• RE: DM0 and DM1 after reset in ADAU1450

    I haven't used SigmaStudio in a while, so I can't tell you what those compiler options do. My suggestion would be to just test them.

    Should it be needed, here's a variant of my program that also clears PM (except for the program itself obviously…

  • RE: Are writes with IPAT in ADAU1450 done at the end of a sample?

    Hello Reini,

    The IPAT table writes are exactly the same as safeload writes. They are done at the end of the regular code before the end of the frame. 

    I do want to add that in this processor you can write the gains without safeload or the IPAT table without…

  • RE: Serial Port Clock Domains in ADAU1450

    Just found this post after several days of searching. Had been pulling my hair out over this...

    Seeing the exact bug described on a board I designed. I am using port 0 as output, with LRCLK and BCLK both as master. I set port1 to slave from clk domain…

  • ADAU1450问题

    ADI的专家你们好,

    我在做ADAU1450的案子,发现这个跟1701设置有很大区别,现在主要碰到几个问题,ADC音量不能工作,ADC调节EQ也不行,还有ADAU1450不能用效果REVERB,显示DM1超了,能不能把REVERB设置在DM1,其它的都设置在DM0?另外还要做一个信号灯,用1450的IO口输出,设置灵敏度,比如检测到-60dB以上信号IO输出高,用于点亮LED,能给我个设置好的图吗?不胜感激!

    盼回复!

  • ADAU1450 multipurpose ports MP0/1/2/3/6/7 LED drive?

    Hello all,

    The datasheet of the ADAU1450 states that digital output ports cannot be used to drive a LED (page 8: $Electrical Characteristics, Digital Input/Output). Nothing is said explicit about the multipurpose pins. Does anyone know if the outputs…

  • ADAU1450 Volume Control

    I did a volume control test in the ADAU1450 and found no way to control the volume output (only no output and 3dB 2 results)

  • Popping Noises with the ADAU1450

    In my project I used the ADAU1450 to self-boot. I‘m having trouble with popping noise when I switched EQ.

    I have used DC-BLOCKING in my design. I also tried to mute before switching data, but these effects are not ideal.

    I would be very grateful…

  • ADAU1450 通过AUX ADC 检测电压值,如何使用 ReadBack 模块读取,他们的对应关系是怎样的

    各位老师好:

                  ADAU1450  通过AUX ADC 检测电压值,如何使用 ReadBack 模块读取,他们的对应关系是怎样的。

    比如,AUX ADC 脚1Vdc,对应的ReadBack  (8.24 格式或32.0格式)是多少?

    谢谢!

  • 一些ADAU1450问题

    我是新手,我有一个单独ADAU1450,没有MCU。

    ~但我发现我没法把程序烧录进去(SPI连接,在线编译时SigmaStudio MODE为红灯),最终我需要让测试版自启动

    ~还有如何修改为使用I2C?

    ~USBI连接MISO、SCLK、SS、GND?

    非常感谢!

  • ADAU1450 EQ切換爆音

    大家好

    我有一個自啓動ADAU1450,在做EQ切換的時候低音會出現’pop‘爆音

    我有在輸入添加DC-BOCLKING模塊,也試過在切換前做MUTE處理,結果都不理想

    感謝大家!
