And if you could squash your commits to get rid of all the unrelated churn, that'd be great 👍 EDIT: Thanks 😃 |

@peterharperuk I'm not a "native C programmer" - does my suggestion of these macros make sense? Is there perhaps a better name for them? 🤷♂️

I'm not a big fan of the names as they don't really say what they're doing. Maybe inline functions would be better - and type safe (FLATTEN5 takes a uint64_t?). But I'm not sure it's worth more changes.

@peterharperuk Perhaps e.g. FLATTEN2 could be renamed to COALESCE_2_BYTES ?
@Louis31423142 If you wanted to use inline functions, I think you could do something like:
static uint16_t coalesce_2_bytes(uint8_t* bytes) {
return (bytes[0] << 8) + bytes[1];
}(but I agree that it's probably not worth it)

Probably makes sense to update this URL too. https://www.raspberrypi.com/products/raspberry-pi-pico/
Although thinking about it, I wonder if something like this works, or if it's too wordy?

WDYT @peterharperuk ?
