The invisible RTOS continued

Posted by Colin Walls

Colin Walls Last week I wrote about a test harness for applications using an RTOS. The idea was to have a library of functions corresponding to the API calls of a particular RTOS. Specific tasks of an application, that are under test, would be linked to this library to enable the code to be executed on a desktop computer in a useful way. I had some feedback on this posting from a couple of people, talking about … Read More

It took me a while before I could fully understand what they were after, but it did become clear eventually. They were considering an environment where a number of engineers were working on an embedded application [using Nucleus]. Each guy was developing

In this case, it was a suggestion for a topic to address, which was particularly welcome. The writer wanted me to talk about blocking and non-blocking APIs … At the heart of a real time operating system [RTOS] is the kernel, which is comprised of the task scheduler … Read More
