ADV7180BCPZ刷如下参数后,AIN1插上标清CVBS_PAL模拟摄像头, 用示波器测量这些BT656管脚(Pin11.LLC , Pin5.P7 pin6.p6pin7.p5 进针品红8.p4单线9.p3Pin10.P2 Pin5.P2 Pin16.P1 Pin17.P0),都没有任何信号.
注:电路直接用官方adv7180参考电路, Pin31,RESET/ 和Pin18.PWRDWN/已经是3.3V 问题 1: 配置参数是否正确? 2. bt656输出管脚PCLK_LLC输出27mHZ信号需要什么条件? Pin13.xtal启振条件有哪些?不配置任何参数上电用示波器能否测量到28.6Mhz? 3. 配置参数表在官方哪个页面下载?或用什么配置工具可以产生呢? 附初始化参数: 0x00,0x00, 0x01,0xc8, 0x02,0x04, 0x03,0x00, 0x04,0x45, 005,0x00, 006,0x02, 0x07,0x7F,0x7F, 0x08,0x80, 0x0A,0x00, 0x0B,0x00, 0x0C,0x36, 0x0D,0x7C,0x7C, 0x0E,0x00, 0x0F,0x00, 013,0x00, 014,0x12, 0x15,0x00, 0x16,0x00, 017,0x01, 018,0x93, 0F1, 0x19, 0x1A,0x00, 0x1B,0x00, 0x1C,0x00, 0x1D,0x40, 0x1E, 0x00, 0x1F,0x00, 0x20,0x00, 0x21,0x00, 0x22,0x00, 0x23,0xC0, 024,0x00, 0x25,0x00, 026,0x00, 0x27,0x58, 0x28,0x00, 0x29,0x00, 0x2A,0x00, 0x2B, 0xE1, 0x2C, 0xAE, 0x2D,0xF4, 0x2E, 0x00, 0x2F,0xF0,0xF0, 0x30,0x00, 031,0x12, 0x32,0x41, 0x33,0x84, 0x34,0x00, 0x35,0x02, 0x36,0x00, 0x37,0x01, 0x38,0x80, 0x39,0xC0, 0x3A,0x10, 0x3B,0x05, 0x3C,0x58, 0x3D,0xB2, 0x3E, 0x64, 0x3F,0xE4, 0x40,0x90, 0x41,0x01, 0x42,0x7E, 0x43, 0xA4, 0x44,0xFF,0xFF,0x44,0xFF,0xFF,0x44,0xFF,0x44,0xFF,0xFF,0xFF,0x44,0x44,0xFF,0xFF, 0x45, 0xB6, 时间轴: 0x45, 0xB6, 时间轴: 0xB6, 时间轴: 0x45, 0xB6, 时间轴: 0xB6, 时间轴: 0xB6, 时间轴: 0xB6, 时间轴: 0xB6, 时间轴: 0x46,0x12, 0x48,0x00, 0x49,0x00, 0x4A,0x00, 0x4B,0x00, 0x4C,0x00, 0x4D,0xEF, 0x4E,0x08, 0x4F,0x08, 0x50,0x08, 0x51,0x24, 0x52,0x0B, 0x53,0x4E, 0x54,0x80, 0x55,0x00, 0x56,0x10, 0x57,0x00, 0x58,0x00, 0x59,0x00, 0x5A,0x00, 0x5B,0x00, 0x5C,0x00, 0x5D,0x00, 0x5E,0x00, 0x5F,0x00, 0x60,0x00, 0x61,0x00, 0x62,0x20, 0x63,0x00, 0x64,0x00, 065,0x00, 0x66,0x00, 0x67,0x03, 0x68,0x01, 0x69,0x00, 0x6A,0x00, 0x6B,0xC0, 0x6C,0x00, 0x6D,0x00, 0x6E,0x00, 0x6F,0x00, 0x70,0x00, 0x71,0x00, 0x72,0x00, 0x73,0x10, 0x74,0x04, 0x75,0x01, 0x76,0x00, 0x77,0x3F, 0x78,0xFF, 0x79,0xFF, 0x7A,0xFF, 0x7B,0x1E, 0x7C, 0xC0, 0xC0, 0x7D,0x00, 0x7E,0x00, 0x7F,0x00, 0x80,0x00, 0x81,0xC0,0xC0, 0x82,0x04, 0x83,0x00, 0x84,0x0C, 0x85,0x02, 0x86,0x03, 0x87,0x63, 0x88,0x5A, 0x89,0x08, 0x8A,0x10, 0x8B,0x00, 0x8C,0x40, 0x8D,0x00, 0x8E,0x40, 0x8F,0x00, 0x90,0x00, 0x91,0x50, 0x92,0x00, 0x93,0x00, 0x94,0x00, 0x95,0x00, 096,0x00,0x00, 0x97,0xF0,0xF0, 0x98,0x00, 0x99,0x00, 0x9A,0x00, 0x9B,0x00, 0x9C,0x00, 0x9D,0x00, 0x9E,0x00, 0x9F,0x00, 0A0,0x00,0x00, 0xA1,0x00, 0A2,0x00, 0xA3,0x00, 0xA4,0x00, 0A5,0x00, 0A6,0x00, 0A7,0x00, 0A8,0x00, 0A9,0x00, 0AA,0x00, 0xAB,0x00,0x00, 0xAC,0x00,0x00, 0x00,0x00,0xAD, 0AE,0x60, 0xAF,0x00, 0xB0,0x00, 0xB1, 0x60, 0xB2, 0x1C, 0xB3,0x54, 0xB4,0x00, 0B5,0x00, 0B6,0x00, 0B7,0x13, 0B8,0x03, 0B9,0x33, 0xBF,0x02, 0xC0, 0x00, 0xC1,0x00, 0xC2, 0x00, 0xC3,0x00, 0xC4, 0x00, 0xC5, 0x81, 0C6,0x00, 0xC7,0x00, 0xC8, 0x00, 0C9,0x04, 0xCC,0x69, 0X,0x00,0x00, 0xCE,0x01, 0xCFF,0xB4, 0xD0,0x00, 0xD1, 0x10, 0D2,0xFF, 0D3,0xFF, 0xD4, 0x7F, 0D5,0x7F, 0D6, 0x3E, 0xD7,0x08, 0D8,0x3C, 0D9,0x08, 0xDA,0x3C, 0xDB, 0x9B, 0x9B, 0xDC,0xAC,0xAC, 0xDD, 0x4C, 10x4C, 10xDD, 0x4C, 0xDE,0x00, 0xDF,0x00, 0E0,0x14, 0E1,0x80, 0E2,0x80, 0E3, 0x80, 0E3, 0x80, 0E4,0x80,0x4,0x80, 0E5,0x25, 0E6,0x44, 0E7,0x63, 0E8,0x65, 0E9,0x14, 0xEA,0x63, 0xEB,0x55, 0xEC,0x55,0x55, 0xEE,0x00, 0xEF,0x4A, 0F0,0x44, 0F1,0x0C, 0F2, 0x32, 0F2, 0x32, 0F3, 0x00, 0F3, 0x00, 0F4,0x3F, 0F5, 0xE0, 0xE0, 0xF5, 0xE0, 0xF5, 0xEE0, 0xFF5, 0xEE0, 0xFFF5, 0xE0, 0xE0, 0xFFF5, 0xE0, 0xE0, 0xFF5, 0xE0, 0xE0, 0xE0, 0xF5, 0xE0, 0xE0, 0xE0, 0F5, 0xE0, 0xE0, 0xE0, 0xE0 0F6,0x69, 0F7,0x10, 0F8,0x00, 0F9,0x03, 0FA,0FA,0FA, 0FB,0x40, |
