Standard Peripherals Library vs CMSIS vs HAL vs Low Level Library

Tags: ARM, C, Electronics, Embedded, Programming

The STM32 line of microcontrollers offer a bunch of features in a nice package at reasonable cost, something I like. What I don't like as much are the development libraries around it provided by ST. For this reason, most of the time I stick to writing code using the 'Cortex Microcontroller Software Interface Standard' (CMSIS) and the datasheet, and this works nicely but can be slow to develop. While it's still my personal favorite, I recently checked out the other options to see where things are going to do the prep work for some ports of older projects built using the 'Standard Peripherals Library' to newer processors such as the STM32L4.

Transparent Caching Proxy with Squid and Just One Ethernet Port

Tags: ARM, Efika, Linux, Network, Squid

Some time ago we had a project which needed a simple transparent caching proxy for use in classrooms in Latin America. The classroom desktops consisted of ten of our Efika's, and we thought why not use an extra one of those to act as the proxy. This is not the kind of high bandwidth environment of a typical installation, so the performance limitations were not really an obstacle. The goal was rather to use the limited internet connection available as efficiently as possible. The configuration of the system using Squid is detailed below.

The Freescale Technology Forum is well underway here in San Antonio. We have a booth where Genesi are showing our latest developments and systems. I'll post some pictures later, but for now here is an interview with Konstantinos explaining some of the work we're doing on ArmHF.
