我买了两次STA321MPL:第一次使用芯片上的标签:
“” “” 片上标签第2次:'' “” 不幸的是,所有STA321MPL从第二次(一周前)开始 使用我的电路板和我的固件。我可以通过I2C写入和读取寄存器,但没有输出信号:LRCKO,SDO12,SDO34,SDO56。 对于带有IC标签的STA321MPL:'' '',我在一年前的第一次购买,他们可以完美地使用我的电路板和我的固件。 你知道两个版本的STA321MPL有什么不同吗? 我该如何解决问题或如何购买 STA321MPL有标签'' ''。 谢谢! 以上来自于谷歌翻译 以下为原文 I bought STA321MPL 2 times: 1st times with the label on chip: '' '' 2nd times with the label on chip: '' '' Unfortunately, all STA321MPL from the 2nd times (a week ago) are working with my board and my firmware.I can write and read its register via I2C, but there is no output signal: LRCKO, SDO12, SDO34, SDO56. For STA321MPL with the label in IC : '' '', I bought in the first time a year ago , they can work perfectly with my board and my firmware. Do you know what is different between 2 versions of STA321MPL? how can I fix the issue or how I can buy STA321MPL witn the label '' ''. Thank you! |

谢谢你的回复,
XTI的时钟为12,288 Mhz CKOUT具有时钟> 3Mhz - >我的采样频率16Khz的配置是错误的 我用新的STA321MPL制作了5块板,都没有用。 我用2个板上的STA321MPL替换旧版(仅剩2个),两个都正常工作 我在ST板上更换了新的STA321MPL:STEVAL-MKI126V3。 ST板未与APWorkbench一起使用。 也许我错了,但我认为两个版本的STA321MPL没有区别。 以上来自于谷歌翻译 以下为原文 Thank for your reply, XTI has clock 12,288 Mhz CKOUT has clock > 3Mhz --> it is wrong with my configuration of sampling frequency 16Khz I made 5 boards with new STA321MPL, all were not working. I replaced STA321MPL on 2 boards with old ones (remain only 2pcs), both are working I replaced new STA321MPL on ST board: STEVAL-MKI126V3. The ST board was not working with APWorkbench. Maybe I am wrong, but I don't think there are no difference between 2 versions of STA321MPL. |

嗨,
请获取我的APC文件。 你来自ST吗?如果是,您可以进行测试:用新的STA321MPL替换主板STEVAL-MKI126V3上的STA321MPL:'''',看看它是否正常工作? 如果你能这样做,我真的很感激。 以上来自于谷歌翻译 以下为原文 Hi, Please get my APC file. Are you from ST? If yes, could you do the testing: Replace the STA321MPL on the board STEVAL-MKI126V3 by the new STA321MPL: '''', and see whether it is working or not? If you can do so, I really appreciate it. |

嗨,潘,
根据您的APC文件,它与ST默认设置类似,对吧? 请帮助检查电路板上的麦克风时钟,有一些跳线可以从clkout(1,1 / 2,1 / 4)中选择不同的分频比。 如果麦克风时钟为3.072Mhz / 4,则数字麦克风可能无法正常工作。 谢谢 YT 以上来自于谷歌翻译 以下为原文 hi Phan, according to your APC file, it's similar with ST default setting, right ? please help to check the microphone clock in your board , there are some jumpers to select different divide ratio from clkout ( 1,1/2,1/4) . if the microphone clock was 3.072Mhz /4 , digital microphone may not work properly . Thanks YT |

嗨云涛,
它被配置为不在板上划分时钟。我多次使用过这个工具和这个板子。一直都很好。除非我将STA321MPL更改为新的。 在这种情况下,仍然有麦克风的时钟输入和麦克风的数据输出。但SDO12,SDO34,SDO56,LRCKO上没有信号。使用新STA321MPL的麦克风阵列板的行为是一样的。 旧的STA321MPL始终与STEVAL-MKI126V3以及我的麦克风阵列板配合使用。 我的项目陷入了这个问题。我不知道如何解决它。我花了几个月的时间将固件写入STA321MPL,现在它不适用于新的IC。 以上来自于谷歌翻译 以下为原文 Hi Yun Tao, It was configured not to divide clock on the board. I have used this tool and this board many times. All the times worked well. Except when I changed the STA321MPL to new one. In this case, still having clock input to microphone and data output from microphone. but there is no signal on SDO12, SDO34, SDO56, LRCKO. The behavior is the same with my mic-array board with new STA321MPL. The old STA321MPL is always working with STEVAL-MKI126V3 as well as my mic-array board . My project is stuck in this issue. I don't have any idea how to solve it. It took me months to write firmware to STA321MPL and now It is not working for new ICs. |

嗨,潘,
请分享您的APWorkbench偏好,您是否在启动时应用了重置? 谢谢 YT 以上来自于谷歌翻译 以下为原文 hi Phan, please share your APWorkbench preferences , did you apply reset during start up ? Thanks YT |

嗨云涛,
我使用的是APWorkbench 2.1版。 我没有在开始时应用任何东西。我习惯了APWorkbench,我可以用旧的STA321MPL让它运行正常一千次。 顺便说一句,我刚刚发现了一个我的旧芯片STA321MPL(2012年第37周),我安装到我的主板上,它正在工作。 你可以像我提到的那样进行测试:用MKI126V3板上的代码“''替换STA321MPL,让我们看看它是否能正常工作? 谢谢! 以上来自于谷歌翻译 以下为原文 Hi Yun Tao, I am using APWorkbench version 2.1. I did not apply anything during start. I was used to APWorkbench, I could make it run correctly thousand times with old STA321MPL. BTW, I just found one more my old chip STA321MPL (2012 week 37) and I installed to my board and it is working. Can you do a test as I mentioned: replace the STA321MPL with the code '''' on MKI126V3 board and let's see whether it would work correctly any more? Thank you! |

嗨,潘,
根据你提到的症状,最可能的问题是初始化失败,然后澄清它,请仔细检查以下项目: 1)点击APW左侧的复位和初始化按钮; 2)麦克风演示套件的负载设置 3)按范围验证CLKOUT频率 如果可能,请使用APWorkbench中的专家模式转储寄存器设置。 谢谢 YT 以上来自于谷歌翻译 以下为原文 hi Phan , according to the symptom you mentioned , the most possible issue was initialization failed , then to clarify it , please double check below items : 1) click reset and initialization button in APW left side ; 2) load setting for microphone demo kit 3) verify CLKOUT frequency by scope and if possible , please use expert mode in APWorkbench to dump register setting . thanks YT |

嗨芸涛,
我按照你的指示,但它仍然无法正常工作。 APWorkbench上仍然没有音频信号。 随着STA321MPL于2012年第37周生产,我的主板可以运行: https://www.youtube.com/watch?v=69U0Q0kh8qQ 但是哪个STA321MPL在2015年第32周生产,我的主板无法运行。 谢谢! 以上来自于谷歌翻译 以下为原文 hi Yun Tao, I followed your instructions , however it is still not working. Still there is no audio signal on APWorkbench. With STA321MPL produded on 2012 week 37th, my board can run: https://www.youtube.com/watch?v=69U0Q0kh8qQ But which STA321MPL produced on 2015 week 32nd, my board could not run. Thank you! |

嗨,潘,
请检查右侧底部连接器中的I2S输出信号,以确认在建议的初始化步骤实施后STA321MPL的时钟和数据输出状态。 您还可以使用示波器检查耳机插孔上的耳机输出信号。 如果电路板上仍然没有模拟音频输出和I2S信号输出,您最好联系当地的dist或ST办公室寻求支持。 谢谢 YT 以上来自于谷歌翻译 以下为原文 hi Phan , Please check I2S output signals in right bottom side connector to confirm status of clock and data output from STA321MPL after recommended initialization step had been implemented . and you also can use scope to check headphone output signal at the headphone jack. if there are still no analog audio output and I2S signal output in the board , you'd better to contact with your local dist or ST office for support. Thanks YT |
