I am working on a project and need a bit of help here and there. I am working on it with someone who knows a lot more than I do but he is available only 1 day a week, so instead of posting questions on various forums (mostly never answered) I am considering looking for someone who can work on a retainer of X per year or something like that and would be able to provide support. It ranges ...

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


Static analysis tool?

Perhaps someone here can help... I'm doing a presentation on techniques for embedded, especially removing and keeping out bugs ;-) Using an example project from last year. A reviewer of my first draft suggested many of the bugs surfaced in the project would have been caught by static analysis - but I haven't had such great luck in the past. Tried CPPcheck, and while it found some les...


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 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...


Linux embedded and direction control of RS485 transceiver

I have an half-duplex RS485 bus with 10-20 different nodes. Some of them are 8-bit MCU based, one of them could be Linux embedded. It's half-duplex, so it's important for the transmitter node to disable the driver as soon as the last transmitted bit is shifted out. Many small low-cost MCU has interrupt on transmission complete, so the delay of disabling the driver is usually on the ord...

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.
