1:配置寄存器读写正确
2:1、2通道配置为标准导联配置文件如下:
void Ads1298Setting(void)
{
Ads1298RegWrite(EXT_GPIO,0x50);
Ads1298RegWrite(CONFIG1,0x86);
Ads1298RegWrite(CONFIG2,0x00);
Ads1298RegWrite(CONFIG3,0xDC); //DC
Ads1298RegWrite(LOFF,0x03);
{
Ads1298RegWrite(EXT_GPIO,0x50);
Ads1298RegWrite(CONFIG1,0x86);
Ads1298RegWrite(CONFIG2,0x00);
Ads1298RegWrite(CONFIG3,0xDC); //DC
Ads1298RegWrite(LOFF,0x03);
Ads1298RegWrite(RLD_SENSP,0x00);
Ads1298RegWrite(RLD_SENSN,0xfc);
Ads1298RegWrite(LOFF_SENSP,0xff);
Ads1298RegWrite(LOFF_SENSN,0x00);
Ads1298RegWrite(LOFF_FLIP,0x00);
Ads1298RegWrite(RLD_SENSN,0xfc);
Ads1298RegWrite(LOFF_SENSP,0xff);
Ads1298RegWrite(LOFF_SENSN,0x00);
Ads1298RegWrite(LOFF_FLIP,0x00);
Ads1298RegWrite(CH1SET,0x00);
Ads1298RegWrite(CH2SET,0x00);
Ads1298RegWrite(CH3SET,0x00);
Ads1298RegWrite(CH4SET,0x00);
Ads1298RegWrite(CH5SET,0x00);
Ads1298RegWrite(CH6SET,0x00);
Ads1298RegWrite(CH7SET,0x00);
Ads1298RegWrite(CH8SET,0x00);
Ads1298RegWrite(CH2SET,0x00);
Ads1298RegWrite(CH3SET,0x00);
Ads1298RegWrite(CH4SET,0x00);
Ads1298RegWrite(CH5SET,0x00);
Ads1298RegWrite(CH6SET,0x00);
Ads1298RegWrite(CH7SET,0x00);
Ads1298RegWrite(CH8SET,0x00);
Ads1298RegWrite(PACE,0x00);
Ads1298RegWrite(RESP,0x00);
Ads1298RegWrite(CONFIG4,0x02);
Ads1298RegWrite(WCT1,0x0B);
Ads1298RegWrite(WCT2,0xC2);
}
Ads1298RegWrite(RESP,0x00);
Ads1298RegWrite(CONFIG4,0x02);
Ads1298RegWrite(WCT1,0x0B);
Ads1298RegWrite(WCT2,0xC2);
}
3:采样电路原理如下基本按开发板上的处理(已检查好多次)
4:用手触摸导联采样数据有变化,
5:采样标准发生器产生标 I 导的波形的数据呈方波阶梯的变化
6:事情比较急,高手请指教
Jack Li:
如你能正常读写内部的寄存器,说明你的读写时序可以正常工作,那主要检查你前面模拟部分了。建议把原理图贴上来,大家帮你看看。
