Embedded Rust Raspberrypi Pico (RP2040) OLED Example

This project was based off of the [Project template for rp2040-hal](https://github.com/rp-rs/rp2040-project-template). Check their README for setup.

The logic to drive the display via SPI has been ported from the [TIVA-C example](https://github.com/HerrMuellerluedenscheid/tm4c-oled-example). The OLED display is the exact same SPI driven SSD1309.

Wiring

OLED pin	RP2040 pin
CS	GND
DC	GP5
RES	GP6
SDA	GP3
SCL	GP2
VCC	3.3V
GND	GND

Run the example

I used [pyOCD](https://pyocd.io/docs/installing):

pyocd gdbserver -t rp2040_core0

You may want to change the runner from arm-none-eabi-gdb to e.g. gdb-multiarch dependent on the platform and setup you are using.

Then:

cargo run
