你(们)好
我现在正在诊断视频输出的哪个部分有问题。 SER:941 DES:948现在我想从948输出模式。 我的配置如下:
WriteOfI2c_Byte(UB948,0x49,0x80);//set mode_SEL0
WriteOfI2c_Byte (UB948,0x1D0x05);
WriteOfI2c_Byte (UB948,0x1E,0x55);
WriteOfI2c_Byte(UB948,0x66,0x03); //启用PGCDC1
WriteOfI2c_Byte (UB948,0x67,0x03); //66.6M pclock
//H V 1920*480
WriteOfI2c_Byte (UB948,0x66,0x07);
WriteOfI2c_Byte(UB948,0x67,0x80);
WriteOfI2c_Byte (UB948,0x66,0x08);
WriteOfI2c_Byte (UB948,0x67,0x07);
WriteOfI2c_Byte (UB948,0x66,0x09);
WriteOfI2c_Byte (UB948,0x67,0x1E);
// H V共计 1938年*570
WriteOfI2c_Byte (UB948,0x66,0x04);
WriteOfI2c_Byte (UB948,0x67,0x92);
WriteOfI2c_Byte (UB948,0x66,0x05);
WriteOfI2c_Byte (UB948,0x67,0xA7);
WriteOfI2c_Byte (UB948,0x66,0x06);
WriteOfI2c_Byte(UB948,0x67,0x23);
//HBP:14.
WriteOfI2c_Byte (UB948,0x66,0x0C);
WriteOfI2c_Byte (UB948,0x67,0x0E);
//VBP: 6.
WriteOfI2c_Byte (UB948,0x66,0x0D);
WriteOfI2c_Byte(UB948,0x67,0x06);
//H同步13.
WriteOfI2c_Byte (UB948,0x66,0x0A);
WriteOfI2c_Byte (UB948,0x67,0x0D);
//V同步6.
WriteOfI2c_Byte (UB948,0x66,0x0B);
WriteOfI2c_Byte(UB948,0x67,0x06);
WriteOfI2c_Byte (UB948,0x66,0x0E);//启用PBSC
WriteOfI2c_Byte (UB948,0x67,0x03); /set negive
WriteOfI2c_Byte (UB948,0x65,0x03); //启用24位和内部时钟
WriteOfI2c_Byte(UB948,0x64,0x11); //启用模式生成器
我写入了941的0x01寄存器WriteOfI2c_Byte(UB941,0x01,0x08);以关闭941的DSI。 确保不要影响948输出模式。
但是,连接至mipi信号芯片的后一个LVDS无法识别LVDS信号,两个信号检测到的时钟为1.6468万,应该为3.23万。
有什么问题? 是否有任何其它寄存器未配置?或者我的想法错误?
谢谢
