@andrewmruddy There're some examples for I2C use with `stm32f1xx-hal` in the `ssd1306` crate, e.g. https://github.com/jamwaffles/ssd1306/blob/master/examples/graphics_i2c.rs

@jounathaen I wouldn't want to add external dependencies for examples and unfortunately I2C without connected devices is not too impressive/useful.

@jounathaen Oh sure, I definitely agree we should have proper code documentation with logical code snippets.

We also have lower level networking with examples in the https://github.com/adamgreig/stm32f4-smoltcp-demo
