Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Over at my repos readme I explore and explain how 10-bit i2c addressing is fully supported on the RP2040 but the RP2040 datasheet suggests otherwise in the case of slave mode operation. I have another forked repo with just the updates required to update the SDK to fully support 10-bit i2c addressing.
Basically I left all existing functions alone (obviously), and added about 13 new functions with identical names to the existing i2c functions but with a _10bit qualifier on the end.
But I should ask before doing so, why was 10-bit i2c addressing left out of the SDK ? Was it simply because it's not used much?
If you all decide it's something worth adding to the SDK, I'll open a PR against this issue.
