Java seems to have taken off as the platform and language of choice
for many embedded devices. Would it be feasible for Python(perhaps
running on an embedded version of Linux) to act in such a capacity.
Most of my experience with Python has been with Unix-type scripting
tasks and using it when it is an applications built in scripting, but
I know some people try to use to build larger complex applications. Is
the Python interpreter portable...

C is inadequate for embedded systems for the following reasons:
1) Direct addressing of memory mapped I/O is not supported simply
and easily. You have to find work-arounds that are compiler dependent.
You have to create macros , use casting and use indirect addressing
(pointers) to read or write to memory mapped I/O.
2) C does not support real time interrupts. The interrupt
vectoring is compiler dependent.

Are there any restrictions/problems for use of C++ STL in development
in embedded systems?
In particular:
* Does STL require too much space/memory?
* Is 'implementation of STL algorithms/methods' reenterable/reentrant?
* What is the cost to provide continuity of vectors in memory?
Any other problems?

The memory allocation issue in embedded systems is usually critical..
How can one manage that?
1. Via 'new'
char* p = new (nothrow) char ;
if (p == 0)
{
// He we know that it is impossible to allocate the requested memory
// We can do something relevant.

Is there a Python packaging that is specifically for
embedded systems? ie, very small and configurable so the
user gets to select what modules to install?
For Linux-based embedded systems in particular?
I'm thinking of running it on the Linksys's Linux-based open
source router WRT54G. It has 4MB flash and 16MB RAM. I think
another model has 16MB flash. Any possibilities of running
Python on these systems?

When I want to store a number, I use "unsigned". I go with unsigned
because it's the natural type for the system, and so should be the
fastest.
However, there are 8-Bit microcontrollers out there that do 8-Bit
arithmetic faster than 16-Bit arithmetic, and so on these systems char
is faster than int.
Standarising C in such a way that int is at least 16-Bit, has this
made C both slow and memory-hungry for embedded systems programming?

There are a few guarantees I exploit in the C Standard. For instance,
I might write
(unsigned)-1
to get the maximum value for an unsigned integer.
Also, I might rely on things such as:
memset(data,-1,sizeof data)

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules.
He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms.
