The PIC32 micro development boards are designed for learning how to program PIC32 micro applications and for developing PIC32 micro-based projects. The ready-to-use development kits, with fully integrated debugger, are great for everyone just getting started with dsPIC C-programming (like me!).

Linux is becoming a very popular operating system, especially for embedded domain. From 1991 it was continuously developed and now it is one of the most popular operating system. A lot of hardware platforms (microcontrollers) are using embedded Linux, some of them being ARM, PowerPC, Intel.

The RENESAS M16C LCD Display allows both to visualize on a display the data received from an other device and to send a sequence of data string, as a response to a specific request.

ZigBee module with 32-Bit ARM Processor is ideal for remote sensing. California Eastern Laboratories is the only company that offers an IEEE 802.15.4 wireless module with an internal 32-Bit ARM processor. The module named FreeStar Pro is based on Freescale Semiconductor’s MC13224V radio/processor Platform in Package (PiP) chip. It offers lots of memory and I/O ports making it simple to design complex wireless nodes.

This article shows how you may play WAV file created on your PC on an audio embedded system (comprising of a microcontroller, a DAC and a D class amplifier); it will detail the format of WAV files, show how you may extract raw data from them, how you translate it and how you should play it on. PC motherboards have both negative and positive supply voltage, therefore it is relatively easy for them to generate the dual polarity signal required to play a sound in a speaker. But how about audio embedded systems? Their overwhelming majorities (think about the number of mp3 players on the market!) have only positive power supply, so audio data has to be somehow translated to a positive interval.

This article offers open source software (oss) for FAT over MMC SDC. We have many options of open source TCP/IP stack implementations. However we don’t have enough choices for open source FAT file system over popular MMC/SDC, because of commercial reasons. Most of the popular flash cards are covered and protected by patents and copy rights. For an experienced engineer it is easy to hack the protocol, but this will bring legal problems if he releases what he found during the reverse engineering.

The purpose of this article is how to generate analog voltage with digital circuit.
Many times, designers are faced with the need of generating analogue voltage levels in purely digital circuits. Although the market provides today a very broad range of dedicated digital-to-analogue converters, putting such a device in the schematic has a negative impact on the overall cost of the system. There are however, cheap methods of creating the required voltage levels, and even of generating pseudo-analogue signals, using purely digital means.

Stopped by a Datasheet (a Freescale microcontroller)! I just can't believe that M68HC08 family of 8-bit microcontroller did this to me!
A few weeks ago, I was asked to modify a project developed previously by another designer.
This device, among other things was battery operated, had a matrix keyboard, and was managed by a Freescale (read and download the Datasheet).

The UNI/O microcontroller technology has been recently released by Microchip. It consists of a proprietary single I/O bus protocol, where the bus combines the clock and data lines into a single bit stream using the Manchester Encoding technique. Since Microchip already is one of the leading microcontroller and memory devices it is likely that the near future will see an increased use of this pin saving technology.

Usb i/o board (based on a Microchip microcontroller featuring a usb port) allows you to drive relays and read input status, easily and at a low cost (starting from 39 euro).This board is similar to a PLC (Programmable Logic Control) yet, it receives commands from a Personal Computer using USB bus. It is easy to connect using USB because when you plug the USB to the PC, a virtual RS232 port is created so you can easily develop the application software. You can use this board for domotic application, industrial automation, etc...
