0.96寸，串口OLED屏，分辨率12864，就是好小啊，控制器SSD1306。 void OLED_WrDat(unsigned char dat)//写数据 { unsigned char i; OLED_DC_Set(); for(i=0;i<8;i++) { if((dat << i) & 0x80) { OLED_SDA_Set(); } else OLED_SDA_Clr(); OLED_SCL_Clr(); OLED_SCL_Set(); } } void OLED_WrCmd(unsigned char cmd)//写命令 { unsigned char i; OLED_DC_Clr(); for(i=0;i<8;i++) //发送一个八位数据 { if((cmd << i) & 0x80) { OLED_SDA_Set(); } else { OLED_SDA_Clr(); } OLED_SCL_Clr(); OLED_SCL_Set(); } } void OLED_SetPos(unsigned char x, unsigned char y)//设置起始点坐标 { OLED_WrCmd(0xb0 + y); OLED_WrCmd(((x&0xf0)>>4)|0x10); OLED_WrCmd((x&0x0f)|0x01); } void OLED_Fill(unsigned char bmp_dat)//全屏填充 { unsigned char y,x; for(y=0;y<8;y++) { OLED_WrCmd(0xb0+y); OLED_WrCmd(0x01); OLED_WrCmd(0x10); for(x=0;x126) { x=0;y++; } OLED_SetPos(x,y); for(i=0;i<6;i++) { OLED_WrDat(F6x8[c]); } x+=6; j++; } } void OLED_8x16Str(unsigned char x, unsigned char y, unsigned char ch[]) { unsigned char c=0,i=0,j=0; while (ch[j]!='\0') { c =ch[j]-32; if(x>120) { x=0;y++; } OLED_SetPos(x,y); for(i=0;i<8;i++) { OLED_WrDat(F8X16[c*16+i]); } OLED_SetPos(x,y+1); for(i=0;i<8;i++) { OLED_WrDat(F8X16[c*16+i+8]); } x+=8; j++; } } void OLED_16x16CN(unsigned char x, unsigned char y, unsigned char N) { unsigned char wm=0; unsigned int adder=32*N; OLED_SetPos(x , y); for(wm = 0;wm < 16;wm++) { OLED_WrDat(F16x16[adder]); adder += 1; } OLED_SetPos(x,y + 1); for(wm = 0;wm < 16;wm++) { OLED_WrDat(F16x16[adder]); adder += 1; } } 本帖最后由 gxliu08 于 2015-1-19 21:02 编辑
