FreeRTOS yog ib chav kawm ntawm RTOS uas yog tsim los me me kom khiav ntawm microcontroller - txawm hais tias nws siv tsis txwv rau cov ntawv thov microcontroller. FreeRTOS yog li muab lub sijhawm tseem ceeb ntawm lub sijhawm teem sijhawm ua haujlwm, kev sib txuas lus ua haujlwm, sijhawm thiab synchronization primitives nkaus xwb.

Ib yam li ntawd, qhov sib txawv tseem ceeb ntawm Linux thiab FreeRTOS yog dab tsi?

Ib Qhov sib txawv loj ntawm FreeRTOS thiab RTLinux yog lawv qhov ntau thiab tsawg. FreeRTOS khiav ntawm AVR muaj hneev taw (tus nqi ROM siv) ntawm kwv yees li 4.4 kilobytes. [4] RTLinux ntawm qhov tod tes yog qhov scalable. Cov Linux kernel tuaj yeem raug tshem tawm ntawm kev ua haujlwm uas koj tsis xav tau.

Tom qab, lo lus nug yog, yog FreeRTOS nyuaj lub sijhawm? FreeRTOS yog a tiag - sij hawm operating system kernel rau embedded li uas tau ported rau 35 microcontroller platforms. Nws raug faib raws li MIT License.

Kuj kom paub, txhais li cas los ntawm RTOS?

A real-time operating system ( RTOS ) yog lub operating system (OS) npaj los ua haujlwm rau cov ntawv thov hauv lub sijhawm uas ua cov ntaub ntawv raws li nws los, feem ntau yam tsis muaj kev ncua sijhawm. Cov sijhawm ua haujlwm yuav tsum tau ua (xws li OS ncua sijhawm) yog ntsuas hauv kaum ntawm vib nas this lossis luv luv ntxiv ntawm lub sijhawm.

Vim li cas peb thiaj siv RTOS?

Multitasking, ib leeg, yog vim li cas txaus siv ib RTOS hauv ntau lub tshuab. Nws tso cai rau koj los rhuav tshem cov teeb meem nyuaj rau hauv cov ntawv yooj yim thiab tsom mus rau kev txhim kho ntawm txhua txoj haujlwm es tsis yog teem caij thaum txhua yam khiav. Nws kuj ua rau nws yooj yim dua rau kev faib ua haujlwm ntawm cov tswv cuab ntawm pab pawg. Tus teem sijhawm ua tus so.
