Struct rusty_nail::dispenser::AdafruitPeristalticDispenser::AdafruitPeristalticDispenser

pub struct AdafruitPeristalticDispenser { /* fields omitted */ }

An implementation of a Dispenser which works with the Adafruit 12V DC Peristaltic Pumps. These pumps have the following parameters:

• Working Temperature: 0℃ - 40 ℃
• Motor voltage: 12VDC
• Motor current: 200-300mA
• Flow rate: up to 100 mL/min (1.6666... mL/second)

This will allow us to create a controller for the dispenser which should output ~100mL/min pretty reliably and scale that flow rate.

Methods

impl AdafruitPeristalticDispenser

fn new(chip: u32, number: u32) -> Result<AdafruitPeristalticDispenser>

Create a new AdafruitPeristalticDispenser which will have pwm control over the pwmchip at number. This function does not export he PwmChip

Arguments:

• chip: u32 - The pwmchip number to provide to AdafruitPeristalticDispenser
• number: u32 - The pwmchip number to provide to AdafruitPeristalticDispenser

Returns:

• An error if setting the PWM chip is not found or AdafruitPeristalticDispenser.
