• aducm320和aducm320烧写问题

    最近项目上使用了一个ADUCM320芯片,烧写正常,但是最近采购芯片的时候采购成ADUCM320I,发现程序烧写不进去,但是看手册只有下载接口那块有区别,一个是mdio,一个是i2c,但是我下载的时候用的都是SW接口,按理说不应该出现烧写不进去的问题。现在发现ADUCM320的FLASH地址0x407e8读取出来的信息和ADUCM320I的不一样是,是不是ADUCM320I,我买到假芯片了。

    读取出来的数据截图如下:

  • ADuCM320 footprint

    Hi,

    In the ADuCM320 EVB schematics, I've found several not-connected balls e.g. H7, H5 ea. (see below)

    In the ADuCM320 datasheet, at the footprint description section, all these not-connected balls don't exist at all!

    E.g. ball H7 is not…

  • ADuCM320 DMA to DAC

    Hi,

    I am trying to use the DMA in ADuCM320 to generate a sin wave using one of the internal VDACs(or, alternatively an external SPI DAC). I want to use the DMA to write the waveform samples into the DAC in order to reduce the processor overhead and I…

  • ADuCM320 internal 2.5V reference

    Hello All,

     

    My costumer is asking me ADuCM320 internal 2.5V reference load current. The datasheet is stated 1.2mA, but looks like 2.0mA at the user guide.

    Could you let me know which value should we follow?  Are those under the same setup conditions…
