Programming :: Build A Spi Program Using C++?
Jan 19, 2011
I'm trying to build a spi program using c++. I'm able to perform half-duplex transfers using the read/write functions, it works perfectly. Now I need to perform a full-duplex transfer, but I'm facing some problems. When I try to receive more than one byte, the slave returns to me only one byte.Ex: I send: FF FF FF FF FF The slave must return: 03 02 00 13 04 But what is happening is:
1st Transfer:
tx: FF FF FF FF FF
rx: 03 00 00 00 00
2nd Transfer:
tx: FF FF FF FF FF
rx: 02 00 00 00 00

im trying to build a simple program for my C programming class, this is the source code
#include <stdio.h>
int main()
{
int length, width, length, height, area, perimeter;
perimeter = width + length + height;
area = width * length + heigth;
[Code]...
i dont see any error (you might)but every time i run it it runs but after it asks me to input for the width i do it but it doesn't take me to the length, it just stays blank until i input another value in the same place for the width, it asks me for 4 inputs in total i don;t know why, and after i run it different times it gives me different values for the perimeter and are. how can I fix this?

I am new to the whole concept of makefiles, and I'm trying to compile and build my program using a makefile template I have found. My project consists of three directories: "source", where my .cpp files are (source1.cpp, source2.cpp, source3.cpp), "include", where my .h files are (header1.h, header2.h, header3.h), and "obj", where the object files are to be stored (obj1.o, obj2.o, obj3.o). In the project root directory is my makefile, which is as follows:
Code:
EXEC = myexe
CC = g++
IDIR = include
SDIR = source
ODIR = obj

I'm trying to build a KDE program from source. I have installed the qt3-devel.i686 package. When I try to configure, I receive this error message
Quote:
checking for KDE... configure: error: in the prefix, you've chosen, are no KDE headers installed. This will fail. use another prefix!
Anyone know how I can build KDE programs in Fedora?

I'd like to build a .deb file which will contain my Perl program. I just want it to be deployed with dpkg -i on debian systems later. So it's just a matter of having the good arborescence in my .deb package. For that purpose, in the debian/rules file, I'm declaring some dh_install lines in the install rule.
My issue is that I know how to achieve my goal, but only with writing a ton of dh_install lines (one line, for one file...)
example :
clean:
dh_testdir
dh_clean
install: build

I have a log file and there are many different types of exception in this file. These could be looked as follow:
Code:
One can see there two types of exceptions: ORGNoCompetenceException and SocketException.
I will filter out the name/type of exception and the number of each type of exception. At last, this statistic data will write to file and create a Excel table.

Android SDK installed using android-sdk_r22.6.2-linux.tgz available from URL...My problem is I can't build the android app. The console in Eclipse tells me something (translated) like this;

i am trying to create an exclude regular expression for my build.xml. The problem is, that i am trying to find some info on which REs are acceptable/valid for ant... Is ant using standard regular expressions? POSIX ones? Since it is a java-based tool, the "Java REs" are probably valid. I am a little bit confused. If somebody can help me out with the different RE standards, i would be most obliged.

I need to create a SW project both for Windows (written with MS Visual Studio 2005) and Linux. Currently I have a build script for windows and another for Linux. I would like to build the project for both platforms on a single PC. Is there a way of building VS2005 projects with Linux (not using Cmake)?

I'm sure this has been covered somewhere before, but I couldn't find anything and so figured I would post here. I have been using Linux OSes for the past couple of years and also using GCC/G++ for application development. However, I have almost always been on x86 systems and never gained much experience using the wide range of optimization options available.
My question is, if I do not specify the -march=PROCTYPE option, will GCC still be able to detect the current architecture and build the code accordingly? I primarily ask this because I am working with an x86_64 system, and specifying -march=x86_64 in my makefiles generates errors about it being an unknown processor type, even though the CPU and OS are X86_64. I know this sounds like a newbie question, but it's just ground I've never had to cover before until now.

I have downloaded whole linux source codes of fedora in a dvd. There are several rpm packages and lots of directories in it. I want to load all source codes to version control system (svn or cvs) which is loacated in a server and develop it step by step .During this time I want to build my own distribution. So I need to know how to build all these packages at once. Is there anyone who can explain "how to do" to me

I am new to using Linux (Debian) and I wanted to install an IDE that covers all languages (C++, Java, SQL) so I decided to try Anjuta, but when I entered a simple "Hello World" code and tried to run it, I noticed that the Build > Compile selection was grayed out. I read on another forum that Anjuta can only compile projects so I switched to Geany, same problem. Do I have to install a compiler?

I'm posting the main build-script and attaching the rest of the scripts in a compressed form. The errors mainly comes from the scripts in "/first_installation/usr/share/siem-live/init"

I've been a PHP developer for about 6 years now - the last two years I have been pretty inactive though. Just recently though, I have been reading resources on all the different programming patterns (Factory, Singleton, Registry, Observer, MVC, etc) to try and get my head around good programming techniques. For myself though I find that I can only truly understand how these methods work when I am forced to do them myself.I have a large project I am doing at my workplace (me only) that involves building a very complex PHP application.
I would like to know your professional opinion; should I spend the extra time to program this PHP application myself and really, properly learn all these different programming patterns? Or, should I just build on top of a PHP framework like the Zend Framework for speed's sake (and flexibility/features)?
I have found understanding exactly how the Zend Framework works hard, just because I haven't been exposed to using these programming patterns myself. I hate that - I want to fully understand exactly what is happening in my application and know exactly how each part relates to others.

I have recently trying to build an Accounts system database for a project. When you run the program it goes in the main menu sort of like this.
Accounts System
Add a Customer With a Contract......1
Add a Customer Without a Contract...2
Display all Customers...............3
Find a Customer.....................4
Edit a Customer.....................5
Print a Statement...................6
Print an Invoice....................7
Load File...........................8
Save and Exit.......................9
When you add a customer with a contract, you add name, address, start contract, end contract, payment and email address. Now, is there a code I could write to get back to this menu. To not confuse anyone, all I just saying is supposing I accidentally push number 1 on the keyboard and suppose I didn't want to add a customer. In other words I need a code that can cancel (or stop) adding a customer to go back to the accounts system menu.

I'm trying to debug a module I programmed but I don't want to do it on the running host but against UML (don't want to reboot every 5 minutes).
The UML kernel I downloaded is 2.6.38.2. I have already downloaded the ubuntu kernel headers for this version (they belong to natty though I'm running maverick.... when I installed the .deb file with dpkg I had no problem at all).
Now I'd like to build said module against these headers. How can I do it?
Here's the makefile for my module code...

I'm trying to use buildroot to cross compile some libraries for me. To do so I've set up build root to point to my working tool chain in the menuconfig.All seems fine however when I try to make (buildroot) I get the following error
rm -rf /root/buildroot-2010.05/output/build/buildroot-config
mkdir -p /root/buildroot-2010.05/output/build
cp -dpRf package/config/buildroot-config /root/buildroot-2010.05/output/build/buildroot-config
Checking external toolchain settings
Incorrect selection of the C library
make: *** [/root/buildroot-2010.05/output/stamps/ext-toolchain-installed] Error 255
I know it's pointing to the correct files and gcc as any wrong paths are reported in make menuconfig.
