Driver for ROHM BD18378 12CH LED Driver IC

A Rust driver for the ROHM BD18378 12CH LED Driver IC, suitable for embedded applications. This crate supports embedded-hal traits and is fully compatible with #![no_std] environments.

✨ Features

• Supports the ROHM BD18378 12 channel LED driver IC
• Communication via SPI interface
• Platform-agnostic via embedded-hal::spi traits
• Supports #![no_std] environments

📦 Installation

Add the following to your Cargo.toml:

[dependencies]
bd18378 = "0.1"

or add it via command line using:

cargo add bd18378

🔮 Example

#![no_std]
use bd18378::Bd18378;
use embedded_hal::spi::SpiDevice;
use embedded_hal_bus::spi::{ExclusiveDevice, NoDelay};

fn main() {
    // Initialize the SPI interface
    let spi = ...; // Your SPI implementation here
    let cs = ...; // Chip select pin

    let mut spi_dev = ExclusiveDevice::new_no_delay(&mut spi, &mut cs).unwrap();

    // Create a new instance of the BD18378 driver
    let mut led_driver = Bd18378::new(&mut spi_dev);
    
    // Initialize the driver
    led_driver.init().ok();

    // Set the brightness of channel 0 to maximum
    led_driver.set_channel_calibration(0, 0x3Fu8).ok();

    // Turn on channel 0
    led_driver.enable_channel(0).ok();
    led_driver.update_all_channels().ok();
}
