So, dropped it in and it runs which I am seeing as a small victory.

Unfortunately saying...

"Bela: Couldn't find touch controller"

sensor lights are on and 99.9% all connections are good so just checking through.

Thanks again

Can you show your wiring? Also, that assumes that the device is using its default address of 0x48. Also, with the sensor connected run in the console at the bottom of the IDE:

i2cdetect -y -r 1

and show the result here

Cool thanks so much. OK two pics. I think it's using the default address.


ok I amended the repo, get the updated version and try again.

That works.... Amazing thanks so much. So now I just need to figure out how to send it out via OSC to SC. What's the best approach there?

OK I updated the repo so that it sends to localhost:1234 an OSC message to address /tsc containing four integers with the values you were previously seeing printed. For prototyping purposes , you may want it to send to the host computer instead, in which case replace "hostAddress = localhost" with "hostAddres = 192.168.7.1" (or 192.168.6.1, depending on what address your computer has on the point-to-point network with Bela), also adjust the port number to taste.

I can receive this with this simple Pd patch, surely it's easy enough to do in Supercollider as well:

If this works as expected, then use the instructions here https://learn.bela.io/using-bela/bela-techniques/running-a-program-as-a-service/ to run it in the background while you run a proper Bela program on the side.

That's great...thanks.
Something going wrong on my end though.

Wow you are amazing... looks like it's working. The running as a service looks well documented so will try that later.

Do you have one of those buy me a coffee type things?

Thanks!!

    Any program run this way will not be able to access Bela’s audio, analog and digital I/Os while another Bela program is running.

    Just a bit confused by this bit. Does that exclude the I2C bus then?

    I was just think how cool this is and setting it up this project to read a few analog inputs/switches and then just having SuperCollider receiving OSC and making sound.

    Is that possible?

    Many thanks Simon

      simonb Bela’s audio, analog and digital I/Os

      these are all handled by a "Bela program" and there can only be one of these running at any time, which will take control over all of those, processing them at audio sampling rate and with low latency. "digital I/O" here refers to the 16 GPIOs handled directly by the Bela core, which are those highlighted in the pin diagram for your board. This does not include devices connected over other digital busses e.g.: I2C, UART, SPI, which can he handled by any program running on the board. You can still access the GPIOs that are not managed by Bela and are not otherwise used by Bela using the Gpio class and integrating it within this same program. See more details here.

      simonb I was just think how cool this is and setting it up this project to read a few analog inputs/switches and then just having SuperCollider receiving OSC and making sound.

      If you are processing audio via scsynth, you'll have to process all of those also via scsynth, there are dedicated ugens to do that: AnalogIn, DigitalIn, DigitalOut, DigitalIO. You can then use sendReply() if you want to send a snapshot of the input values back to sclang.

      simonb Do you have one of those buy me a coffee type things?

      No thanks, I don't drink coffee. Just tell all your friends about the good experience you've had here.

            @simonb I updated the library , would you be able to help me test this by repeating the step here with the latest files from the repo and using Bela's latest dev branch?

            Hi @giuliomoro

            I am just going through the steps above to make this Library on another Bela board.

            Just run into this Error. Any ideas how to fix it? Many thanks

            You need to udpate the Bela core code to the dev branch on the board where you build this.

            Thanks!

            I am back on this on a OG Bela not mini. Updated to this.

            Version details
            Image:
            v0.3.8h, 5 January 2023

            Core code:

            from file 'Bela-dev'
            via 'update_board'
            Update was successful
            Git desc: 'e43b8abe-dirty'

            Downloaded the the Adafruit_TSC2007-Linux-master from above. Wired up everything correctly but now I get the same message as above.

            Then tried this.

            i2cdetect -y -r 1

            And get this.

            Any ideas what to try next?

            I don't know why that doesn't work. I suspect that this may fix it, can you try?
