Integrated software and RTOS
With IAR Embedded Workbench, you have access to a wide selection of pre-integrated software solutions from leading RTOS and middleware vendors.
The C-SPY RTOS Awareness plugin modules give you a high level of control and visibility over an application built on top of a real-time operating system. It displays RTOS-specific items like task lists, queues, semaphores, mailboxes and various RTOS system variables.
Task-specific breakpoints and task-specific stepping make it easier to debug tasks. Ready-made example projects are available for a large number of devices and development boards.
Notice that not all versions and architectures of IAR Embedded Workbench are supported. Please reach out directly to our RTOS partners in case you are missing a specific IAR port for the desired architecture.
