unable to identify device

thecatsalami

Hi, I have searched long through the forum to see if I could fix this but I've had no luck. When using the Trill Craft sensor I have it works when running the detect-all-devices code, however does not run for any other. Giving an error stating "unable to identify device" and "unable to initialise" with the "makefile/runide" error

I've attached photos to show the program working with detect-all-devices, but then failing with the craft-visual. I hope this isn't something easy I've missed but I am confused as to why it will detect the device on one but not the other. This has worked for me in the past but all of a sudden has stopped.

Thanks in advance

As you see here, the default address for Trill Craft is 0x30. In your case, the sensor is detect at address 0x36 (probably because the address was changed via the address pads). To use Trill Craft examples, you need to edit the setup() lines by specifying the address. For instance, this

	if(touchSensor.setup(1, Trill::CRAFT) != 0)

should become

	if(touchSensor.setup(1, Trill::CRAFT, 0x36) != 0)

giuliomoro Thanks, I needed this info!

Thank you Giulio, that's working now. I should've realised that tbh, but I appreciate your help

Hello,
I'm having the same issue and changing the address is not working for me. I tried all the additional address for the trill craft and i m still receiving this message. Could be another problem? Also the connections are fine...

Also receiving this message when i tried 0x30:
Trill: error while reading from device Craft at address 0x30 (48): -1 of 60 bytes read (error: 121 Remote I/O error)

thank you!

Can you try running the following command in the console at the bottom of the IDE:

i2cdetect -y -r 1

and post the result here?
What board are you using? Is it Bela, BelaMini or a CTAG?

christie

Hi, thanks for your reply, I'm using Bela mini, this is the result

Right, so the device is not showing up at all. Did you double check the wiring? Do you want to send a picture of your setup? Did this device work previously?

christie

I doubled check the wiring and it seams fine to me, I tried to make a photo, don't know if it is clear but i connected ground, +v to 3.3v, sda and scl to analog 4 and 5 and it said on the example instructions, maybe the analog pins should be written on the code? Although none of the trill craft examples are working. I've already used my Bella mini but I received only few days ago the trill craft and it never worked. I will try with arduino tomorrow and see if i manage with t instead

The picture is dark, too dark to see, but it would definitely seem that you are not using the I2C pins on the P2 header, it looks like you are using the analog in header. Check the location of the I2C1 SCL and SDA pins in the pin diagram in the Bela IDE

christie

Yes, I just realized that I connected them very quickly to take the photo to the wrongs pins the analogs ones but they were connected to the right ones on the second columns that corresponded to SCL and SDA pins

giuliomoro

Right, would you mind sending a clear picture of a setup that you reckon should be OK so we can double check?

christie

Ok, I hope those are better photos because my phone is not the best

ALso today is doing this:

I connect just a wire at the 1 channel of bella trill to see if any value is changing and than is where the error is appearing. I m using the example trill craft sound. If i don't connect any wire to the channels this is the message:

So maybe I'm doing something wrong with the channels?

giuliomoro

christie If i don't connect any wire to the channels this is the message:

That means it is working.

christie it seems that has some connection fails when i connect wires to the capacitive channels, don't know if is the trill at this point or my protoboards

What's the other end of the cable connected to?

christie

it seems that has some connection fails when i connect wires to the capacitive channels, don't know if is the trill at this point or my protoboards

christie

To nothing was just testing with the wire and the touch of my fingers

giuliomoro

not sure what to say at this point... for sure it shouldn't stop working when you touch it ... are the wires soldered to the Trill Craft? It may be a loose connection?

christie

no they are not soldered, I'm going to do it and try again at this point
