simple atmega8 programmer

Hi Every Body

Do you know how to build simple ATMEGA 128 Programmer.
I Have tried STK200/300 Schematic (Interfaced with LPT ) But I had Used 74LS244
instead of 74HC244 .But It Doesn't work.

Can STK200/300 Support ATMEGA?
Which Voltage is used for Programming FLASH MEM And EEPROM (5 Or 12)?

What is the Latest AVR Studio Version which Can Support STK200/300?
Regards

avrprog max232 isp programmer

I have a circuit about AVR Programmer. But use the 74HCT541 . I use it download code to AT90S8515 well. It maybe can useful in ATmega series. If you need it . Please give me your e-mail. I will mail to you recently.
My E-mail: bear@zytc.com.tw

Best Regards

avr lpt 74ls244 programmer

A quite easy programmer is the ponyprog interface:

The software is among the most complete for one that doesn't use AVR Studio.

Another even simpler one I've used before is:
https://www.speedy-bl.com/avr-prog-e.htm
https://www.speedy-bl.com/adapter-e.htm
Either use a parallel port adaptor on first link or Sercon2 on the second.
This programmer software has size limitation unless you register it though.

if you're willing to try something not quite simple, give this a go:
https://avr.openchip.org/bootice/
These are working plans to build a completely atmel compatable JTAG adaptor. The catch is the adaptor itself requires and ATmega16 so you'll have to build a simple serial programmer or something anyway for a start. Unfortunately the second programmer I suggested above wont program this micro unless it's registered, as it has a size limitation.
If you don't know what the Jtag adaptor is, well it allows you to program and debug a micro in-circuit using AVR Studio, you can step through the code, set breakpoints, watch registers/variables, the works, all as it's running on the chip itself so you can see it affecting the hardware as you're stepping. I'd had a lend of an official atmel jtag before I made my own from these plans, and the home made one actually works more smoothly than the official one. Once you've experienced in circuit debugging you'll wonder how you ever developed without it ;)

speedy bl schematic

There is difference between 74HC and 74LS
74LS takes high impedance as high state
74HC takes high impedance as low state

IN parallel port there is open collector outputs for control port

so use only 74LS244. The same pbm occured to me when i made IC tester using parallel port

for my e-books on parallel port see this link

atmega8 programmer 74

Sorry Sunsina,

This one (post) is not about your programmer...
It is just to tell Njbibin that LS stand for Low Power Schottky and HC stands for High Speed CMOS and it has nothing to do with impedancies or low or high states...

avr programmer lpt 74hc

Hi,

I have built ATMEGA 128 programmer using max232 and AT90s2313 with AVRPROG.exe, you can easily built these programmer, no need of 74 series IC.

regards
