If you have access to a logic analyzer set the it to decode async data, auto baud to see what you can conclude.

voidptr, it's best you not return any any comments.

Not the best solution, but, when I talked to Saleae, they are looking at having a glitch filter on/off option in the software.

Only adjustment available, Image one:

One more good reason to have a ground plane, image two:

Used these many years ago.
Made a huge difference at high frequency.

I hate this  "You are already logged in" problem with the Forum!

@noobdude
Good explanation here:
http://www.vishay.com/docs/73217/73217.pdf

Comes down to the charging of the input capacitance through the driving resistance.
T=RC

11  Using Arduino / General Electronics / Re: Trying to calculate gate charging current/choose a gate driver for IRLB3813 on: September 28, 2014, 05:06:06 pm
The input capacitance says 8420pf

We need to see all your sketch.

You could rough cut the holes in the box then add a plastic bezel over the hole(s) mark them from the back, then cut the holes out with hand tools. IMO pastic is usually easier to work with and finish.
I use this material for the bezels, gravoply.
Google               gravoply images
