Real Time Engineers Ltd. launched version 7.0 of FreeRTOS, which is a free real time MCU operating system. The latest version of the open source embedded RTOS includes a new software timer implementation. The timer enables callbacks to be executed in a task context (instead of interrupt context). It does not consume any processing time or generate any run time overhead unless a timer has actually expired. FreeRTOS v7.0 is backward compatible with FreeRTOS V6.x.x.
