Usage

Using this driver

Add the following to your Cargo.toml:

[dependencies]
cu-rp-sn754410 = "0.2.3"

In your Copper RON config file, add the following:

    tasks: [
        (
            id: "dst",
            type: "cu_rp_sn754410::SN754410",
        ),
    ]

There is no config for this driver.

When you connect this driver to the rest of the system you need to use the cu_rp_sn754410::MotorMsg message type.

    cnx: [
        (src: "src",  dst: "dst",   msg: "cu_rp_sn754410::MotorMsg"),
    ],

In this message the field current_power is the power that you want to apply to the motor. It is a value between -1.0f32 and 1.0f32. The negative values are for the reverse direction.
