Installation

To install the library, simply run:

pip install inoio

Example

The following snippet demonstrates how to use the library:

import sys
from inoio import InoIO, errors


def main() -> None:
    conn = InoIO(port="/dev/ttyS2", baudrate=9600)

    try:
        conn.connect()
    except errors.InoIOConnectionError:
        sys.exit("Failed to connect")

    conn.write("A foo that bars")
    print(conn.read())

    conn.disconnect()


if __name__ == "__main__":
    main()

Running this small program would return:

Received message: A foo that bars

Assuming the following code is uploaded to the device and the device is running:

void setup()
{
    unsigned int baudrate = 9600;
    ::Serial.begin(baudrate);

    unsigned int timeout_msec = 10;
    ::Serial.setTimeout(timeout_msec);
}

void loop()
{
    while (::Serial.available() > 0)
    {
        ::String message = ::Serial.readString();
        message.trim();

        ::Serial.println("Received message: " + message);
        ::Serial.flush();
    }
}
