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 […]

Review: STM32 F3-series Discovery Kit

STM’s STM32 F3 series of microcontrollers offer 32-bit performance with DSP functionality. To make the evaluation of this microcontroller easier, STMicroelectronics offers an evaluation board called the STM32F3DISCOVERY. If you have ever wanted to experiment with an RISC microcontroller that comes with special Digital Signal Processing (DSP) capability, the STM32F3DISCOVERY board might just be the […]

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 […]

Microcontroller Controlled Police Strobe Light

Circuits with flashing LEDs and amazing color combinations are pretty popular. This is probably because they are not only simple but one can literally see the results instantly. Let’s have a look at a microcontroller controlled police strobe light using an ATtiny45 from Atmel. LED flashing circuits have been around for ages and probably always […]

Resuscitate Atmel AVR from CKSEL Fuse-Bit Death

The most common way to ‘kill’ a Atmel AVR microcontroller is by programming fuse bits wrong. Sooner or later every Atmel AVR enthusiast will stumble across a fuse-bit related problem. The most common mistake, a wrong clock source selection through the CKSEL fuse-bit, can be fixed easily. The fuse-bits CKSEL0 through CKSEL3 let the microcontroller […]
