Arduino |Automatically Save Variables to EEPROM on Power-Down

A recurring challenge for Arduino projects is that variables are volatile and will be lost completely unless previously stored to some sort of non-volatile storage such as de inbuilt EEPROM. This article shows a minimalistic approach to detect sudden loss of power and automatically store a variable to an EEPROM adress. First I should mention […]

Diamex Prog-S2 | Arduino IDE

The Diamex Prog-S2 is an universal USB ISP programmer vor various microcontrollers including Atmel AVRs. This article shows how to integrate the programmer into the Arduino IDE There are a few articles on the web that talk about the Diamex Prog-S2 and Arduino. But it seemed to me like they were either outdated or faulty. […]

Realtime GPS Tracker w. SD Card Logger Part 2 | Google Maps Link

This article shows how to build a realtime text message GPS tracker with integrated SD card logger. It allows coarse realtime tracking and more precise post analysis through the logged data. Not too long ago I wrote an article featuring a Realtime GPS Tracker w. SD Card Logger. That project sends raw NMEA [1] sentences […]

Review: ADSP-BF592 EZ Lite Kit

Blackfin processors from Analog Devices (ADI) precede their reputation. Anyone who has even remotely thought about Digital Signal Processors (DSPs) has come across ADI’s Blackfin processor series. ADI considers the BF592 as the low-cost entry point into the Blackfin portfolio of processors. To make evaluation a piece of cake, ADI offers the BF592 EZ-KIT Lite […]

Freescale’s Kinetis L-Series ARM® Cortex™-M0+ based MCUs

Freescale announced a new line of ARM® Cortex™-M0+ based microcontrollers, the Kinetis L Series. The MCUs are supposed to offer the performance of a real 32-bit MCU at the price and energy rating of an 8-bit microcontroller. A tight budget and low power requirements used to limit design engineers to 8-bit and 16-bit MCUs. Freescale’s […]
