Thanks for following up @TE-KarlKomierowski ! I'll look into the PDM microphones.

I'v just attempted to re-install the SDK on my Raspberry Pi (for the sole purpose the running the flasher - full builds still require an Intel system) but it seems it now fails at install-tools stage. which is a shame. 😞

Hi @petrokikundi

I have forwarded your question to people with more knowledge about the requirements are in the latest release.

Hi @TE-AmitSa ,

Unfortunately we can't write any new software on request but only provide support if you decide to write this driver by your self.

The following link might be helpful for you.

Hi @TE-KarlKomierowski thanks again, didn't notice this until today, will havea look ASAP and get back on this. Thanks again. Cheers, Vivek

Hi @MARCO ,

If you have commercial plans/questions of this type I would recommend you to use this form to contact Sony: Purchase Inquiries

Happy new year.

@KamilTomaszewski Thank you for this wealth of info.

Hello @ahoudeau

The source code that was used by the prepare_arduino.sh script is version 1.4.2. You can check the git log and see the tag.

Version 1.0.0 here does not apply to the Spresense Arduino Library version but only to the version of your custom Arduino15.

You can change this to 1.4.2. Change all occurrences of 1.0.0 to 1.4.2 in the Arduino15 folder.

It will not change anything in the source code. Everything will be the same. Only the Arduino IDE will see that this is a different package.

You shouldn't have any problems. Maybe try:

In the Arduino IDE go to Tools-> Board-> Board Manager... and remove Spresense.

Go to %userprofile%\AppData\Local\Arduino15 and remove packages and package_spresense_index.json and other files that have spresense in their name.

Copy packages and package_spresense_index.json from spresense-arduino-compatible/Arduino15 to %userprofile%\AppData\Local\Arduino15

In the Arduino IDE go to Tools-> Board and select Spresense.

Do you use automatic updates in the Arduino IDE?

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 @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.

Vivek

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 @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👍
