Hi people!
Is there anyone who has used Capacitive Sensing oscillator ?
Is very interested in how it works
Please recommend how I should get started:-)
Best Regards

Hi Dmtri!

I have asked the same thing : http://www.matrixmultimedia.com/mmforum ... gu1#p28446
But it seems that there is not someone who has tried it in FC. But try to look at this link. there is another link from (PCBheaven) that shows a good example. Maybe it can give you an idea to do it in FC. if you can, I am very interested, as I write, you can even change as you wish.

Does anyone have an idea?
Thanks

Here is a very basic example of cap touch in Flowcode v4.5.

For a better cap touch output you should really repeat the loop several times and take an average of the reading.

Hi Ben!

Thak you for your examble, but I have unfortunately absolute no experience with C. Is it difficult for you to "Compile it to Flowcode".

Hello Jorgen,

Unfortunately coding the ADC channel and other parameters into a custom component would be quite tricky without creating a specific component front end and we are currently flat out with v5 development. I will have a think on it and see what I can come up with. There is not too much C code in the file. I think the main bit you have to change is the bits that assign the specific ADC channel.

Hi Ben!

Ok Ben, thanks for your reply. Yes, I could imagine it's hard to do in CF. Still look forward to Ver.5.

best wishes

Jorgen.

Hello,

I have improved the example a bit to include a variable to control the ADC channel in use and also included a loop to help filter the cap touch signal.
