# Rust crate for JSY-MK-194

## What is JSY-MK-194?

JSY-MK-194 is hardware to get some informations about current, voltage, frequency of AC current.

You found this hardware easly on some chiness website.

![JSY-MK-194](doc/jsy-mk-194.jpg)

## Test hardware

This crate has only tested on ESP32-WROOM-32 microcontroler.

## Example

First, you need provide implementation of some trait (hardware abstract):

```rust

use jsy_mk_194::*;

struct MyUartImpl {

    // Some necessary fields

}

impl Uart for MyUartImpl {

    fn read(&mut self, buf: &mut [u8], _timeout: u32) -> Result {

        // Do something

    }

    fn write(&mut self, bytes: &[u8]) -> Result {

        // Do something

    }

}

struct MyDelayImpl {

    // Some necessary fields

}

impl DelayMs for MyDelayImpl {

    fn delay_ms(&mut self, _ms: u16) {

        // Do something

    }

}

```

Then, you need call `read()` method:

```rust

let mut jsy_my_194 = jsy_my_194::new(my_uart_impl, my_delay_impl);

let _ = jsy_my_194.read();

print!("First channel power: {}", jsy_my_194.channel1.power());

```

That's all!

## Changelog

### 1.0.3

- Allow update UART after change bitrate

### 1.0.2

DON'T USE IT. IT'S MISTAKE

### 1.0.1

- Rewrite module to be more easy to understand

- Add new public `read_with_timeout` method to allow user set his timeout
