What do you think about different languages than usual C for embedded systems? I mean C++, Ada but also Python. Always more powerful embedded processors are coming, so I expect new and modern languages will enter in the embedded world. Hardware are cheaper and more powerful than ever, but software stays expensive. New and modern languages could reduce the software cost, because the...

sci.electronics.design Arm Cortex assembley code Does the Arm Cortex support both the "thumb" 16 bit machine codes and also the 32 bit codes? I had been under the impression that Cortex devices only provided the thumb codes but a little time going through "Arm v7-M Architecture Reference Manual" indicates otherwise. Whether or not that reference manual is suitable for Cortex inform...

I've been refactoring some of my RTOS documentation. Comments from the reviewers suggest there's still some confusion as to terms (despite the fact that I explicitly define them! : < ) All seem to understand the notion of a "thread". And, to a lesser extent, an "application" (this one's a bit harder as there's often no clear-cut distinctions; do you tie it to a "pre-packaged set of algo


Using C preproc to uniquely identify structure members

I could use some advice for a problem that I've had on my mind for years. I'm looking for a black box function that will examine a memory block of a known structure and output a list of IDs that point to any members that have changed. I have a strong feeling that this problem has been solved by many people before me but I've never seen any solution. I'm looking for an elegant solution th...


Multi-master RS485

Are there any *real* implementation of multi-master half-duplex RS485 bus? I often use half-duplex RS485 and I always use a master-slave...

Are there any *real* implementation of multi-master half-duplex RS485 bus? I often use half-duplex RS485 and I always use a master-slave polling protocol. This choice dramatically reduce the complexity of the system and it works well with a limited number of nodes. When the nodes are 10 or 20 and they usually send only a few bytes in a minuted, the polling scheme is inefficient. The bu...

Greetings: Found at a local dump: Huntsville Micro HMI-200-8096 -- Intel 8096 ICE with DIP pod and probes, no software or documentation. Avocet's website is devoid of operating documentation and ftp.hmi.com/ftp.avocet.com now rejects anonymous logins. Any old books, pdfs, old DOS/Win16 Sourcegate s/w, etc. would help a lot! Thanks, Michael msg _at_ cybertheque _dot_ org

I have some 8051 ICE equipment back from my initial employment in the 80s Nohau Emul51 Hardware (2 x Full length ISA cards, pod with some adapters eg DIP40, PLCC44 etc) and software (on floppies, MSDOS-based). Is it of interest to anyone or send it to landfill? -- Cheers Chris.

Static allocation and data hiding

It's a common problem in embedded projects. You want to hide private data of modules, but you don't want to use dynamic memory allocation. In the .h file you write the typedef only and in .c file you write the full definition of the struct. In this way you can't statically allocate the struct, because the compiler doesn't know the inner definition. If you want to use static allocation,...
