This driver is still work-in-progress and it's API may not be stable. Pull requests welcome!

## Examples

For examples, have a look at the [examples/](examples/) directory.

A very simple example:

```rust

use lp586x::{ConfigBuilder, Lp586x, PwmAccess};

let config = ConfigBuilder::new_lp5864()

    .pwm_frequency(lp586x::PwmFrequency::Pwm62_5kHz)

    .maximum_current(lp586x::CurrentSettingNonT::Max40mA)

    .data_mode_8bit(false); // disable vsync for simplicity

let mut led_driver = Lp586x::new_with_i2c(&config, i2c_bus, 0x40, &mut delay).unwrap();

let mut framebuffer = [0u8; 72];

framebuffer[0] = u8::MAX;

// display current framebuffer

led_driver.set_pwm(0, &framebuffer).unwrap();

```
