While the project does have examples, even a simple example such as
blinky doesn't really cover how to get started if you don't want to use
a template.
* Use rp2040-hal in all example (possibly through their bsp)
Some of the examples were using the cortex_m_rt::entry method which
misses the device specific spinlock re-initialisation.
This commits makes the usage more consistent by using rp2040_hal exported
macro as the only `entry` method used across examples.
* Modifies:
* Cargo toml to include arduino_nano_connect package
* README to update documentation to reflect a board being added
Adds:
* Basic support package for Arduino's RP2040 Nano Connect board
* blinky example
