SparkFun Navigation Switch Breakout Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    any instructions/sample sketches for Arduino?

    There is a useful discussion (for beginner's like me) on using this switch here, including some sample code with debouncing, etc.. The code is written for an Olimex LPC-P2148 board, and I toggle the two LEDs depending on whether the switch is up, down or depressed.

    include

    int main(void)
    {
    IODIR1 &= 0x03800000; // P1.23...25 as inputs
    while (1)
    {
    // Check button state
    if (!(IOPIN1 & 0x02000000)) // T (P1.25)
    {
    // Select Button Pressed
    }
    if (!(IOPIN1 & 0x01000000)) // 2 (P1.24)
    {
    // Down Button Pressed
    }
    if (!(IOPIN1 & 0x00800000)) // 1 (P1.23)
    {
    // Up Button Pressed
    }
    }
    }
