option to get the config out of a whole board dump
now you don't need to fiddle with specific byte ranges of a dump, you
can just dump the whole board if that's more convenient, and
visualize-storage will parse that

also more testing in general

# GP2040-CE Binary Tools
Tools for working with GP2040-CE binary dumps.
## Dependencies
Interacting with your board (e.g. getting dumps, etc.) requires [picotool](https://github.com/raspberrypi/picotool), and
currently the expectation is that you can run it yourself before invoking these tools. That may change one day.
## Installation
```
% git clone [URL to this repository]
% cd gp2040ce-binary-tools
% python -m venv venv
% source ./venv/bin/activate
% pip install -e .
```
At some point we may publish packages to e.g. pypi.
### Development Installation
As above, plus also `pip install -Ur requirements/requirements-dev.txt` to get linters and whatnot.
## Tools
### visualize-storage
**visualize-storage** reads a dump of a GP2040-CE board's flash storage section, where the configuration lives, and
prints it out for visual inspection or diffing with other tools. It can also find the storage section from a GP2040-CE
whole board dump, if you have that instead. Usage is simple; just pass the tool your binary file to analyze along with
the path to the Protobuf files.
Because Protobuf relies on .proto files to convey the serialized structure, you must supply them from the main GP2040-CE
project, e.g. pointing this tool at your clone of the core project. Something like this would suffice for a working
invocation (note: you do not need to compile the files yourself):
```
% visualize-storage -P ~/proj/GP2040-CE/proto -P ~/proj/GP2040-CE/lib/nanopb/generator/proto memory.bin
```
(In the future we will look into publishing complete packages that include the compiled `_pb2.py` files, so that you
don't need to provide them yourself.)
Sample output:
```
% visualize-storage -P ~/proj/GP2040-CE/proto -P ~/proj/GP2040-CE/lib/nanopb/generator/proto ~/proj/GP2040-CE/demo-memory.bin

### Dumping the GP2040-CE board
These tools require a dump of your GP2040-CE board, either the storage section or the whole board, depending on the
context. The storage section of a GP2040-CE board is a reserved 8 KB starting at `0x101FE000`. To dump your board's storage:
```
% picotool save -r 101FE000 10200000 memory.bin
```
And to dump your whole board:
```
% picotool save -a whole-board.bin
```
