@rajeshdoshi it depends on the panel hardware It is correct that colors may shift pixel by pixel with a lot of panels. This is because the Clock-Signal for the first...

Also, because all signals are refreshed after each panel, the error would be really consistent. The shift will only happen on the loop-back from one color channel output to the...

That's what may happen here in the Video @2dom mentioned: https://twitter.com/MLE_Online/status/1192265470117695488 These panels are rotated 90°, a row goes from top to bottom. You can see that the shift is...

You should step back for a moment and check if your setup even works with one panel. It looks like it is not, groups of 8 rows each are actually...

That doesn't look too bad. Your color order actually is `BBGGRR` so please try `setColorOrder(BBGGRR)` in regular code (it won't affect the pattern test). Also, I assume the video was...

why did you change to begin(4)? You must use begin(8). Can you try this (untested)? Also, please put your code in code tags when you post here. ``` #include #include...

Great... So everything is okay except that row 0-7 and 8-15 as well as 16-23 and 24-31 need to be swapped. I'm not sure if a suitable scanPattern exists. It...

Same as #198 ... needs implementation of a new scanPattern, I guess

Actually it is a problem, because the order is also swapped in the footprint/package. The pin next to RX is GPIO5.

Okay, I came up with a working example: https://github.com/xsrf/picoplanet/tree/platformio/example/platformio I have slightly different pin definitions in [variant.cpp](https://github.com/xsrf/picoplanet/blob/platformio/example/platformio/variants/bleeptrack_picoplanet/variant.cpp#L22) and [variant.h](https://github.com/xsrf/picoplanet/blob/platformio/example/platformio/variants/bleeptrack_picoplanet/variant.h#L79) though. Since I used the Trinket M0 as template, I kept...
