How much footprint does C++ exception handling add
This issue is important especially for embedded development. Exception handling adds some footprint to generated binary output. On the other hand, without exceptions the errors need to be handled some other way, which requires additional code, which eventually also increases binary size. I'm interested in your experiences, especially: ...
(avr-gcc) Makefile support for sub-directories
Hi; I am working on an AVR project and have multiple folders containing my code. The makefile I am using is the "Standardized AVR Makefile Template" by Pat Deegan. It's capable of compiling every cpp file in every folder correctly and generate the right object (.o) files. However, the linker fails because it try to find to .o files i...

How do I do source level debug of library
I have a following setup. Although my working setup deals with ARM compiler Real View Developer Suite (RVDS) 3.2 on a Windows host, the situation could be generic for any other C compiler on any host. I build a ARM library (static library - .a file) of C code using RVDS 3.2 compiler toolchain on Windows host. Then I link this library w...
C++ or C# to program mobile barcode device?
I will be developing some applications using mobile barcode scanners and need to choose between C++ and C# for coding on the scanners. I am considering Intermec's CK31 or similar for the combination of wifi, scanning choices, programmability and user interface options. It runs Windows CE .NET 4.2 according to their spec sheet. Intermec...
How to transition from embedded software development to web development?
Hello, I am an embedded software developer with about 5+ years of experience working on mobile devices. I recently lost my job and most of the jobs in the embedded field (that I came across) require security clearance and I am not eligible for that. So, for this reason and also just to learn something new, I am planning to move to web d...

How to perform regression tests in embedded systems
What good practices and strategies are there for running regression tests in embedded environments or in other situations where the possibility to automate tests is very limited. In my experience a lot of the testing has to be performed manually i.e. a tester needs to push a sequence of buttons and verify that the machine behaves correc...
indicating libgloss machine when building newlib for bespoke platform
I'm compiling newlib for a bespoke PowerPC platform with no OS. Reading information on the net I realise I need to implement stub functions in a <newplatform> subdirectory of libgloss. My confusion is to how this is going to be picked up when I compile newlib. Is it the last part of the --target argument to configure e.g. powerpc-ibm-<n...

How do I mark code with side effects?
I'm working on a project on an 8051 where every byte counts. As such, I am using some global variables where I normally wouldn't. The normal method of passing pointers into a function adds too much overhead here. I have a number of functions that use single bit variables (a compiler specific extension to C) to signal the outcome of a ...

Why is XST optimizing away my registers and how do I stop it?
I have a simple verilog program that increments a 32 bit counter, converts the number to an ASCII string using $sformat and then pushes the string to the host machine 1 byte at a time using an FTDI FT245RL. Unfortunately Xilinx XST keeps optimizing away the string register vector. I've tried mucking around with various initialization...
