rDuino-Compiler-Uploader-Server##

Description

This small web server (a webapp), intented to run locally, that will receives a piece of Arduino code on port 5005, compile it and upload the binary to the target. This server has been developed to close the gap between Blockly@rduino and the real Arduino target, when CodeBender.cc is not available or can not be used.

Install on Linux

sudo pip install Flask
chmod +x rDuino_uploader_server.py

You also need to add the current user to the group that allow /dev/ttySUBxx access. This group is generaly 'dialout' or 'uucp'. To check the appropriate groupname, try:

ls -l /dev/ttyUSB*

Use:

sudo usermod -a -G dialout $USER

Or:

sudo usermod -a -G uucp $USER
sudo usermod -a -G plugdev $USER

Don't forget to restart the session after adding the user to the group.

If you still have problems with priviledges to access to the USB port, the best is to add a rule by doing the following:

sudo nano /etc/udev/rules.d/50-myusb.rules

Copy this text and save the file:

KERNEL=="ttyUSB[0-9]*",MODE="0666"
KERNEL=="ttyACM[0-9]*",MODE="0666"

Unplug and replug the device to apply these rules.

Usage

Run the server on the local machine, using python, by entering the following commands in a terminal window.

./rDuino_uploader_server.py

or python rDuino_uploader_server.py

Leave the terminal open, so the server will run all the way along.

Design your application in Blockly@reduino. Connect the Arduino target. Go to the 127.0.0.1:5005 webpage and select the USB port on which your Arduino target is connected, and the appropriate Arduino board type. Go back Blockly@reduino and click on the button: "Local upload in Arduino"

At this time, an HTTP request with the code is sent to http://127.0.0.1:5005/ along qith the code to be compiled.

The server get the code, prepare a shell command, and run it in order to have the code compiled, linked and uploaded to the target.

If no error is found, your code is uploaded in the Arduino target. You can get the results by looking at the page at http://127.0.0.1:5005/ The bottom of this page is periodically refreshed.
