yep, or I think this should work:

```rust
        match try_join4(i2c1_result, i2c2_result, i2c3_result, i2c4_result).await {
            Ok(_) => { },
            Err(e) => error!("I2C Error during async write-read: {}", e),
        };
        let keyboard_read_total_us = Instant::now().as_micros() - keyboard_read_start_us;
        info!("Read keyboard in {}us", keyboard_read_total_us);
```
