Atmel AVR ISP Microcontroller Programmer Project

One of the frustrating part in learning AVR microcontroller for the beginners is the AVR microcontroller programmer. The question is how to program my AVR mircrocontroller; actually if you googling on the internet and search for AVR ISP Programmer there are plenty information; start from simply using your PC parallel port to the sophisticated Atmel owned AVRISP mkII programmer. This will rise another questi ...

USB AVR programmer

I’ve already had a programmer for Atmel’s AVR microcontrollers, but I couldn’t use it in my lab, because my laptop doesn’t have a LPT port. So I decided to make a new programmer with USB connection. I’ve found an open source programmer AVR doper, and for the basis I took a modified version from the http://www.kreuzholzen.de web page. I designed a new singled sided PCB board, that I was able to make at home. ...

USB AVR in-system Programmer using ATtiny2313

Introduction. Nowadays, USB is the most popular connection between PC and peripherals such as AVR programmers, printers, scanners etc. For that reason I had to modify my old serial AVR In-System-Programmer (ISP) to work with USB connection. You can say, "use a USB to Serial adaptor to connect your AVR ISP with your PC". Yes, that could be a solution but it would cost me more money than a singe FT232BM chip  ...

AvrUsb500 — an open source Atmel AVR Programmer using ATmega8

Why Stk500 and USB? Until the beginning of this year a simple parallel port programmer was the only good programmer as it could be used for any device. All device dependent information is stored in the programmer software on your computer. The problem is however that the parallel port is slowly disappearing. Apple does not have it at all and the smaller laptops don't have it either anymore. It's time to loo ...

Build your own PICkit 2 programmer

There are many PIC programmer available, commercial and DIY devices. As Microchip introduces the new microprocessors the programming software got to be updated accordingly playing catch-up with the PIC manufacturer. That is the root of the problem with third-party PIC programmers. Microchip's PICkit 2 is the low cost ICSP programmer for Flash PICs with USB interface introduced by Microchip. Only subset of P ...

FabISP, a fab-able in-system programmer using ATtiny44

The FabISP is an in-system programmer for AVR microcontrollers, designed for production within a FabLab. That is, it allows you to program the microcontrollers on other boards you make, using nothing but a USB cable and 6-pin IDC to 6-pin IDC cable. It's based on the USBtiny and V-USB firmwares, which allow the ATtiny44 to perform USB communication in software. Programming can be done through avrdude. The s ...

AT89LP2052 / AT89LP4052 Parallel Port Programmer

Programming the AT89 LP2052/LP4052 Flash Memory, Lock Bits and User Fuses The AT 89LP2052 / 89LP4052  microcontroller provide two interfaces with same command format for device programming. The serial ISP Programming interface of the new 2052/4052 microcontroller needs one additional SS Signal for device programming. This SPI signal will be added in the near future to the existing AT89ISP cable and Software ...
