[jhaand]

Steps to reproduce Checkout code and configure for ESP32S2. cargo build --features kaluga

Expected: Code compiles successfully

Observed:

error[E0277]: the trait bound `ili9341::DisplayError: std::error::Error` is not satisfied
   --> src/main.rs:860:10

    |          ^ the trait `std::error::Error` is not implemented for `ili9341::DisplayError`
    |
    = note: required because of the requirements on the impl of `From<ili9341::DisplayError>` for `anyhow::Error`
    = note: required because of the requirements on the impl of `FromResidual<std::result::Result<Infallible, ili9341::DisplayError>>` for `std::result::Result<(), anyhow::Error>`

Workaround: Replace on line 860 the )?; with ).unwrap();
