Or I'm using only the thread-safe FreeRTOS heap memory allocation which exist for many good reasons. Things get problematic if malloc() still is pulled in, either because it is used by a middleware (e.g. TCP/IP stack) or if using C++. Dave Nadler posted a. FreeRTOS implements multiple threads by having the host program call a thread tick method at regular short intervals. The thread tick method switches tasks depending on priority and a round-robin scheduling scheme. The usual interval is 1/1000 of a second to 1/100 of a second, via an interrupt from a hardware timer, but. Just a general resource question. The Softdevice uses RTC0, FreeRTOS (by coded default) uses RTC1. So in order for the SDK ble_conn_params.c to run properly I have to link app_timer_freertos.c to the Makefile. This leaves RTC2 available for general nrf_drv_rtc usage. Is this an acceptable setup? I seem to be having. My company is planning to use freeRTOS for one of their commercial product. I just wanted to know if we can directly take the freeRTOS source and use it, will it be a problem in commercial products (from which the company will make money).
