STM32-HAL库07-软件SPI驱动0.96寸OLED
STM32-HAL库07-软件SPI驱动0.96寸OLED
一、所用材料：
STM32VGT6自制控制板
STM32CUBEMX（HAL库软件）
MDK5
二、所学内容：
通过HAL库配置四个GPIO输出口，对其进行软件模拟SPI发送规则，进而驱动OLED进行数字或字母显示，暂不设计中文文字显示。
三、CUBEMX配置：
第一步：选取四个模拟GPIO输出引脚
第二步：配置SYS
第三步：配置RCC
第四步：配置时钟
第五步：文件配置
四、MDK5程序编写：
1.配置OLED.h文件
#ifndef __OLED_H
#define __OLED_H
//========移植的时候，根据所选芯片引入相应的头文件==========，在main.h里面查看
#include "stm32f4xx_hal.h"
#include "gpio.h"
//OLED模式设置
//0:4线串行模式
//1:并行8080模式
#define OLED_MODE 0
#define SIZE 16
#define XLevelL 0x00
#define XLevelH 0x10
#define Max_Column 128
#define Max_Row 64
#define Brightness 0xFF
#define X_WIDTH 128
#define Y_WIDTH 64
//========移植的时候，根据引脚分配进行修改==========
//使用4线串行接口时使用
//RES
#define OLED_RST_Clr() HAL_GPIO_WritePin(OLED_RST_GPIO_Port, OLED_RST_Pin, GPIO_PIN_RESET) //RES RES => 接RES（RST）引脚
#define OLED_RST_Set() HAL_GPIO_WritePin(OLED_RST_GPIO_Port, OLED_RST_Pin, GPIO_PIN_SET)
//DC
#define OLED_DC_Clr() HAL_GPIO_WritePin(OLED_DC_GPIO_Port, OLED_DC_Pin, GPIO_PIN_RESET)
#define OLED_DC_Set() HAL_GPIO_WritePin(OLED_DC_GPIO_Port, OLED_DC_Pin, GPIO_PIN_SET)
//SCLK,D0
#define OLED_SCLK_Clr() HAL_GPIO_WritePin(OLED_SCL_GPIO_Port, OLED_SCL_Pin, GPIO_PIN_RESET)
#define OLED_SCLK_Set() HAL_GPIO_WritePin(OLED_SCL_GPIO_Port, OLED_SCL_Pin, GPIO_PIN_SET)
//SDIN,D1
#define OLED_SDIN_Clr() HAL_GPIO_WritePin(OLED_SDA_GPIO_Port, OLED_SDA_Pin, GPIO_PIN_RESET)
#define OLED_SDIN_Set() HAL_GPIO_WritePin(OLED_SDA_GPIO_Port, OLED_SDA_Pin, GPIO_PIN_SET)
#define OLED_CMD 0 //写命令
#define OLED_DATA 1 //写数据
//OLED控制用函数
void OLED_WR_Byte(unsigned char dat,unsigned char cmd);
void OLED_Display_On(void);
void OLED_Display_Off(void);
void OLED_Init(void);
void OLED_Clear(void);
void OLED_DrawPoint(unsigned char x,unsigned char y,unsigned char t);
void OLED_Fill(unsigned char x1,unsigned char y1,unsigned char x2,unsigned char y2,unsigned char dot);
void OLED_ShowChar(unsigned char x,unsigned char y,unsigned char chr);
void OLED_ShowNum(unsigned char x,unsigned char y,unsigned long num,unsigned char len,unsigned char size);
void OLED_Showint (unsigned char x,unsigned char y,unsigned long num);
void OLED_ShowString(unsigned char x,unsigned char y, unsigned char *p);
void OLED_Set_Pos(unsigned char x, unsigned char y);
void OLED_ShowCHinese(unsigned char x,unsigned char y,unsigned char no);
void OLED_DrawBMP(unsigned char x0, unsigned char y0,unsigned char x1, unsigned char y1,unsigned char BMP[]);
#endif
2.配置OLED.c文件
#include
