系统基本结构:采集红外探测器的Raw信号,用SAA7121H显示,
配置如下:
{0x26,0x00},{0x27,0x00},{0x28,0x21},{0x29,0x1d},{0x3A,0x03},{0x5A,0x0c},
{0x5B,0x7d},{0x5c,0xaf},{0x5d,0x23},{0x5e,0x35},{0x5f,0x35},{0x60,0x00},
{0x61,0x06},{0x62,0x2F},{0x63,0xcb},{0x64,0x8a},{0x65,0x09},{0x66,0x2a},
{0x67,0x55},{0x68,0x56},{0x69,0x67},{0x6a,0x58},{0x6b,0x20},{0x6c,0x05},
{0x6d,0x20},{0x6e,0xa0},{0x6f,0x14},{0x70,0x80},{0x71,0xe8},{0x72,0x10},
{0x73,0x42},{0x74,0x03},{0x75,0x03},{0x76,0x05},{0x77,0x16},{0x78,0x04},
{0x79,0x16},{0x7a,0x18},{0x7b,0x38},{0x7c,0x40},{0x7d,0x00},{0x7e,0x00},
{0x7F,0x00}
这是我存在SDRAM的数据,然后导出在matlab中显示形成的。
这是我显示屏上的图像(绿),
不知是何原因?晶振是板子前端AD提供的,接的是SAA7121H的第4脚,27MHZ。 |
