@Arco You're welcome.

Unfortunately, TensorFlow is currently only supported on the NuttX SDK.

@aaronm Awesome that you got it working and thanks for sharing your findings!

Ok, thanks for that. Not currently, but I probably should do though.

Hi @dhalbert,

CXD5602 has 7 endpoints.

However CXD5602 doesn't support a same endpoint number with different direction IN and OUT (e.g EP1 OUT & EP1 IN cannot exist together). The only exception is EP0.

I hope it will help.

Hello,

I download and build AOSP 11 according to instruction given at https://developer.sony.com/develop/open-devices/guides/aosp-build-instructions/build-aosp-android-android-11-0-0/

After to flash imagea to the sony xperia 10 device, wifi on this devicea do not work.

Best regards,

Hi @Berkay-Isik
Spresense has 4 PWM with 1 channel each:

/dev/pwm0- pin 6
/dev/pwm1 - pin 5
/dev/pwm2 - pin 9
/dev/pwm3 - pin 3

If you want 2 PWM outputs, you need to open two devices (open()) and then call ioctl() on each of them.

You can look at the PWM implementations in CircuitPython: https://github.com/adafruit/circuitpython/blob/main/ports/cxd56/common-hal/pwmio/PWMOut.c

I hope it will help. If anything is unclear please ask.

@TE-KarlKomierowski Thanks for the advice Karl. It will likely not be with color.. I just used these beads as examples .. to see if it can be done easily. thought that if the pellets are changed to other items, neural networks can be used to train new objects and models can be replaced to identify new items. .

Hi AbelChT,

The fastboot/flash mode are stored on a partition that is not available to users and should be fairly safe to assume that if you follow the guides provided on our website there will not be any issue.

The kernel (boot.img & recovery.img) is stored on separate partitions and even if you flash a broken kernel/OS you can always go to the fastboot (blue light) / flash (green light) mode to recover your device. You can always use the flashtool to flash the Sony image and recover from a bad OS update if your custom ROM does not boot.

Please note that during the unlock process the userdata is wiped.

Best regards

One workaround might be for the application to remember the previous input and then select it x seconds after issuing the command to 'power on'. I'm guessing the soundbar won't tell you the current input when it is in standby mode, but if it does you could query the current input before powering on instead of storing the last used input.

@david Thanks for your great effort regarding this issue. I'll be trying out this new letter in the app store to check if it passes the barrier.

Hi @Jodie_space!

Unfortunately there is no built in support for recording to a video file on the SD card. There are two camera data streams available: one for taking still pictures and one for showing a preview video like you have in a "regular" digital camera. No support for actual video recording.

Now, it doesn't say exactly what your project is supposed to do or what you want to use the video for, but perhaps it would be possible to generate the actual video file as a post processing step? This might work If you don't intend to use the actual video file on the Spresense board itself after recording. In that case you could save the frames from the preview video as separate image files on the SD card instead of displaying them on a display etc. Then, when the recording is finished, plug the SD card into your PC instead and combine them into a video file using an external tool such as ffmpeg.

This workaround might not work for you - it depends on what you want to accomplish - but it is the simplest solution I can come up with.

I found this similar thread that might be interesting to you:

Hi @monotaskr,

Nice to hear about your ideas! Unfortunately I am not able to help out with the actual project design so I will just give some generic recommendations to help you get started

As a first step I'd suggest you have a look at the sample applications available in the Spresense SDK and/or Arduino library if you haven't already. Getting an idea of how audio works in Spresense and what it can do might help you decide the scope and direction of your project. The audio system might seem a bit complicated at first, but start playing around a bit with the samples to get a feel for it. There are several audio related apps in both the Arduino and SDK development environments, but remember that they are just examples. Don't let their scope limit you!

Then you can start to think about what sampling devices you think are suitable for your project and figure out what adaptations might be needed to connect them to the Spresense mic inputs.

Here are some general pointers to interesting audio related sections in the documentation:
https://developer.sony.com/develop/spresense/docs/sdk_developer_guide_en.html#_audio_subsystem
https://developer.sony.com/develop/spresense/docs/arduino_developer_guide_en.html#_audio_library
https://developer.sony.com/develop/spresense/docs/hw_docs_en.html#_how_to_use_microphones

You might also find this forum thread interesting if you haven't seen it already:

I hope it helps!

@david ok, thanks anyway for your quick responses. Much appreciated.

Hello Neo,

Those files were released as a best effort for community but Android 10 is not officially supported for Xperia X
