برد لیچی پای زیرو یکی از ارزان ترین کامپیوترهای تک برده مبتنی بر سیستم عامل لینوکس است که متشکل از برد زیرو و ماژول وایفای است. برد که در ابعاد کوچکی کمی بیشتر از اندازه یک کارت SD طراحی و عرضه شده است. برد اصلی از پردازنده آلوینر V3s با معماری کرتکس A7 با رم داخلی 64 مگابایتی بهره می برد. این برد از یک السیدی 5 اینچی پشتیبانی می کند که مستقیما از طریق کانکت...

The lwIP provides two APIs for use by applications: RAW API: The raw API is customized for high performance and lower memory overhead. The limitation of raw API is that it is callback-based, and consequently does not provide portability to other TCP stacks. Best Performance & Code Size Complex For Application Development Socket API: The socket API provides a BSD socket-style interface and is very portable; however, this mode is not as efficient as raw API mode in performance and memory requirements. BSD Socket-style API → (Open-Read-Write-Close) Very Portable...

$ gcc -Wall calc.c /usr/lib/libm.a -o calc Correct Order $ gcc -Wall calc.c -lm -o calc Error! Incorrect Order $ gcc -Wall -lm calc.c -o calc In general, the compiler option ‘-lNAME’ will attempt to link object files with a library file ‘libNAME.a’ in the standard library directories. On systems supporting both 64 and 32-bit executables, the 64-bit versions of the libraries will often be stored in ‘/usr/lib64’ and ‘/lib64’, with the 32-bit versions in ‘/usr/lib’ and ‘/lib’....

پروژه Yocto : مجموعه ابزارهای منبع آزاد برای ساختن سیستمهای سفارشی توکار YOCTO is just another way to build uBoot, Linux Keel & Filesystem. Difference from the standard direct compilation is, that Freescale now officially adds all their support through YOCTO. The Yocto project provides a reference build system for embedded Linux, called Poky, which has the BitBake and OpenEmbedded-Core (OE-Core) projects at its base. The purpose of Poky is to build the components needed for an embedded Linux product, namely: - A bootloader image - A Linux keel image - A root filesystem image - Toolchains and software development kits (SDKs) for application development ادامه مطلب...
