和板子。谢谢
谢谢小编的回复 谢谢小编
