5.0 6800并口协议
提到 "6800"，最著名的可能是 Motorola 6800 微处理器。这是由摩托罗拉公司在1974年发布的8位微处理器，它在当时的计算机和嵌入式系统中扮演了重要角色。
6.0 8080并口协议
7.0 4线SPI
8.0 3线SPI
9.0 0.96寸显示屏命令表
10.0 开启指令
11.0 IIC通讯协议
注：IIC协议实现参考这一篇文章：STM32 IIC协议实现-CSDN博客
12.0 程序实现
12.0.1 发送命令
// OLED发送命令
void OLED_WriteCommand(uint8_t command)
{IIC_Start();IIC_SendByte(0x78);IIC_Wait_Ack();IIC_SendByte(0x00);IIC_Wait_Ack();IIC_SendByte(command);IIC_Wait_Ack();IIC_Stop();
}12.0.2 发送数据
// OLED发送数据
void OLED_WriteData(uint8_t data)
{IIC_Start();IIC_SendByte(0x78);IIC_Wait_Ack();IIC_SendByte(0x40);MyI2C_ReceiveAck();IIC_SendByte(data);IIC_Wait_Ack();IIC_Stop();
}12.0.3 设置显示位置
注：以上的内容来自元地址设置命令表，表示x坐标的位置和Y坐标的位置
// OLED显示位置
void OLED_SetCursor(uint8_t x, uint8_t page)
{// 设置显示的X轴低四位OLED_WriteCommand(0x00 | (x & 0x0F));// 设置显示的X地址高四位OLED_WriteCommand(0x10 | (x & 0xF0) >> 4);// 设置显示的页地址OLED_WriteCommand(0xB0 | page);
}12.0.4 初始化OLED
注：这个操作也就是开启显示器的显示，将显示器从关闭状态转换为打开状态
// 初始化OLED
void OLED_Init(void)
{// 初始化IICIIC_Init();Delay_ms(100);OLED_WriteCommand(0xAE);OLED_WriteCommand(0xD5);OLED_WriteCommand(0x80);OLED_WriteCommand(0xA8);OLED_WriteCommand(0x3F);OLED_WriteCommand(0xD3);OLED_WriteCommand(0x00);OLED_WriteCommand(0x40);OLED_WriteCommand(0xA1);OLED_WriteCommand(0xC8);OLED_WriteCommand(0xDA);OLED_WriteCommand(0x12);OLED_WriteCommand(0x81);OLED_WriteCommand(0xCF);OLED_WriteCommand(0xD9);OLED_WriteCommand(0xF1);OLED_WriteCommand(0xDB);OLED_WriteCommand(0x30);OLED_WriteCommand(0xA4);OLED_WriteCommand(0xA6);OLED_WriteCommand(0x8D);OLED_WriteCommand(0x14);OLED_WriteCommand(0xAF);Delay_ms(100);
}12.0.5 清屏函数
// OLED 清屏
void OLED_Clear(void)
{for (uint8_t j = 0; j < 8; j++){OLED_SetCursor(0, j);{for (uint8_t i = 0; i < 128; i++){OLED_WriteData(0x00);}}}
}12.0.6 OLED显示字符
// OLED显示字符
void OLED_ShowChar(uint8_t x, uint8_t y, char mChar, uint8_t fontSize)
{if (fontSize == 8){// 设置起始位置OLED_SetCursor(x, y);uint8_t i = 0;for (i = 0; i < 8; i++){// 写入数组指定行的第i个数据OLED_WriteData(ascii8x16[mChar - ' '][i]);}OLED_SetCursor(x, y + 1);for (i = 0; i < 8; i++){OLED_WriteData(ascii8x16[mChar - ' '][i + 8]);}}
}12.0.7 OLED显示字符串
void OLED_ShowString(uint8_t X, uint8_t Page, char *String, uint8_t FontSize)
{for (uint8_t i = 0; String[i] != '\0'; i++){OLED_ShowChar(X + i * FontSize, Page, String[i], FontSize);}
}12.0.8 OLED显示图片
// OLED显示图片
void OLED_ShowImage(uint8_t x, uint8_t y, uint8_t width, uint8_t height, const uint8_t *Image)
{for (uint8_t j = 0; j < height; j++){// 设置起始位置OLED_SetCursor(x, y + j);uint8_t i = 0;for (i = 0; i < width; i++){// 写入数组指定行的第i个数据OLED_WriteData(Image[width * j + i]);}}
}/*** @brief 补充注释* 如果高度是1也就是只有8个像素，也就是只有一页* 那么显示一页的数据就是遍历width页就是字符的宽度个字节* 然后显示对应的数。* 如果高度不仅仅是1而是16，也就是代表这个字符是跨2页进行* 写入的，那么就要再加一个for循环对第二页的数据进行写入* 也就是第二页开始的字节然后写入【0-9】【】**/12.0.9 OLED显示汉字
void OLED_ShowChinese(uint8_t X, uint8_t Page, char *Chinese)
{// 第一步：先把传递过来的汉字串，拆分为一个个独立的汉字char SigleChinese[4] = {0};uint8_t pChinese = 0;uint8_t pIndex;for (uint8_t i = 0; Chinese[i] != '\0'; i++){SigleChinese[pChinese] = Chinese[i];pChinese++;if (pChinese >= 3){pChinese = 0;for (pIndex = 0; strcmp(OLED_CF16x16[pIndex].Index, "") != 0; pIndex++){if (strcmp(OLED_CF16x16[pIndex].Index, SigleChinese) == 0){break;}}OLED_ShowImage(X + ((i + 1) / 3 - 1) * 16, Page, 16, 2, OLED_CF16x16[pIndex].Data);}}
