Microcontroller In Circuit Serial Programming (ICSP) with Microchip PIC and Atmel AVR

Published on February 3, 2012 By codex

In Circuit Serial Programming is a method of directly programming a Microchip PIC or Atmel AVR while in they are connected to a circuit, as opposed to programming the chip ahead, and only then soldering it to a circuit. There are many benefits to ICSP, but also some important design considerations which I will try […]

Published on May 12, 2008 By codex

Design, development and construction of an electronic controller for a CNC machine. The controller controls up to 3 stepper motors (up to 3 axes), has home and limit switches, and is optically isolated from the computer.

Microchip PIC Programmer

Published on March 27, 2008 By codex

This circuit can program any MicroChip processor – from 6 pins to 40 pins processors.The programmer supports: PIC12,PIC16,PIC18,dsPIC24 ,dsPIC30 families, and uses an ICSP header thus not requireing to remove the PIC from the circuit each time it needs to be programmed.

Baby Cry Detector (Cry Recognition)

Published on March 27, 2008 By codex

In this project we created a baby cry detection (recogniton) device. The device can recognize baby-cry while ignoring other sounds like human speech, music, and so on. The project consists of several phases, among them are research, a development of a unique digital signal processing algorithm, software development, physical creation of the circuits, physical creation […]
