AD7147只出STAGE0的数值，其他stage的寄存器输出均为0

3785 AD7147

问答对人有帮助，内容完整，我也想知道答案 0 利用附上的代码，实现与AD7147通信成功，但在AD7147的conversion sequence里面配置了12个stage运行，然后出来的结果只有stage0是有值的，从其他stage寄存器读出的值均为0。针对AD7147芯片手册重新配置了一遍AD7147，结果还是依旧，很迷惑。求高手解决！配置描述：寄存器2配置： stage0 --CIN0(+) stage1 --CIN1(+) stage2 --CIN0(+) stage3 --CIN3(+) stage4 --CIN4(+) stage5 --CIN5(+) stage6 --CIN6(+) stage7 --CIN7(+) stage8 --CIN8(+) stage9 --CIN9(+) stage10 --CIN10(+) stage11 --CIN11(+) 寄存器1配置寄存器高位地址低位地址高位数据低位数据 SETUP_7148_a(0x00 ,0x00 ， 0x01, 0x12);
