Re: [Pharo-users] UDP example

by Annick Fron

Thank you but your explanation does not explain what is the type (signed unsigned) and the size of each header component. Thus it is impossible to work with that.

Beautiful! Great work. It is a lot of work to do a project inside such a big bank, let alone make a success of it. Congratulation to Tomas and the rest of his team. Sven

Do you know if > Linux+Pratch+Arduino is a working team? > I am sure that phratch+Arduino does not work well. Then about Linux, I think it is not a problem. I added JosÃ© Manuel Ruiz in cc. He asked me if I can make Arduino work on Phratch and we have some problems. First of all, I am using the Firmata firmware. There is a bridge between Squeak and Firmata that I took and adapt on Pharo. I can take some values from analog port, but not digital. Now I have 2 problems: - I have not enough knowledge about Arduino to understand what is wrong: Phratch only use the API, and I am not sure the API works well. - For now, I am using the Firmata firmware but we could use the s4a firmware (http://s4a.cat/) We have to test. So, Hilaire, if you have some times to test the two firmware or if you are using one on Pharo, or if you have any knowledge to share. It will be really fast to make something work. Thank you again for yoour feedback and Ihope you can help me for Arduino.

Hi Hilaire, Which version of Linux are you using ? Thank you again for your feedback. Here is my comments for your list: - On Linux, keypad does not work >>> Ok, the last build of the vm I use is from 5 month ! I redo it, it should work today. By the way, keypad does not work on pharo-launcher too. - for me, the font characters in the bricks are too small >> you can change it in settings. Then in settings Phratch click on the button launch to refresh the display. - the robot, has a non transparent white background, I tried to edit it but the sprite I have is of too low resolution to make something clean >>> I don't understand. I have a transparent background. But I saw a bug: When I edit it, the background become white. I fixed it. - some tools in the paint dialogue are mostly invisible (see screenshot) >>> Yes, they is a strange behavior here. Sometimes it works, sometimes there is this crappy green color... I tried again to fix it. We will see what happen. The point is to clean all this part of Phratch, If there are volunteers :) - preview and loading of JPG background does not work (see screenshot fileDialog) On my Ubuntu 14.04 it works fine. - the file dialog dropdown list arrow is shifted vertically (see screenshot fileDialog) >>>fixed - in the file dialogue to load a previously saved project, the author nor description are displayed (screenshot filedialog project). >>> I open a bug entry. It will be fixed in next version. - I load the the Arduino add-on, I have a new Arduino category but no brick. I will answer in another mail. All these changes are currently building. It will be available today, or tomorrow.

[ANN] JNIPort documentation moves to new web site

by Joachim Geidel

Dear all, so far, the documentation of JNIPort, the Smalltalk library for calling Java code from Smalltalk, has been hosted on a wiki at http://jniport.wikispaces.com. Unfortunately, Wikispaces has decided to stop their offer to host free wikis unless they meet their definition of âeducationalâ. This means that the JNIPort wiki at Wikispaces will be deleted soon, but not before Nov 14, 2014. Therefore, I have moved the contents of the wiki to a new location: https://sites.google.com/site/jniport/ Please update your bookmarks. I will update the links in package comments and documentation as soon as possible, and upload new versions of JNIPort to the Cincom Public Store Repository and SmalltalkHub. This will probably happen when both Pharo 4 and VisualWorks 8.0 Non-Commercial have been released, and the upcoming version 3.0 of JNIPort is compatible with both of them.
