So how does it work when the ATmega expects 5V? For serial TTL communication you really only need pins 6, 7 and 8. Please read the entire article before you begin to modify the cable. Posted on Sep 23, I did not unsolder them for fear of breaking some unknown connection, rather I simply clipped them at their pads.

Your answer needs to include more details to help people. What jsb heart breaker! However, mine only has 4 wires, and they connect to instead of 4 Precautions Never work on a live circuit! Currently the problem is i am getting garbage values in the serial communication as described above… sending 10xM to arduino, the result is few M display on LCD and other become garbage characters… why?

I can easily find out which of the 3 wires went uusb where, but how should I find the pinouts of the other pins? Wear an anti-static wrist strap. If you try to exceed mA, bad things can happen.
Want Answer 0 Clicking this will make more experts see the question and we will remind you when it gets answered. Make sure the power is off and the cable is not plugged into the USB port.
When attempting to program, the DTR pin does go low, but it stays low, keeping the Arduino in reset instead of actually resetting the Arduino. For my cable pin 6 was white, pin 7 sku-5 blue, and pin 8 was black. But if I want a 9-pin RS serial port, I may need more pins.
Mar 21, Nokia i Cellular Phone. The methods described here should work in general for cables using different chips.
I also had two additional wires, one green pin 3one red pin 4. Recent versions diu-5 Linux have the driver pre-installed. Can you do me and all the future readers a favor and measure the maximum current you can draw?

Check out his blog too, he posts some cool […]. RS uses a negative voltage for a logical 1 and a positive voltage for a logical 0. The picture is deceptive; things are much smaller than they appear! I do not know how this aurt values comes.
