Programmers

These are simple AVR programmers. I designed and built four different programmers for various envilonments: LPT controlled parallel programmer, LPT controlled ISP adapter, COM controlled ISP adapter and COM controlled generic SPI bridge. Additionaly, COM controlled adapters can be used as a communication cable between host PC and target board, it is useful for debugging.

Anyway, Fluffy is a SX programmer for people who have already experimented with PIC chips, and want to try out the Scenix SX family. I built Fluffy because I wanted to experiment with the SX's, but didn't want to spend $300 or so bucks on the official development system. To build it, you will need a PIC16F84 (a 16C84 will probably also work, but I don't have any to test!). Note that this implies you should already have a working PIC programmer. If you don't, you might want to check out COM84, or any of the multitude of free, cheap PIC programmers available on the web.

This circuit is a combination of a ludipipo programmer (for pic) + phoenix programmer (for the eeprom 24LC16). You can't program pic and eeprom with ludipipo programmer. The big advantage of this circuit is that use just one port from your computer (RS232) in reverse with other programmers that use both RS232 and parallel. The disadvantage is that you must select the component to be programmed with a switch and not electrically and that you can only program 16F84 and 24LC16 (gold wafer cards). Nothing else :-(

It's very easy! This is a simple GAL programmer that hobbyists will able to use the GAL very easy. Building costs are less than 1/10 of cheaper GAL programmers. This is good for parsonal use. And added an optional function to program to the Microchip's PIC with using a socket converter.

The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy and fast. If you need more code space for your application, particularly for developing 89Cxx projects with C language. Atmel offers a broad range of microcontrollers based on the 8051 architecture, with on-chip Flash program memory.

This is a JENS MADSEN 'S project I've built to program my pic and EEPROM (16xXXX AND 12CXXX AND 24CXX) I use it with ic-prog , it is little ,simply to build ,cheap and give few bugs.

This programmer has been designed for use with a domestic heating boiler. It provides outputs via two relays to control the supply of Hot Water and Heating. There are 10 program entries available and each one can control the heating and water independently. The programmer allows manual advance of the heating and water and disabling of program control, useful if you're going away for a few days and want to leave the heating and water off. As well as providing normal front panel switch control of the heating and water, the programmer also features a serial terminal interface that allows it to be operated remotely from a PC running a Terminal Emulator.

This programmer is designed to program Atmel AVR microcontrollers in either parallel or serial mode, while connected to a host machine using RS232. It's controlled by an 8051 (actually developed using a Dallas DS5000) and should work with most variants, since it doesn't use any special features. I hope it won't be too difficult to modify for use with an 8031 (external ROM) or one of Don's DT103 Simmsticks.
