关于通过ADS1298ECG Front-End Performance Demonstration Kit的J3接口去控制ADS1298的问题

Other Parts Discussed in Thread: ADS1298, TMS320C5515

您好

    我现在使用的是TI的ADS1298ECG Front-End Performance Demonstration Kit套件。我想先通过该板子上的J3扩展口对ADS1298进行控制,但是在连接了电源线和和cs、SPI进出和时钟、start等线以后。在 ADS1298_SpiSend_CMD_One(SDATAC);                         // 发送停止命令
                                                                             ADS1298_SpiRecive_Data(0x20+Addr_ID,1,d);                // 读ADS1298 ID号
                                                                              if(d[0]==0x92)               

以这条语句所读的的ID号并不是0x92. 我用的MSP430的SPI口,无论设置成哪种时钟模式都不正确。debug时通过对TXBUF的查看,其输出是对的。请问这个问题可能会出在哪呢。
