TockOS is an embedded operating system designed specifically for running multiple concurrent, mutually distrustful applications. It is optimized for embedded platforms based on Cortex-M and RISC-V. The core of its design is a protection mechanism that guards against potential malicious applications and isolates device drivers. TockOS employs two mechanisms to protect different components of the … Read more
Choosing a suitable embedded operating system can consider the following factors: The first is the application. If the embedded device you want to develop is closely related to network applications or is a network device, then you should choose embedded Linux or uCLinux, rather than uC/OS-II. The second is real-time performance. There is no absolute … Read more

This article introduces a precise delay method in the Cortex-M kernel. Introduction Why learn this delay method? Many times when we run an operating system, we generally occupy a hardware timer – SysTick, and the clock tick of our operating system is generally set to 100-1000HZ, which means an interrupt occurs every 1ms – 10ms. … Read more
