器件型号：TLV320AIC3105 主题中讨论的其他器件：TLV320AIC3104、
您好！
有一个文档《 TLV320AIC3104编程更加轻松 》、我将其用作参考。 它在本文档末尾列出了一个启动脚本。 我尝试参考这些内容以便让3105启动并运行。
我将从一个简单的示例开始... 我想、让我"为左右 DAC 加电"、即页0x00寄存器0x25 (37)。 我正在进行硬件复位(将 RESET 下拉至低电平、然后变为高电平)。 然后我将执行软件复位(写入复位寄存器)。
// hardware reset
pinMode(RESET_PIN,OUTPUT);
digitalWrite(RESET_PIN,HIGH);delay(50); //not reset
digitalWrite(RESET_PIN,LOW);delay(100); //reset
Serial.println("-----this should fail-----");
writeRegister(wires, dev, Page_00, 0x01, 0b10000000);
Serial.println("-----now turning it back on-----");
digitalWrite(RESET_PIN,HIGH);delay(50);//not reset
Serial.println("-----Hardware reset complete-----");
// reset to defaults
writeRegister(wires, dev, Page_00, 0x01, 0b10000000); // Reset Module | 0b00010001 | 0x11
writeRegister(wires, dev, Page_00, 0x01, 0b00000000); // Reset Module | 0b00010001 | 0x11
if (debugToSerialTLV320AIC3105) Serial.println("-- Software Reset Complete ---");
// wait for device to initialize
delay(50);
//TEST SIMPLE DAC ENABLE/DISABLE.
writeRegister(wires, dev, Page_00, 37, 0b1110000);delay(50); //
writeRegister(wires, dev, Page_00, 38, 0b00010100);delay(50); //
writeRegister(wires, dev, Page_00, 40, 0b11010101);delay(50); //
dumpAllRegisters(wires, dev);
但是、当我运行代码时、结果不会"粘住"、这是不是为了让 I2C 设置在写入时粘住、我首先必须做些什么？

初始化编解码器的基本步骤是什么？ 很抱歉这里的基本问题,我已经与这个做了几天,我正在寻找一些帮助,希望得到这个移动. 谢谢！
