oseppBlock

https://osepp.com/oseppblock-ide
A graphical block system to demystify coding concepts based on the Arduino platform

Using a precompiled version

Download the corresponding version of your system and unzip it
run the oseppBlock program in the directory
For linux system,make sure you have sufficient permissions on the folder and confirm that there is serial port permission
or run sudo gpasswd --add ${USER} dialout.
ubuntu19.xx maybe also need to run
echo 'SUBSYSTEMS=="usb-serial", TAG+="uaccess"' | sudo tee /etc/udev/rules.d/01-ttyusb.rules && sudo udevadm control --reload
and then Re-plug the Arduino board.
For windows, do not put files on the c drive, or the system directory such as desktop
If you are using network discovery(for OTA)
linux needs package sudo apt-get -y install libavahi-compat-libdnssd-dev
windows needs to install Bonjour
(most systems are pre-installed)
Execute the install.sh script(included in the archive) on the Linux system to create the desktop icon and .obp file association:
chmod +x install.sh && ./install.sh.
Uninstall by ./install -u.

Rebuild oseppBlock

install Dependencies

Go to url: https://nodejs.org and follow the instructions to install nodejs
java
python2
for windows,execute npm install --global --production windows-build-tools
It will automatically install msBuildTools and python2.7 (if they are not installed on your system)

Get `oseppBlock` source code

        sudo apt-get update&&sudo apt-get -y install git #only need on linux
        cd $HOME
        #for windows , you need to download and install git first
        #then execute the following command in the bash environment
        git clone --depth 1 git://github.com/DIYOSEPP/oseppBlock.git
        cd oseppBlock
        git checkout master
        cd app/

build

        npm install
        #Specify python2 path in build.js
        node build.js #rebuild scratch and copy file
        npx electron-rebuild -f #rebulid nodejs modules for electron
        npx electron . #try to run oseppBlock

You should see oseppBlock already running

Repackaged

        #linux windows
        npx electron-packager . --overwrite --asar --icon=media/osepp.ico  --prune=true --out=../release-builds
        #mac os
        npx electron-packager . --overwrite --asar --icon=media/osepp.icns --prune=true --out=../release-builds

Packaged files will be stored in ../release-builds

Compile/upload to Arduino board

When you use oseppBlock to compile and upload the program you designed, it will ask you the path of Arduino, make sure the Arduino IDE version you choose is 1.8.9

oseppBlock requires network permissions to detect the Arduino in the LAN (via mdns protocol). Without this permission, oseppBlock will not automatically detect the Arduino IP address, but you can still manually fill in the IP address to use the OTA and serial bridge functions The serial bridge function depends on another project, please refer to: https://github.com/DIYOSEPP/EspUnoWiFi

change log

20201023
- Use mdns-js library instead of mdns, so that libavahi is no longer dependent.
- Separate scratch and app, now they are two parallel projects
- Update electron version
- Add google-closure-compiler and google-closure-library, now scratch will be compiled locally
20200104
1. Built-in arduino-builder (because the arduino-builder included with arduino 1.8.10 IDE is not executable.)
2. No longer necessary to link to the arduino IDE, so send code to the arduino has been canceled and modified to download the INO file.
3. Added screenshot function to save Blocks as PNG files.
4. Add some blocks and modify some blocks(from directly generating code to using libraries).So the Arduino IDE needs to install the oseppRobot library to compile the INO file downloaded from oseppBlock.
20190410
1. Add Chinese support,Usually the display language is the system language,can be specified by adding locale = [en | zh-cn] on the command line.
2. Add jquery ui, separate serial port message and IDE prompt information
3. add line sensor Block
20180704
1. add negative Block
2. change comment Text Font Size
20180626
1. Updated to the latest scratch block core
2. Update to the latest electron
3. add robot blocks and remote blocks
4. add tcp Serial Monitor
5. When the port is an IP address, use arduino OTA to upload the sketch (compatible with Arduino Uno Wifi)

note: Cross build for ia32

        apt-get install gcc-multilib g++-multilib
        npx electron-rebuild -f -a ia32
        npx electron-packager . --overwrite --asar --icon=media/osepp.ico  --prune=true --out=../release-builds --arch=ia32
