new behavior of remoteio: simultaneous processing of remote pins

When remoteio proceeds 2 pins, the second pin must wait until the first one has made his work on the server. This may take time, if the first pin has a long timer and the second pin cannot start its work. A pin blocks itself in the same way. In this modification of remoteio, different pins can work simultaneously. If a pin has two tasks and the second one is asked to start before the first one has finished, the second one interrupts the first one. The main modifications are the use of

1. a list of maps, that allows sending of tasks of several pins to the server
2. an own thread for each pin for treating
3. thread safe queues for each pin as input to the pin-specific threads
4. a thread.Timer in handle_timer instead of time.sleep in order to make the interruption of a task with a time_ms>0 possible
5. the getattr function to find led-funtions only by knowing the name of the function

Further, the internal pin numbering is 'b', by the aid of a conversion dictionary. This allows to suppress the establishing of the sam pin two times by different representations by 'b' and 'g' The syntax to operate the pins is the same as that of remoteio.

Server (remote Raspberry Pi)

Use this all-in-one command to install remoteio as deamon on port 8509. The server can be updated with this command.

bash -c "$(wget -qLO - https://github.com/schech1/remoteio/raw/master/install.sh)"

Using pip

pip install remoteio

When you want to create the server by yourself, you can install the library via pip and use the examples below, for server- and client usage.

Server usage

Start a remote server on port 1234. If no port is specified default port 8509 will be used

from remoteio import run_server

if __name__ == "__main__":
    run_server(port=1234)

Client usage

from remoteio import RemoteServer

if __name__ == "__main__":
    server_ip = "192.168.1.38"
    server_port = 1234

    remote_server = RemoteServer(server_ip, server_port)
    remote_pin = remote_server.pin(7, 'b')
    remote_pin.on(time_ms=2000) # (Optional) Time until switch off
    remote_pin.blink() # Blink LED
    remote_pin.pulse() # Pulse LED
    remote_pin.off()
    remote_server.close()

Use Board numbering

remote_pin = remote_server.pin(7, 'b') # Use physical board numbering

Use GPIO numbering

remote_pin = remote_server.pin(4, 'g') # Use GPIO numbering (e.g. GPIO4)
