网站每年续费费用,个人简历免费制作网站,导购网站怎么建立,有哪些建设网站公司1. 可以选择I2C1#xff0c;也可以选择I2C2#xff0c;或者同时选择#xff0c;同时运行 配置时钟信号 为节约空间#xff0c;选择这两个#xff0c;然后选择GENERATE CODE 二、HAL_I2C_Mem_Write I2C_HandleTypeDef *hi2c#xff1a;I2C设备句柄 uint16_t DevAddress也可以选择I2C2或者同时选择同时运行 配置时钟信号 为节约空间选择这两个然后选择GENERATE CODE 二、HAL_I2C_Mem_Write I2C_HandleTypeDef *hi2cI2C设备句柄 uint16_t DevAddress目标器件的地址七位地址必须左对齐 uint16_t MemAddress目标器件的目标寄存器地址 uint16_t MemAddSize目标器件内部寄存器地址数据长度 uint8_t *pData待写的数据首地址 uint16_t Size待写的数据长度 uint32_t Timeout超时时间 返回值 HAL_StatusTypeDef HAL 状态 OK busy ERROR TIMEOUT 向OLED写入命令的封装 void Oled_Write_Cmd(uint8_t dataCmd)
{HAL_I2C_Mem_Write(hi2c1,0x78,0x00,I2C_MEMADD_SIZE_8BIT,dataCmd,1,0xff);
} 向 OLED 写数据的封装最大的区别是目标器件的目标寄存器地址变成了0x40 void Oled_Write_Data(uint8_t dataData)
{
HAL_I2C_Mem_Write(hi2c1,0x78,0x40,I2C_MEMADD_SIZE_8BIT,dataData,1,0xff);} 三、初始化Oled官方手册上面有,清屏函数调入图片的亮点到数组显示函数。
初始化Oled:
void Oled_Init(void){
Oled_Write_Cmd(0xAE);//--display offOled_Write_Cmd(0x00);//---set low column addressOled_Write_Cmd(0x10);//---set high column addressOled_Write_Cmd(0x40);//--set start line address Oled_Write_Cmd(0xB0);//--set page addressOled_Write_Cmd(0x81); // contract controlOled_Write_Cmd(0xFF);//--128 Oled_Write_Cmd(0xA1);//set segment remap Oled_Write_Cmd(0xA6);//--normal / reverseOled_Write_Cmd(0xA8);//--set multiplex ratio(1 to 64)Oled_Write_Cmd(0x3F);//--1/32 dutyOled_Write_Cmd(0xC8);//Com scan directionOled_Write_Cmd(0xD3);//-set display offsetOled_Write_Cmd(0x00);//Oled_Write_Cmd(0xD5);//set osc divisionOled_Write_Cmd(0x80);//Oled_Write_Cmd(0xD8);//set area color mode offOled_Write_Cmd(0x05);//Oled_Write_Cmd(0xD9);//Set Pre-Charge PeriodOled_Write_Cmd(0xF1);//Oled_Write_Cmd(0xDA);//set com pin configuartionOled_Write_Cmd(0x12);//Oled_Write_Cmd(0xDB);//set VcomhOled_Write_Cmd(0x30);//Oled_Write_Cmd(0x8D);//set charge pump enableOled_Write_Cmd(0x14);//Oled_Write_Cmd(0xAF);//--turn on oled panel }
清屏函数
void Oled_Screen_Clear(void){char i,n;Oled_Write_Cmd (0x20); //set memory addressing modeOled_Write_Cmd (0x02); //page addressing modefor(i0;i8;i){Oled_Write_Cmd(0xb0i); //éè??ò3μ??·¨0~7?Oled_Write_Cmd(0x00); //éè????ê??????aáDμíμ??·Oled_Write_Cmd(0x10); //éè????ê??????aáD??μ??· for(n0;n128;n)Oled_Write_Data(0x00); }
}
设置图片的点阵,可以通过电脑画图软件画 通过取模软件生成数据将图片的亮点放到数组
