rtos

问题 It sounds reasonable that the os/rtos would schedule an "Idle task". In that case, wouldn't it be power consuming? (it sounds reasonable that the idle task will execute: while (true) {} ) 回答1: This depends on the OS and the CPU architecture. On x86 (Intel compatible) the operating system might execute HLT instructions, making the CPU wait until something interesting happens, such as a hardware interrupt. This supposedly consumes very little power. Operating systems report the time spent doing

问题 i am attempting to integrate freeRTOS to my application that run on AT32UC3A0512. I downloaded a freeRTOS project example for EVK1100 (it Supports the AT32UC3A) and try to include the kernel source file so my application hierarchy looks like : src |ASF |APP_FOLDER |freertos |freertos-7.0.0 this hierarchy is different than the the hierarchy provided in the freeRTOS project example which looks like src |ASF |thirdparty |freertos |freertos-7.0.0 /********** freertos-7.0.0 is under ASF***********

问题 what does mean x and v in task creating or managing of free RTOS? xTaskcreate or vTaskcreate? 回答1: The leading character(s) of the FreeRTOS functions identify the return type of the function. Functions that start with "v" return void. Functions that start with "x" typically return a result code or handle. See the Naming Conventions page of the FreeRTOS coding standard. 回答2: Acording to FreeRTOS Documentation: Variables of non stdint types are prefixed x . Examples include BaseType_t and

问题 I want to make an RTOS for 8051 and very confused as what minimum requirements should be followed to make an OS in 8051 as 8051 has very limitted resources in case of RAM and ROM. It is just and assignment type problem but i am really confused as we make softwares for 8051 are they not an OS? which features differenciate a normal regular coding of micro controller from RTOS? please help thanks 回答1: An typical RTOS provides at least the following: Deterministic task scheduling Task

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . There are many different RTOS available for microcontrollers. I am specifically looking for RTOS that support the ARM Cortex M processors. Also, I am not interested in closed source solutions.
