Uart big len data locks dashboard

[pinkflozd]

I tried to debug why the dash is locking up. Seems that the dash receives or sends a lot of data at once. when accelerating fast and with higher switching frequency.

(if (and (> len 0) (< len 10)) seems to fix it, i think it's because of the cpu spikes the dash receives a lot of data at once

(print len) output:

7

9

85

How to reproduce the dash bug: Set switching frequency to 45khz, connect with USB, enable live data, add a (print len), and try to hit the throttle fast, it happens on almost all fast throttles DON'T DO IT ON ROAD!

Yes. I have talked about this issue already with @vedderb on https://github.com/vedderb/bldc/issues/572 but have not fixed it yet. Now I can look into it. :)

The array buf is only size 64 and as soon it reads a len of 85 is being read it will crash.

Still need to test if this actually fixes the issue.

Tested now. It does fix the issue, but it one too high. I checked if len is equal less than 60, but it has to be less than 60.

works fine.

does.

Now changed it.
