I2C issue updated?

[greg-norris]

Has the I2C issue been resolved concerning the screen? I would like to work on a Display tutorial, but we would also like to get the BrainPad to a known state? Our engineers don't want to flood the site with issues from our end with things that are only temporarily down or changing.

The changes are in beta with the latest c++ bits but I haven’t tested them.

Do we have a way of testing it locally? with PXT not codal I mean.

[greg-norris]

The current local version, I'm running of PXT-BrainPad display currently doesn't work.

[pelikhan]

Yes you can test locally. I've added a note in the README on how to update the CODAL tag (66609fc). Once the tag is updated, you can write a test program in libs/brainpad/test.ts and run pxt deploy.

[greg-norris]

It appears to still be grabbing an older version of mbedos from git. When tested locally have to manually add missing functions in I2C to get it to work.

Make sure to clean your build folder when updating a tag. pxt clean From: greg-norris <[email protected]> Sent: Friday, May 18, 2018 6:20 AM To: Microsoft/pxt-brainpad <[email protected]> Cc: Peli de Halleux <[email protected]>; Comment <[email protected]> Subject: Re: [Microsoft/pxt-brainpad] I2C issue updated?

When using the beta site the display doesn't work. The tutorials are all correct as you noted in the call.

[pelikhan]

You should be able to repro the display issue locally. The format changed. The relevant C++ line is here: https://github.com/Microsoft/pxt-brainpad/blob/master/libs/screen/screen.cpp#L31
