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.

Test hardware

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

Example

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

use jsy_mk_194::*;

struct MyUartImpl {
    // Some necessary fields
}

impl Uart for MyUartImpl {

    fn read(&mut self, buf: &mut [u8], _timeout: u32) -> Result<usize, error::UartError> {
        // Do something
    }

    fn write(&mut self, bytes: &[u8]) -> Result<usize, error::UartError> {
        // Do something
    }
}

struct MyDelayImpl {
    // Some necessary fields
}

impl DelayMs<u16> for MyDelayImpl {
    fn delay_ms(&mut self, _ms: u16) {
        // Do something
    }
}

Then, you need call read() method:

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!
