硬件连接是上图方式，希望能给个驱动代码，ADS1248，ADS1247的code都可以
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[i]= Receive_Data_SPI(); } Clear_ADS1247_Chip_Enable();
目前寄存器能读能写，但是读取数据，一直读出来为0，求解
Set_ADS1247_Chip_Enable(1); Send_Data_SPI(0x04); Send_Data_SPI(0x04); Clear_ADS1247_Chip_Enable(1); __delay_cycles(500); Set_ADS1247_Chip_Enable(1); while(DOUT1); Send_Data_SPI(0x12); bufferIN[0] = Receive_Data_SPI(1); bufferIN[1] = Receive_Data_SPI(1); bufferIN[2] = Receive_Data_SPI(1);
