Ubuntu :: Make A Program Output To Serial?
Nov 29, 2010I've made a LED gadget, which can light up LED patterns. It connects to serial port with RS232 protocol and receives messages which contain desired patterns. My friend wrote a python program which generates patterns and writes them to terminal. Everything is fine this far. I've made a bash script to run this program:
#!/bin/bash
python gen.py
and set it to autostart with:
chmod 755 scr.sh
mv scr.sh /etc/init.d/scr.sh
sudo update-rc.d scr.sh defaults
What I don't understand is - how do I redirect it's output to ttyS0 so that my device could catch generated data?
I've heard that in Linux every data stream can be redirected anywhere with '>>' in bash script. How do I do that? Can I, dunno, write something like this: python gen.py >> ttyS0 in shell script?

Software :: Match Pid Value In Ps Output To Threads In Program?

General :: Executing PHP File And Read Output To Program
Jun 29, 2011I'm using Ubuntu and I'm programing with eclipse CDT. My goal is to execute a php file and read the output to my c++ program. To do so I thought I should use fork(), dup2() and execl. When in shell, the call "php myscript.php" worked just fine, but when in c++ I tried:
execl("usr/bin/php", "php", "home/geiger/workspace/SemiServer/server_content/myscript.php", NULL);
And it didn't work (the process wasn't terminated and I got no output). I tried different version of this call, like losing the "php" string and/or drop "home/geiger" from the path string, to no better result.

Ubuntu :: Redirecting Output From Printf Statement In C Program
May 22, 2010I've got a C program that I've added some 'printf' statements to monitor a couple of variables. When I run this program manually or from a script, the output is displayed on screen. However, I need to change various variables in the 'test.c' file, run 'make clean' and 'make' a few hundred thousand times. I'm using a script to read the variables in and then using sed to do in-place edits of the file. Unfortunately, with this amount of iteration, it is getting rather tired!
Anyway, I've created a script that is working as long I respond to prompts. I've tried the following to no avail: Code: /path/to/script > /tmp/output /path/to/script > /tmp/output 2>&1 /path/to/script | tee (no output even after adding the -a option) In my C program, I have the following 'printf' statement: Code: printf ("variable1: $s variable2: $s",var1,var2); What am I missing? I've worked with redirection before and it's always worked out fine, but this one plain stumps!
General :: Redirection - Redirect The Output Of A Program To The Diff Command?

Sep 30, 2010I have nine barcode scanners, each of whose input I want to send to a separate instantiation of a program I wrote. Each device shows up as /dev/hidraw_ (I'm using Ubuntu 10.4). The problem is that they all act as simple keyboard input, and I can't seem to redirect the output from one to a specific instance of my program. I've tried something like cat /dev/hidraw5 > ./myapp, and that doesn't work. I've tried actually opening the device in my program using open("/dev/hidraw5"), and it returns success, but subsequent reads don't do anything, and the scanner output is just printed to the console.

View 3 Replies View RelatedUbuntu :: How To Calibrate My Touchscreen
Feb 14, 2010I have an eGalax touchscreen which I installed using the xserver-xorg-input-evtouch package. Now touching the screen makes the mouse pointer move in all sorts of random directions.
What I want, of course, is for the mouse pointer to move to the point where I touched the screen. Typically this is called 'calibration'. Maybe there's a program to run or something, but I can't find it. how do I calibrate my touch screen?
I'm running Jaunty 9.04 so there is no 'System -> Administration -> Calibrate Touchscreen' program.
Ubuntu :: Using A Mouse Instead Of A Touchscreen?
Jun 30, 2011You have probably seen the TV shows and films with the law enforcement agency, or the team at "Leverage" have a large screen with other side screens.
I don't have a holographic display, or even a 60" touchscreen, but I do have a TV, and a couple of computers running 10.10 and 11.04.
What I would like to do, using a mouse instead of a touchscreen, is "push" photos, videos, or dossiers on enemy agents to another screen or phone.
I would imagine it to be something along the lines of hot zones on the desktop, so that if I flick an item to, say, the right of the screen, it will leave my desktop and pop up on the desktop of the (networked, but separate and different) computer to my right, and if I drag / flick an item to the top centre it will Bluetooth it to my phone (which I'll set up to automatically accept any files from "my.desktop.homelan".
I had something a little similar with, I think, Compiz, in that if I flicked an item to the right it would dump it onto virtual desktop 2 (of four horizontal ones).
What search terms would I use in Google or Ubuntu Help to get me started? I can compile, but I'd rather not, as I'm not very good at it, and I can edit .cfg files as long as there are plain English descriptors ("Enable_Feature_Foo=1" "Fave_Place=/home/Me/fave/" etc).
Hardware :: Touchscreen As A Mouse?

Jun 13, 2010I am trying to get my 3M touchscreen to work in Ubuntu. Presently, I have the usbtouchscreen module loaded -- which results in touches being recognized, but the y-axis is backwards (ie: if I press at the top, it shows up at the bottom). Given that hal is depreciated, the only place I could note for configuration options the xorg.conf.d directory. But, I'm unsure what needs to be added there.
Additionally, I am confused over usbtouchscreen vs evdev vs evtouch -- which is supposed to be used at this point?

Ubuntu :: Get USB-Touchscreen From Faytch Running?
Aug 13, 2010since Ubuntu 9.04 I try to get my USB-Touchscreen from Faytch running. With some changes in the setup.sh of the drivers that can be downloaded from faytech.de I finally got it running under 9.04. Changes I made were blacklist path and since no xorg.conf exists anymore I started with a 8.04 Live-CD and copied the xorg.conf from there. not nice but worked. Now with 10.04 new drivers are available but (still only for 8.04). Did the same hack with the xorg.conf (blacklist path was already updated). So the driver and touch stuff works even without any driver whenever I hit the touch screen (anywhere / even in the middle) I always get a mouse click in the top left corner. and that keeps on even after installing the driver.
So without driver I get a click in the upper left corner and with driver installed and calibrated I get a click where I have my finger on the screen (that is what I want) AND a click in the upper left corner (THAT IS WHAT I NOT WANT). I think Ubuntu recognizes the touchscreen as a kind of "unspezified" input device and does a click whenever a touch-event occurs. How can I deactivate that behavior without disabling all the USB??
