请问谁能给个驱动代码吗？

可以看看这里：http://paapps.tucs.design.ti.com/doku.php?id=parts:ads:ads1247:evm:start
另外建议你根据datasheet的时序自己写一遍，然后看看能不能正常通信，这样对自己学习有很大帮助

底层通讯已经写好，就是有点难理解它的写寄存器的方式，另外这个网页好像无法访问

我给你附上了：

通讯是可以通讯了，但是电流却没有输出  
Set_ADS1247_Chip_Enable();
Send_Data_SPI(0x40);
Send_Data_SPI(0x0e);
Send_Data_SPI(0x2e);//MUX0 00101110
Send_Data_SPI(0);//VBIAS
Send_Data_SPI(0x05);//MUX1 00000101
Send_Data_SPI(0x0f);//SYS0 00001111
Send_Data_SPI(0);//OFC0
Send_Data_SPI(0);//OFC1
Send_Data_SPI(0);//OFC2
Send_Data_SPI(0);//FSC0
Send_Data_SPI(0);//FSC1
Send_Data_SPI(0);//FSC2
Send_Data_SPI(0x0f);//IDAC0 00001111
Send_Data_SPI(0x47);//IDAC1 0x47
Send_Data_SPI(0);//GPIOCFG 0
Send_Data_SPI(0xff);//GPIODIR ff
Send_Data_SPI(0);//GPIODAT 00
Clear_ADS1247_Chip_Enable();


Set_ADS1247_Chip_Enable();
Send_Data_SPI(0x20);
Send_Data_SPI(0x0e);
for(uint8_t i=0; i<15; i++)
[
tab= Receive_Data_SPI();
]
Clear_ADS1247_Chip_Enable();
