Digital write ⏪ ​

This action changes changes the signal of a digital I/O pin to either LOW or HIGH.

Interface ​

(func chip_digital_write (param $pin i32) (param $value i32))

function digitalWrite(pin: i32, value: PinVoltage): void

fn digital_write(pin: u32, value: PinVoltage)

Parameters ​

WebAssembly ​

• pin: must be a valid I/O pin number of the microcontroller
• value: either 0 (low) or 1 (high)

AssemblyScript ​

enum PinVoltage {
    /** Low voltage on a digital I/O pin */
    LOW  = 0,
    /** High voltage on a digital I/O pin */
    HIGH = 1,
}

Rust ​

enum PinVoltage {
    /** Low voltage on a digital I/O pin */
    LOW  = 0,
    /** High voltage on a digital I/O pin */
    HIGH = 1,
}
