WebCMSIS-RTOS is a standarized RTOS abstraction from ARM. You can us it for example with FreeRTOS or Keil RTX. A oversimplified analogy may be POSIX - you can basically compile the same code on Linux, BSD and MacOS. A good use case can be migration. If you eventually want to migrate (on ARM CPUs) from FreeRTOS to a different RTOS, then … WebDescription. Initialize and start the SysTick timer. The System Tick Time (SysTick) generates interrupt requests on a regular basis. This allows an OS to carry out context …

I have … WebThe CMSIS-RTOS RTX functions provide delays in units of milliseconds that are derived from the RTX Timer Tick. It is therefore recommended to configure the RTX Timer Tick to generate a 1 millisecond interval. Configuring a longer RTX Timer Tick may reduce energy consumption, but has impacts on the granularity of the timeouts. bank hasamitra
