Cargo Features
The following optional hardware drivers can be enabled as cargo features:
adxl343
: ADXL343 accelerometer supportkeypad-unproven
: (alpha) support for button input via the keypad crate
To enable them, use the features
option when adding a crate dependency to
your Cargo.toml:
[dependencies]
trellis_m4 = { version = "~0.1", features = ["adxl343", "keypad-unproven"] }
Or when running an example:
$ cargo hf2 --release --example neopixel_keypad
error: target `neopixel_keypad` in package `trellis_m4` requires the features: `keypad-unproven`
Consider enabling them by passing, e.g., `--features="keypad-unproven"`
Just follow the instructions to add --features like
cargo hf2 --release --example neopixel_keypad --features="keypad-unproven"
