Hi guys did you check if the print of the pins is aligned with the headers number views? at last we decide to not include the writeAll?

[pnndra]

we need to also add the writeAll() API

[Rocketct]

ookk so let me check this if work correctly i'll merge and on top of this i'll push the writeAll()

[Rocketct]

this works fine i'm going to merge it and made the new PR for the write all
