ads1118模拟spi驱动问题

ads1118驱动，模拟spi，相关代码如下

unsigned int spi_sendRecvWord(unsigned int c){unsigned int data = 0;unsigned int shift = 0x8000;int i = 0;//while(!(ADS1118_DO_X))ADS1118_SCK_0;delay_us(120);for ( i = 0; i < 16; i++){if (c & shift){ADS1118_DI_1;}else{ADS1118_DI_0;}if(ADS1118_DO_X)data|=shift;ADS1118_SCK_1;delay_us(60);//if(ADS1118_DO_X)//data|=shift;ADS1118_SCK_0;delay_us(60);(shift) >>= 1;}

return data;}

float ADS1118_V(void){unsigned int adc=0;unsigned int Config_Register;float value=0;Config_Register =0x8393;ADS1118_CS_0;while((ADS1118_DO_X)){ADS1118_SCK_1;delay_us(60);ADS1118_SCK_0;delay_us(60);}delay_us(100);adc = spi_sendRecvWord(Config_Register);spi_sendRecvWord(0x0000);/* adc = spi_sendRecvWord(Config_Register);value=adc;return value;}

具体问题是无论我怎么改变写入控制字以及测量输入量，dout返回的都是如下错误波形，大家看看是什麽情况

图一：黄sclk，蓝dout

图二黄sclk，蓝din

图三，黄dout，蓝din

自己顶

没人再顶，不能沉了

我也刚玩了ADS1118

求份程序，看的我好头大...
