Required only a standard PC serial port to program any AVR device supporting. Atmel's in-circuit programming algo- rithm. I wanted it to fit in the serial port's DE9 hood, and I wanted to be able to power it from the serial port. (i.e., no external power supply required). Unlike other low-cost AVR serial port programmers, I wanted. If you don't mind can u send me pdf file of your drawing and part list so i try to make again and see if i am able to program attiny2313 by using pony program.

1. Attiny Serial Port Programmer

I have sucesfully assembled a circuit to use Arduino UNO as a programmer for ATtiny13. Download nfs underground 2 pc iso torrent. However, my plan was to only burn bootloaders to my ATtinys, so that I can program them the very same way I program an Arduino.
Now, I have these parts you can see on the image:And now, there are two questions that are bothering me:

Attiny Serial Port Programmer

1. Is this enough to make a docking station for ATtiny?
2. Which wires from the serial port should I use?

If you manage to burn the Arduino bootloader, than you should be able to upload sketches from the IDE similarly to the technique used for the Single Sided Arduino (through the serial interface).

This circuit reference could be useful:

Concretely the lower-left part of it, which shows the pinouts of the RS232 connector used along with some transistors to lower the potencial 12V to TTL logic. But if the RS232 to USB convertor shown in your photo is the 'PremiumCord ku2-232a',

or a similar one based on the 'FT232RL' chip, than it should output a maximum of 4.9V as HIGH on the RS232 side, according to it's datasheet. Therefore you should be able to safely use it without the transistors.

To the construction of the device: I would just tie the according pins on the ATtiny13 (datasheet): PIN5 on ATtiny13 - MOSI (Master Out Slave In) to PIN3 on the RS232, PIN6 - MISO to PIN2 and the PIN1 - RESET to PIN4. Than PIN4 on ATtiny (GND) to PIN5 on RS232.

But you still need to get 5V from somewhere and it needs to share the same ground with the RS232 connector (preferably from an USB of the same PC).

Hi, I am a newbie in AVR world but have practical experience in electronics. I want to make a simple AVR programmer. I got a hold of serial port programmer which is really simple here:

It should work I guess (Please have a look and tell me if it doesn't). I know that the zeners and resistances are required to step down the voltages. Now I was wondering that if the same can be done with max232 chip? I tried searching the internet but couldn't find anything. All I could find is that max232 can be used for communication between atmega and rs232 port.

Please help
