Introduction Debugging embedded software is one of my least favorite activities, but unfortunately, it is necessary. Fortunately, advancements in technology and toolchains have generated a wealth of new techniques that significantly accelerate the debugging process. Let’s take a look at some of these methods, from traditional breakpoint debugging to more advanced instrumentation tracing techniques. Tip … Read more
Today, Pi Zi Heng will share with you the three implementations of critical section protection in Cortex-M bare metal. Those who have worked with embedded systems and RTOS are likely familiar with the function codes OS_ENTER_CRITICAL() and OS_EXIT_CRITICAL(). In RTOS, multi-tasking (process) handling often occurs, and in some situations, certain special operations (such as Flash … Read more

When developing projects based on RTOS, we often encounter mutual exclusion situations, such as: multiple tasks needing to use a single UART port to send data. If mutex locks are not used, a higher priority task may preempt the UART and send data, potentially resulting in “garbled” data being sent. Today, we will discuss a … Read more
