Looks like I2C.readFrom already returns an Uint8Array, so I think you are doing a double allocation.
Not sure, but I think your memory usage might be smaller with just:
```
var data = read(register, length);
```
Or not, or might not even be measurable, if that allocation is just in a small function, and the GC frees up memory...

```
is the same size as 
```
var data; data.set(read(register, length));```

This function is used quite often in the examples:
