🐕 Watchdog timers can reset your MCU before main() 😬 Learn: Why it happens How to disable it safely When to re-enable it 📺 Full breakdown 👉 youtu.be/BDFHZTzk-AQ #FirmwareDevelopment #EmbeddedTips

ISR (Interrupt Service Routine) best practices: ⚠️ Keep it short ✅ Avoid delay(), malloc(), printf() 🧵 Offload heavy tasks to main loop ⛓️ Use volatile variables for shared data One bad ISR = system-wide instability #EmbeddedTips #FirmwareDev

🔧 Smooth Button Presses! Use software debouncing to eliminate false triggers and ensure reliable switch inputs in embedded systems. 🚀 #InnotratLabs # IoT #EmbeddedTips #IoT

#EmbeddedTips "gitk" command can be used to get the visual representation of the history of the repository. #embeddedsystem #linux #github #cpp

#Embeddedtips The number x is power of two ( x == 2^n == 1 << n ), if it has only one bit ( nth bit ) is set to 1 . Way to test it is : " x & ( x-1 ) == 0" #embeddedsystem #linux #cpp #IoT #c

#embeddedtips 1. Use "strace" linux command tool to trace the system calls in your project. 2. Use "lstrace" linux command tool to trace the library calls. #embeddedsystem #linux #c #cpp

#Embeddedtips Structure-based fetching of data offers better performance,reliability and maintainbility compared to string based fetching in context of embedded system where efficiency and resource ultilization is critical. #embeddedsystem #Linux #firmaware #cyancore #visorfolks

#Embeddedtips Use " perf c2c record or perf c2c report " i.e. Linux Perf C2C tool to debug false sharing in multithread applications #cpp #cplusplus #linux #embeddedsystem

#EmbeddedTips You can cleanly quit QEMU by pressing Ctrl + A key and then X without Ctrl key #qemu #embeddedsystem #cpp #firmware

#embeddedtips #wireshark provides complete details of packets flows over the #network . If you just want to see if there are any flows, where they go, and which protocol they use, consider a tool called "ntopng". #embeddedsystem #cpp #linux #networking #networksecurity

#EmbeddedTips Use "valgrind --tool=cachegrind ./yourexeprogram" command which uses cachegrind tool to identify areas of code that might be causing inefficient cache usage, allowing for optimization . #embeddedsystem #linux #cpp #c #firmware #IoT

#embeddedtips 1. Use "ext2ls mmc 0" command which is the equivalent of running "ls" on the SD card’s filesystem. #linux #firmware

#EmbeddedTips 1. Use "ping DNS/IP address" command line utility to troubleshoot networking issues. 2. Use " tracert DNS/IP address" command line utility to ping each router on its way to destination. #networking #networksecurity #embeddedsystem #InternetOfThings

#EmbeddedTips 1. Use "bt" ( backtrace ) command while using #gdb debug tool to backtrack the stack. 2. Use "full" command while using #gdb tool to show the local variables contained in each stack frame. #embeddedsystem #IoT #c #cpp #Debugging

#EmbeddedTips The GNU development tool to examine compiled binaries -> objdump Syntax -> objdump -M intel -D a.out ( your binary file ) #embeddedsystem #Embedded #IoT #firmware
