Macro esp_ward::init_i2c_custom

macro_rules! init_i2c_custom {
    ($peripherals:ident, $clocks:ident, $sda_pin:expr, $scl_pin:expr, $freq:expr) => { ... };
}

Initializes a custom I2C configuration, allowing for arbitrary SDA and SCL pins and frequency.

Arguments

• $peripherals: The peripherals instance taken from the board.
• $clocks: The system clocks initialized beforehand.
• $sda_pin: The pin to use for SDA.
• $scl_pin: The pin to use for SCL.
• $freq: The frequency for I2C communication.

Examples

let peripherals = esp_ward::take_periph!();
let system = esp_ward::take_system!(peripherals);
let (clocks, pins) = esp_ward::init_chip!(peripherals, system);
let mut i2c =
    esp_ward::init_i2c_custom!(peripherals, &clocks, pins.gpio21, pins.gpio22, 100u32.kHz());
