Hi Daniel,
I have a solution for you. First of all, use the Ethernet library from my fork (https://github.com/kamtom480/Ethernet). Secondly, you need to connect some pins on the Ethernet shield. Connect pins 11 (MOSI), 12(MISO), 13(SCK) located on the ICSP Header with pins 11, 12, 13 located on the Digital Header (11 -> 11, 12 -> 12, 13 -> 13). Now you should be able to use Ethernet with Spresense board. If something does not work or is unclear then let me know.
Best regards,
Kamil
@the_mutt CONFIG_USEC_PER_TICK is set to 10000, so the precision is 10 us. See https://github.com/sonydevworld/spresense-nuttx/blob/master/sched/Kconfig#L96
@nicibume Could you please modify the spresense/externals/nnablart/nnabla-c-runtime/src/runtime/runtime.c file as shown below?

This adds 2 extra logs. Please send me an output from your serial console after making the change.

@niciBume You get these errors because you didn't make the changes I showed in step 2 to the spresense/externals/nnablart/Makefile.
This adds missing files to the Makefile that were added in the new version of the NNabla C Runtime library.
You can use the code from step 2 as .patch and apply it to your Spresense SDK repository.
Best Regards,
Kamil Tomaszewski
@nicibume I have another idea. Please use the latest version of NNabla, but update the NNabla C Runtime Library used by Spresense.
To do this:
$ cd externals/nnablart/nnabla-c-runtime
$ git fetch
$ git rebase origin/master

Could you please try the converter from Nnabla version 1.12.0?

Hi @niciBume
Could you please try to find out where exactly dnn_runtime_initialize returns error?
https://github.com/sonydevworld/spresense/blob/87f81d9c35c7d05d6a75e9177b45d6cbe8d8c063/sdk/modules/dnnrt/src/runtime/runtime_nnabla.c#L66
Without it, it's hard to say what exactly doesn't work because this error only says that something didn't work in the NNabla C-runtime library.
As for the conversion, I think you should use these commands. This is how it is described in the documentation:
$ nnabla_cli convert sony.onnx sony_nabla.nnp
$ nnabla_cli convert -b 1 sony_nabla.nnp sony_nabla.nnb

The current implementation of the Camera library does not support Camera.takePicture () function within the interrupt service routine (ISR). Kernel panic is expected. Unfortunately, but the same will be with the Spresense SDK.
Hi @MezmerizeR
Have you tried to use an operating voltage of 3.3V on the GPIO pins?
https://developer.sony.com/develop/spresense/docs/hw_docs_en.html#_setting_operating_voltage
If you change it then you also need to connect VCC to 3.3V and not to Vout.

Hi @MezmerizeR
I don't know what library you use but I guess this one: https://github.com/bogde/HX711
They support fast CPU boards here: https://github.com/bogde/HX711/blob/bc5a7e5a0d518a0f384bd30105cdce0773e20028/src/HX711.cpp#L24, but unfortunately Spresense is not added there.
Could you please try adding || defined(ARDUINO_ARCH_SPRESENSE) here in your local library?
Best Regards,
Kamil Tomaszewski
@Jorge-Enrique I think it shouldn't be a problem. The SPI interface is what you should use for Spresense to communicate with the display.
Hi @Jorge-Enrique,
I used the displays with the ILI9341 driver so I can recommend them to you. You can find displays of various sizes that have this driver.
I hope it helps you!
