@TE-KarlKomierowski

So I've been going through documentation and it looks like I may be running into a "FIFO Overflow" issue: AS_ATTENTION_SUB_CODE_SIMPLE_FIFO_OVERFLOW

And the error information states:

Simple fifo between application and sdk became full. Extraction speed may be slower than Insertion. Coordinate task priority of application to avoid queue remain increaseing.

Also saw recommendations to increase task priority or increase the buffer size.

I'm a bit lost and am not sure where to go from here. Would really appreciate any guidance anyone can provide...

Thank you!

@cjb The two Settings parameters needed are "target" and "value", which you probably already have discovered. Remember, power consumption is over 30w when powered off when Network Standby is enabled. Heat might increase too! Sony have now removed the 1.5w from the website specs now. Hmmm....

My prediction is that 'Network Standby' for EU models will disappear with the next firmware update. I wish they would enable Wake On LAN (called "Remote Start" by Sony) for EU models instead because it uses very little power! The setting ("wolMode") can be enabled via the API on EU models, but the hardware does nothing.

Hi @TE-KarlKomierowski as you said I pressed the SPRESENSE a bit on the extension board and seems the SD card is now working. So the issue was the SPRESENSE was not connected properly on the extension board.

Thanks you very much for the help.

Thanks four your feedback, will relay it to the engineering team.

The more that ask the more I have to bargain with

Hi @david,

Thanks for the response!!

Actually it looks like this developer is saying that the ESP8266-01 won't work with Spresense so he had to use the AdaFruit Feather. I can confirm that I have been able to get my ESP8266-01 module working at one point with Spresense, but for some reason it has completely stopped working. I wonder if my module is damaged somehow even though I am able to connect my module using an adapter board and run simple commands like blinking the lights.

Hi @atw72

Could you try the following and see what the outcome is?

#include <SDHCI.h> #include <Audio.h> SDClass theSD; AudioClass *theAudio; File myFile; bool ErrEnd = false; /** @brief Audio attention callback When audio internal error occurc, this function will be called back. */ static void audio_attention_cb(const ErrorAttentionParam *atprm) { puts("Attention!"); switch (atprm->error_code) { case AS_ATTENTION_CODE_INFORMATION: case AS_ATTENTION_CODE_WARNING : ErrEnd = false; break; case AS_ATTENTION_CODE_ERROR : case AS_ATTENTION_CODE_FATAL : default: ErrEnd = true; } } /** @brief Setup recording of mp3 stream to file Select input device as microphone <br> Initialize filetype to stereo mp3 with 48 Kb/s sampling rate <br> Open "Sound.mp3" file in write mode */ static const int32_t recoding_frames = 400; static const int32_t recoding_size = recoding_frames * 288; /* 96kbps, 1152sample */ void setup() { theAudio = AudioClass::getInstance(); theAudio->begin(audio_attention_cb); puts("initialization Audio Library"); /* Select input device as microphone */ theAudio->setRecorderMode(AS_SETRECDR_STS_INPUTDEVICE_MIC, AS_MICGAIN_HOLD, 68, true); /* Initialize filetype to stereo mp3 with 48 Kb/s sampling rate Search for MP3 codec in "/mnt/sd0/BIN" directory */ theAudio->initRecorder(AS_CODECTYPE_MP3, "/mnt/sd0/BIN", AS_SAMPLINGRATE_48000, AS_CHANNEL_STEREO); puts("Init Recorder!"); /* Open file for data write on SD card */ myFile = theSD.open("sound.mp3", FILE_WRITE); /* Verify file open */ if (!myFile) { printf("File open error\n"); exit(1); } theAudio->startRecorder(); puts("Recording Start!"); } /** @brief Record given frame number */ void loop() { err_t err; /* recording end condition */ if (theAudio->getRecordingSize() > recoding_size) { theAudio->stopRecorder(); sleep(1); err = theAudio->readFrames(myFile); goto exitRecording; } /* Read frames to record in file */ err = theAudio->readFrames(myFile); if (err != AUDIOLIB_ECODE_OK) { printf("File End! =%d\n", err); theAudio->stopRecorder(); goto exitRecording; } if (ErrEnd) { printf("Error End\n"); theAudio->stopRecorder(); goto exitRecording; } /* This sleep is adjusted by the time to write the audio stream file.

Hi @JCPStevens ,

Ok, let's sort this out once for all.

I did the following on a Ubuntu machine to get this to work:

git clone --recursive git@github.com:TE-KarlKomierowski/hackster_projects.git

After that I opened Arduino IDE and from the Sketch menu I took Include library->Add .ZIP library
In the file browser I selected the folder in the git repo as follows:

~/hackster_projects/spresense-audio-scope/arduino-lib
I selected TFT folder and clicked OK

I then opened arduino-scope-ino in the Arduino IDE and pressed the button Verify to build the sketch.

This failed. It turns out that the TFT library defines a macro that is named swap and this is later being used in other libraries which confuses the build system.

The quickes way to get around this for me was to simply add the following on line 7 to the arduino-scope.ino sketch:

#undef swap

The undef part must be between the include <TFT> and include <Audio.h>

#include <TFT.h> /* Include TFT.h first, then Audio.h to avoid __SD_H__ being defined in the Audio.h. */ #undef swap #include <Audio.h>

After doing this I can build the sketch.
I have been using a Ubuntu PC with Arduino IDE version 1.8.9.

I have built for target Spresense.

Hope that this will work for you too.
If you run into problems, please past your errorlog into your post and I will try to help out.

Thanks for the link and advice @TE-KarlKomierowski . I just need to do a quick and dirty demo without burning the Spresense in the process. I won't use those batteries on real deployments because they can easily leak toxic fluids.

BR.
Carlos.

@CGM11 said in NNC:

@TE-KarlKomierowski Sorry Karl, I didn't see your answer. But as I told you, it is good for other people to know it as well, the NNC works pretty fine in a MacBook Pro using Parallels.

Regards and thank you.

Hi @CGM11

Ok, thank you for the information!

Probably I get an error message when I try the git command because the ZIP download already exists. I thougt that the library file wasn't installed.
But the next problem is that the example Sketch audio_scope already gives an error message by compiling it, and I don't have the knowledge to understand the code completely.
Until now I thougt that the Sketch wouldn't work because the required library wasn't available.
I have taken over the Sketch litterally from the Sony Spresense Sample Projects tutorials.
What is here going wrong?

Already thanks for the effort,
greets Marc.

@TE-KarlKomierowski
I enabled the DMA option as you suggested, but I did not notice any change to the severity of the flickering. I also checked ILI9340_SPI_MAXFREQUENCY and it was set to 40000000 just as your example.

I agree regarding the NX graphics + framebuffer usage. No sense in re-inventing the wheel. Now that I have discovered a "hook" into the framebuffer, the NX documentation might make a little more sense. I will revisit and research a bit more.

I will definitely keep this thread updated...I also think it is an important dev topic and worth digging into. Stay tuned!

Hi @JCPStevens

By default, when the mode is set to INPUT, the pin state is HIGH. If you want to change it to LOW, change the pin state to LOW.

You can use my example below:

int left=0; int right=0; void setup() { pinMode(4,INPUT); pinMode(6,INPUT); digitalWrite(4, LOW); digitalWrite(6, LOW); Serial.begin(115200); } void loop() { left=digitalRead(4); right=digitalRead(6); if (left==(HIGH)){ Serial.println("Left=High");} if (left==(LOW)){ Serial.println("Left=low");} if (right==(HIGH)){ Serial.println("Right=high");} if (right==(LOW)){ Serial.println("Right=low");} }

Thanks Karl! I will give it a try....

Thank you I managed to get the RAW format

Thanks for notifying us, we are looking in to the cause of this problem and how to fix it.

Hi @Ben-eaton

In the last code the ErrEnd will be set true when you get an error, if you instead of executing goto exitSketch just stop and restart the recording things shouldn't freeze. I have not verified this to 100% but I got this information from a college.

@Ben-eaton said in Recording at 192khz freezes:

if (ErrEnd)
{
printf("Error End\n");
theAudio->stopRecorder();
goto exitSketch;
}

I know that this issue have been discussed via email and our ambition is to post a conclusion in this thread once we have a final answer for you and the rest of the forum readers.
