use embedded_hal_async::i2c::I2c in I2CDisplayInterface if feature 'async' is enabled to enable embassy_embedded_hal::shared_bus::asynch::i2c
With embassy_embedded_hal::shared_bus::asynch::i2c you can share the same i2c for multiple devices. I.e.
use embassy_embedded_hal::shared_bus::asynch::i2c::I2cDevice; use embassy_sync::mutex::Mutex; use embassy_sync::blocking_mutex::raw::NoopRawMutex;
static I2C_BUS: StaticCell<Mutex<NoopRawMutex, Twim>> = StaticCell::new();
let config = twim::Config::default();
let i2c = Twim::new(p.TWISPI0, Irqs, p.P0_03, p.P0_04, config);
let i2c_bus = Mutex::new(i2c);
let i2c_bus = I2C_BUS.init(i2c_bus);
// first device on the bus
let interface = I2CDisplayInterface::new(I2cDevice::new(i2c_bus));
let mut display = Ssd1306Async::new(interface, DisplaySize128x32, DisplayRotation::Rotate0).into_terminal_mode();
//second device on the bus
let mut ms5611 = Ms5611::new(I2cDevice::new(i2c_bus), None).await.unwrap();
