DAC8760: DAC8760在电流输出时如何禁用VOUT

您好，

将 Configuration寄存器的[10:7]位配置为0 ，Control寄存器的 RANGE bits配置输出范围，您是这样配置的吗

是的，下面是我初始化的程序；

int main(void)
{
init_readConfig();
system_init();
//DAC8760_Setup((DAC8760_RANGE_0V_10V + DAC8760_OUTEN), 0, 0, 0);
//DAC8760_SetOutValue(0x0);
SysCtlDelay(10000);
switch (DA_Setup_user[1])
{
case 0:// -10～+10V
DAC8760_Setup((DAC8760_RANGE_M10V_P10V + DAC8760_OUTEN), 0, 0, 0);
DAC8760_SetOutValue(32767);// Set DAC8760 output value to 0V
break;
case 1:// 0～10V
DAC8760_Setup((DAC8760_RANGE_0V_10V + DAC8760_OUTEN), 0, 0, 0);
DAC8760_SetOutValue(0); // Set DAC8760 output value to 0V
break;
case 2:// 0～5V
DAC8760_Setup((DAC8760_RANGE_0V_5V + DAC8760_OUTEN), 0, 0, 0);
DAC8760_SetOutValue(0); // Set DAC8760 output value to 0V
break;
case 3:// 0～20mA
DAC8760_Setup((DAC8760_RANGE_0MA_20MA + DAC8760_OUTEN), 0, 0, 0);
DAC8760_SetOutValue(0); // Set DAC8760 output value to 0V
break;
case 4:// -5～+5V
DAC8760_Setup((DAC8760_RANGE_M5V_P5V + DAC8760_OUTEN), 0, 0, 0);
DAC8760_SetOutValue(32767);// Set DAC8760 output value to 0V
break;
case 5:// 4～20mA
DAC8760_Setup((DAC8760_RANGE_4MA_20MA + DAC8760_OUTEN), 0, 0, 0);
DAC8760_SetOutValue(0); // Set DAC8760 output value to 0V
break;
default:
DAC8760_Setup((DAC8760_RANGE_M10V_P10V + DAC8760_OUTEN), 0, 0, 0);
DAC8760_SetOutValue(32767);// Set DAC8760 output value to 0V
break;
}

}

void DAC8760_Setup (uint16_t controlReg, uint16_t configurationReg, uint16_t gainCalReg, uint16_t zeroCalReg)
{
DAC8760_SPISetupMaster();
DAC8760_Reset();
DAC8760_Nop();
DAC8760_WriteReg (controlReg, DAC8760_WRITE_CONTROL_REGISTER);
DAC8760_WriteReg (configurationReg, DAC8760_WRITE_CONFIGURATION_REGISTER);
DAC8760_WriteReg (gainCalReg, DAC8760_WRITE_GAIN_CALIBRATION_REGISTER);
DAC8760_WriteReg (zeroCalReg, DAC8760_WRITE_ZERO_CALIBRATION_REGISTER);

}

抱歉，我这里无法验证您的程序，您可以把您配置的寄存器值读出来告诉我吗?我看一下Configuration和Control寄存器您是写入的是什么
