So, this is the third time in a month or so that I've needed to tell someone "use a task loop" -- but I'm not sure if I can say "just Google it". So: When I say "task loop" I mean that I'm _not_ using an RTOS, but rather that I'm doing some small thing in a small processor, and somewhere in my code there's a loop that goes: for (;;) { if (task_1_ready) { task_1_...

Hi all, I am new to this group but checking over recent postings seems to indicate a fair amount of Clue kicking around [1]. A bit of background before y'all tell me to RTFM or JFGI. I've got quite a lot of experience in programming 8 bit microcontrollers with assembler; I've also done quite a lot of 32 bit embedded stuff using an RTOS with C. What's new to me is using a 16 bit mid-ra...

I'm working with a very old 68360 based embedded system running from flash ROM based on pSOS+ RTOS, and need to debug. The BDM cannot do hardware breakpoints while running from ROM and thus I'm looking for an emulator that may work with this. I've tried an old Mikrotek power-pack, but it's DOA upon boot, and am looking at what anyone may have around they no longer need. I don't have a bud...

I work in software research and developement in the aerospace industry. We're assisting a project where they are interested in looking at web services in an embedded system. This would most likely be WSDL/XML/SOAP. While there would be fairly powerful processing to an extent, it's still a resource-constrained environment, running on an RTOS (I think VxWorks). In particular they are concer...
