sparkleBatch failed

[lanzafame]

On commit 2870383, I uncommented the sparkleBatch() call in POC/ts/index.tx, after building and running, I got the following error:

$ npm run-script poc-ts

I am guessing this is probably because I am yet to upgrade the 5Qs firmware at all as I don't have a windows box. But thought the error report may still be useful.

OS: macOS 10.13.5

Thanks for all the work you are all putting into this 👍

Thanks for the report!

I don't have a Mac, so I can't attest to the quality of these suggestions:

• try running the software as root, possibly the device is protected (it is on Linux)
• ensure you're on NodeJS v8 and rm -rf node_modules; npm install
• use a friend's (if you have any) Windows device to install the firmware update or use a virtual machine

If you figure it out, please let us know so we can document it.

@lanzafame I'm seeing a similar issue. After a little while of running sparkleBatch, it seems like we get an error.

Also, thank you very much for submitting the report, as you've helped us test that new firmware version check 👍

[chris13524]

@lanzafame When you run the script, does your keyboard perform the animation and then error out after pressing a few keys? Or does it immediately error without performing any animation?

[lanzafame]

@chris13524 depends...

TL;DR it never performs the animation

So I was just testing things and came across a few things:

• running poc-ts renders the brightness button ineffective
• poc-ts can set the brightness without erroring
• the animation may result in a static pattern being displayed, see here

and lastly, this may be my inability to write JS but adding a console.log before after the setBrightness causes the firmware version and the additionally log not to be logged out before the program errors (same error as above).

Hopefully, that is some useful information.

@lanzafame,

I think you may have caught the code in a bit of a transition phase. Try grabbing latest and attempting again. In issue #12 we have another user with a similar firmware. My keyboard was reporting back a 147.x firmware version for a while but now it is reporting the common 7.3.253.18 version number which seems to be what DAS has out as the latest.
