embedded-hal-mock

This is a collection of types that implement the embedded-hal traits.

The implementations never access real hardware. Instead, the hardware is mocked or no-op implementations are used.

The goal of the crate is to be able to test drivers in CI without having access to hardware.

Status

• [x] Simple I2C implementation
• [x] No-op Delay implementation

no_std

Currently this crate is not no_std. If you think this is important, let me know.

Usage

I2C

```rust use embeddedhal::blocking::i2c::Read; use embeddedhal_mock::I2cMock;

let mut i2c = I2cMock::new();

// Reading let mut buf = [0; 3]; i2c.setreaddata(&[1, 2]); i2c.read(0, &mut buf).unwrap(); asserteq!(buf, [1, 2, 0]); asserteq!(i2c.getlastaddress(), Some(0));

// Writing let buf = [1, 2, 4]; i2c.write(42, &buf).unwrap(); asserteq!(i2c.getlastaddress(), Some(42)); asserteq!(i2c.getwritedata(), &[1, 2, 4]); ```

Delay

Just create an instance of embedded_hal_mock::DelayMockNoop. There will be no actual delay. This is useful for fast tests, where you don't actually need to wait for the hardware.
