This article introduces the relevant knowledge of "What is the difference between FreeRTOS and uCos". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

What freeRTOS does better than uCOS II:

Kernel ROM and RAM consumption are smaller than uCOS, especially RAM. This is a scarce resource in the MCU, uCOS at least 5K above, and freeOS with 2~3K can also run very well.

2。FreeRTOS can use Co-routines to reduce RAM consumption (shared STACK). uCOS can only be used with TASK (each task has a separate STACK).

FreeRTOS can have tasks with the same priority, which are processed in turn by time slice, and uCOSII has only one unique priority for each task. So, in theory, freeRTOS can manage more than 64 tasks, whereas uCOS can manage only 64.

FreeRTOS is a free commercial application. Commercial use of uCOS requires payment.

FreeRTOS is not as good as uCOS:

1. Simpler than uSOS, inter-task communication freeRTOS only supports Queque, Semaphores, Mutex. uCOS also supports Flag, MailBox.

uCOS has more support than freeRTOS. In addition to the operating system, freeRTOS only supports TCPIP, uCOS has a lot of extension support, such as FS, USB, GUI, CAN and so on

3. uCOS is more reliable and resistant to optimization. FreeRTOS will have problems when I set it to medium optimization.

What is the difference between FreeRTOS and uCos? Thank you for reading. If you want to know more about industry-related knowledge, you can pay attention to the website. Xiaobian will output more high-quality practical articles for everyone!
