Hi,

This is a known issue. I have found a temporary solution for now. Unfortunately, this requires that you build the Spresense Arduino package again. You can use this: https://github.com/sonydevworld/spresense-arduino-compatible

Currently, when an error is detected, the Audio module stops working. However, this can be changed and when FIFO OVERFLOW is detected, samples can be dropped instead.

As a result, the application does not finish recording, but on the other hand does not guarantee that all samples will be saved.

Solution:

• Find function bool AudioRecorderSink::write(const AudioRecSinkData_s &param) in the file sdk/modules/audio/objects/media_recorder/audio_recorder_sink.cpp

• Comment line number 84.

• Return true instead of false on line number 85.

After the changes, the function should look like this:

bool AudioRecorderSink::write(const AudioRecSinkData_s &param)
{
  if (param.byte_size > 0) {
    if (CMN_SimpleFifoGetVacantSize(static_cast<CMN_SimpleFifoHandle *>
        (m_output_device_hdlr.simple_fifo_handler)) < param.byte_size)
      {
        // MEDIA_RECORDER_WARN(AS_ATTENTION_SUB_CODE_SIMPLE_FIFO_OVERFLOW);
        return true;
      }

    if (CMN_SimpleFifoOffer(static_cast<CMN_SimpleFifoHandle *>
        (m_output_device_hdlr.simple_fifo_handler),
        static_cast<const void*>(param.mh.getVa()), param.byte_size) == 0)
      {
        MEDIA_RECORDER_WARN(AS_ATTENTION_SUB_CODE_SIMPLE_FIFO_OVERFLOW);
        return false;
      }

    m_output_device_hdlr.callback_function(param.byte_size);
  }
  return true;
}

This is only a temporary solution. If I find other, I will let you know.

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");}
}

Hi @CGM11,

Unfortunately, the current implementation does not support these features.

You can find more information about GNSS on Spresense here:

Hi @Ben-eaton,

To analyze a stack dump the Spresense full SDK provide a tool where you can specify two files as arguments. One is your saved log file, and the other one is the system map file. Doing that you should be able to get the stack trace. If you have build your software with the Arduino IDE you should be able to find where your map file is located in the Arduino IDE log window. Go to File -> Preferences -> Settings -> Show verbose output during and select compilation and when you build your sketch you should be able to find where your build folder is. Normally this folder would be located in /tmp and look something like this:

/tmp/arduino_build_724727/

Fetch the full SDK from github:

git clone --recursive git@github.com:sonydevworld/spresense.git

Change directory to the SDK:

$cd spresense/sdk
spresense/sdk$ ./tools/callstack.py -h
Usage: python ./tools/callstack.py <System.map> <stackdump.log>

Now just specify the location of your files:

./tools/callstack.py /tmp/arduino_build_724727/output.map stackoverflow.log

Hi @Ben-eaton,

You can try this:

  // Open the file for reading
  myFile = File("/mnt/sd0/test.txt");

  if (myFile) {
    // File test.txt exists
  
    // Close the file
    myFile.close();
  } else {
    // File test.txt does not exist
  }

Best regards,
Kamil

NuttX is in compliance with SDA 2.0 specification, so the SD card capacity limit is 32 GB.

Hi @Tony-Prince

Do you use SD card in FAT format?

Hi @Cameron-R-MANN,

Regarding WIN10 + MSYS, try deleting these folders:

• ~/spresense/nuttx/include/arch
• ~/spresense/nuttx/arch/arm/src/board

Then run "make distclean". I hope it will help!

Hi Mark,

Unfortunately, the "voice_command" example is no longer available. This has already been reported and the documentation will be corrected. Thank you for finding this.

Best regards,
Kamil

@the_mutt I'm sorry but I made a mistake. Precision is 10ms, not 10us. The current config can be found here: arduino15 / packages / SPRESENSE /tools / spresense-sdk / 1.1.3 / spresense / release / include / nuttx / config.h. Adding define used in NuttX in the Arduino code will not do anything. If you would like to change something in NuttX then you can use this repository to prepare a package for Arduino: https://github.com/sonydevworld/spresense-arduino-compatible
