Copper Driver for the TI SN754410 Quadruple Half-H Driver

Overview

The SN754410 is a quadruple half-H driver that can be used to drive motors, solenoids, and other inductive loads. It can drive up to 1A of current at 4.5V to 36V. The driver is capable of driving two motors in both directions using the 2 PWMs generators from the Raspberry Pi.

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.
