Troubleshooting your own embedded systems can be challenging, and debugging the code can be even more daunting! However, nothing compares to the satisfaction of witnessing your hard work come together and function seamlessly!

While reading a book on reusable firmware design, I came across a pointer declaration, 𝐬𝐭𝐚𝐭𝐢𝐜 𝐮𝐢𝐧𝐭𝟑𝟐_𝐭 𝐯𝐨𝐥𝐚𝐭𝐢𝐥𝐞 * 𝐜𝐨𝐧𝐬𝐭 𝐚𝐫𝐫; which might be straightforward to understand but I still get confused when deciphering these variable declarations. The position of the qualifiers makes it daunting to understand. Hence I made some notes which made me understand these statements better. In general the declaration of a variable talks about four things, * Who can see it? * Is the data allowed to change? * Is the pointer allowed to change? * Do I need optimization? Take a look at the slides to get an understanding of these declarations. Let me know your thoughts on it. Any feedback is welcomed 😁. #C #embeddedsystems #declarations #embeddedC #microcontrollers

Don't Fear Failure, Embrace It: How the Circuit Breaker Pattern Makes You a Software Superhero Feeling the sting of a system meltdown? We've all been there. But what if failures could be your secret weapon? The Circuit Breaker Pattern is like a superhero's forcefield for your software systems. ️ It gracefully handles external service hiccups, preventing cascading failures and keeping your system up and running. Here's the gist: Your system acts like a hero, confidently making requests. A failing service throws a punch (aka errors). The Circuit Breaker trips, blocking further punches and protecting your system. ✋ After a timeout, it cautiously peeks out (half-open state) to see if the service has recovered. Success? Back to normal operation! Failure? Back to blocking mode until things stabilize. ️ The Benefits are Super, Too: Improved System Resilience: Isolate failures and prevent domino effects. Reduced Load on External Services: Don't overload them when they're down for the count. Faster Recovery: Automatic retries get you back in the game quicker. ️ Improved Monitoring: Gain valuable insights into external dependencies. Ready to Level Up Your Software Skills? The Circuit Breaker Pattern is a powerful tool for building robust and resilient systems. Learn how to implement it and become a software development hero! #softwaredevelopment #resilience #circuitbreaker #engineering #developerlife Let's discuss in the comments! Have you used the Circuit Breaker Pattern? What are your experiences?

Thread.sleep(15); If you coded the equivalent of the above into your firmware, you likely just created a bug.

Updating the MCU-Link and MCU-Link debug probes is now easier and simpler: no need to set a jumper. https://lnkd.in/eQHprqnv

Interested in using QP for your next firmware project? If so, one of the decisions that your team must make is which kernel will you pair with the framework. In my new guest video at Quantum Leaps, I provide five tips to help your team successfully use the QP framework. Tip 4 focuses on kernel selection. Take a look at the link below, which takes you directly to the portion on selecting a kernel to pair with QP. https://lnkd.in/ehA3zs9g

Question: Is a bootloader required for every microcontroller project, and in what situations is a bootloader necessary or not? Answer: No, a bootloader is not always required. A bootloader should be used in the following situations: Firmware Updates: When updates need to be applied via external storage. Configuration Management: To load settings from non-volatile memory. Security Enhancement: To verify software signatures for integrity. Additional Functions: Such as debugging or handling multiple storage media. A bootloader may be unnecessary in the following cases: Static Applications: Where no post-deployment updates are needed. Resource-Limited Systems: Where minimizing resource usage is critical. Controlled Environments: Where no frequent updates are required. Applications Not Requiring Advanced Security
