PIC and AVR Projects

PIC and AVR seem to be the most popular in Embedded Systems Design. Many are in this blog, here is a listing of some of the intersting ones.

PIC and AVR Projects


A simple MSF based NTP server for AVR

An implementation on an AVR board of an SNTP server as described in RFC-2030, ... used the EP2S and matching antennae, manufactured by HKW. The mega8535 microcontroller is in a STK200 development board. The board interfaces to the rest of the world with RS232 and SLIP.

4-channel DMX512 PWM LED Driver Board

This project is a 4 channel DMX512 driver board. It features four power MOSFETs that can be configured to operate in PWM mode or as on/off outputs. The driver can be configured to use any four consecutive addresses across the full 512 channel address range. It can drive LED arrays or low voltage lamps with either an 8 bit (256 step) PWM dimming signal or digital on/off mode under DMX control.

Bootloader for 16F87x

A bootloader enables download of hex-files directly into the flash-memory of a PIC or other microcontroller. The bootloader receives the user program via the PIC's UART and writes it directly to the program memory (self programming). This feature greatly speeds up the development process, because the chip remains in the target circuit and need not be moved between the target circuit and the programmer.

Microchip PIC32 Ethernet Starter Kit

The kit contains a development board with a 32-bit MIPS4k PIC32 microcontroller, a 10/100 Ethernet port, an on-board debugger and programmer, and an OTG USB port. You can get the User's Guide and code examples from the Microchip ESK page.

Beaglebone can now be used to build or prototype Android phone or tablet accessories.

arowboat Android - Community Blog for rowboat project.

The Android platform (from 3.1 onwards) has integrated a specific protocol "Android Open Accessory", which allows external embedded hardware (accessory) to interact with an Android-powered device (Android phone or tablet) in a special accessory mode over USB or Bluetooth interface.

Android accessories are specifically designed to attach to Android-powered devices over USB or Bluetooth and adhere to a simple protocol (Android accessory protocol) that allows them to detect Android-powered devices that support accessory mode.

Android Development Kit for Sitara Microprocessors 

The Android Development Kit from TI is a complete software offering to allow developers of Sitara devices the ability to easily and quickly evaluate the Android OS. The kit provides a stable and fully tested software foundation that can be utilized on a wide range of Sitara hardware including Evaluation Modules and Beagleboard

Digital Signal Processing - DSP

When you are trying to arrive at a complex Embedded Systems and Communications solution, You will think of a DSP. Now that computers and embedded devices are used in most electronic devices, DSP is a way you can process, transform, analyze and generate fast analog data, in Real Time.

Real Time ideally is instantaneous or in sync, in tandem. Not an Zepto Second lost. But in the real world many analog inputs or result outputs can be processed a lot slower. So it is more like, How 'real time' you want, how cost-effective a real-time solution can be provided. If the analog input is slow and the system inertia is high and the user response time is limited by his persistence of vision, you need to make a system just a bit faster, even Microseconds delay may be fine. In yet another case it may be pico seconds.

Digital Signal Processing - DSP

A web page in a browser delays a few milliseconds, you will not notice; but when you talk over the phone a small delay, echo or glitch can be unpleasant.

In a weather station the wind speed, atmospheric pressure and relative humidity are measured as analog signals using special sensors. This is then converted to digital data and fed to an embedded system or computer. The computer software analyzes the data and arrives at some predictions based on past patterns. This system in its simplest form, may not be DSP, but it is the beginning of this science, the first step.
