Arduino as AVR Programmer

For my project I need two Arduino boards, but I have only one Arduino Mega 2560 board (refer Fig. 1). I can either buy an Arduino Uno board (that costs approx. Rs. 1400 in India) or I can make an Arduino board using a fresh ATmega328/ATmega328P chip. Suppose you have an Arduino board that is built on ATmega328P or ATMega8A-PU chip and, due to some reasons, the chip has gone bad (like in my case). You can bu ...

Do you know, what´s a top-class programmable power supply capable of?

Imagine a laboratory (testing) power supply able to provide a virtually any function. Switching on, drop-out, repeated switch-on and many other functions, by which we can test our product in a „single shot“ - those are programmable laboratory power supplies from company TDK Lambda. Perhaps the biggest advantage of programmable power supply is the fact, that there´s no need to adjust, watch, set at testing i ...

USB PIC Programmer

DSCF2015 This page is dedicated to everybody needs to program a PIC (Microchip) device via USB port. Looking on the web for ready-to-use projects, I found a good one called Open Programmer, coming with several schematics, PCBs and Open Source code. The original link is http://openprog.altervista.org/OP_ita.html What concerned me was the need to mount, on the mainboard, a specific socket board depending on t ...

Easy Auto Programmer

From project to project the number of hex files on our PC was increasing. Many people send us their virgin ATMegas to get them flashed. And last not least distributing PCB's and pre-flahed chips via agile-hardware forced us to burn many, many AVRs. In principle this is a work an ape should do but reality was different. So we spend munch time in this boring job. To much time ... Thus it was just consequent t ...

ORIGINAL PICKIT-2 MICROCONTROLLER PROGRAMMER

These days I was thinking about a better PIC programmer that can work with Microchip MPLAB IDE software so that I can write my own programs or edit someone else’s programs. I found that there are numerous versions of the famous Microchip PICkit 2 on the web. Some of them are using the original schematic published by Microchip and some are lite versions – with different parts or simplified schematics. None o ...

Introducing the TinyLoadr AVR Programmer

I finally finished the next version of my TinyLoadr AVR programming Shield – and it’s not a shield. It’s a standalone USB programmer, so you no longer have to have an extra Arduino laying around. The best part? It’s the same price as the shield was! Read more to find out more about it, or visit my Tindie store to grab one for yourself! Features at a glance Open source. Supports a wide range of AVRs (see lis ...

How to Convert an Arduino into an AVR Flash Programmer

In case you don't have an AVR programmer but you do have an arduino, the arduino can be converted into an AVR flash programmer, meaning it can program bare AVR microcontroller chips. Say if you have an AVR chip and you want to program the chip, so that the program that you've written and compiled gets stored into the flash memory of the chip to be executed. The arduino, with some specific wiring, can act as ...

ATtiny programmer using Arduino ISP

Thanks to: http://jeonlab.wordpress.com/ For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC)  and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude). I'd like to share how I program ATtin ...

My Arduino In Circuit Programmer

This Lazy Old Geek is also an Arduino Geek. If you are an Arduino Geek, one of the common microcontrollers used by Arduinos is the Atmega328 chip. In order to use Arduino software, the Atmega must have bootloader software on it. Okay, so I bought some blank Atmega328-PU chips from Mouser.com. TIP: If you want to make your life simpler, order the Atmega328P-PU chips instead of the Atmega328-PU chips. I didn’ ...
