Trill example fails #2

Closed DhruvaG2000 closed 3 years ago

DhruvaG2000 commented 3 years ago

I was just trying out the Trill examples and it seems like there is an i2c bus issue.

it may well be that you are passing the wrong i2c bus as an argument to setup(). I think we went through this in early July ? Use i2cdetect to see what i2c bus the Trill is actually connected to

DhruvaG2000 commented 3 years ago

I think it maybe on i2c-2

$ i2cdetect -r -y 2

That would look fine for Trill Bar

DhruvaG2000 commented 3 years ago

Changed the following line in the example:

 88         if(touchSensor.setup(2, Trill::BAR) != 0) {

and it worked

Should we also add the IS_AM572x flag to the examples?

giuliomoro commented 3 years ago

No not for now. That should be in the documentation.
