I was wondering if there are going to be any updates to the FreeRTOS book. I bought it but was disappointed to find that it’s missing parts of the API. Now, some of these are new features (e.g. event groups), so that’s understandable. But there’s no mention of timers or heap_4.c. Some things that are mentioned are missing descriptions of API calls (e.g. xSemaphoreCreateRecursiveMutex). Also, it would be useful if the PDF file had a document version number, and it mentioned which version of FreeRTOS that it corresponded to. Thanks very much for for FreeRTOS! Graham

The book is in the process of being updated, but I can’t say when the update will be available. It is very laborious (especially creating/maintaining the example projects), and in the mix with lots of other development work going on simultaneously. The updates will be additions to cover the new features, rather than changes to existing content (other than editing), so the current text still covers the fundamentals of how to use the kernel and so still provides an excellent tutorial, especially for beginners. The reference manual has already been updated to V8. Regards.
