Might be different per device.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">It's based on a patch I got from Wolthera, which was discarded/unfinished because the output of the sensor remained "blobby".</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I added a smoothing formula to the speed output :</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">output_speed = current_speed * 0.1 + last_speed * 0.9</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The used numeric values are either eyeballed or wild guessed from usage. There's certainly room for improvements on this patch.</p></pre>

Results are noticeable improvements when painting strokes at different speeds with the fix.</p>
