Make a USBTiny with Arduino?

Projects General Guidance
1

I have to flash a Gen6 Mendel 3d Printer firmware via the 6 pin ISP port. Instead of purchasing a USBTinyISP programmer, I was curious if it would be possible to convert my Arduino board into a USBTinyISP and if possible, what would I need to do it? Thanks and all the help is appreciated. (I have seen that there is an example ISP programmer in the Aurduino, so it's more or less the hardware side that I am curious about.)

Hi WIll,

sure you can, there are a lot of good references to do this and the programmer is listed as "Arduino as ISP" under the "tools-> programmer" in the Arduino IDE.

here is the link http://arduino.cc/en/Tutorial/ArduinoISP

Cheers Pete.

Pete,

Thanks, I did see this and this is where hope was spawned =).

I was hoping there was something that would show me how to connect to the 6 or 10 pin cable instead of directly to the chip. The Gen6 Mendel board chip cannot be removed. Here is a link to what the board looks like. Notice the connector I am trying to tap into is right behind the reset button.

Here is the cable breakout...


I suppose I don't need an ISP cable, I can just use some of the female single jumper cables to connect to it.

I just want to make sure that I don't blast the Gen6 board... I want to get it right the first time. Thanks again, and I really appreciate the help.

OK so that is easy :slight_smile:

tha ISP header you see will be the same as the ones on the Arduino boards. It has become a standard

type "arduino isp header" into Google and look at the images .. lots of wiring examples there for you.

this is what you are looking for

Pete,

Exactly what I'm looking for! Thanks for the help. Just to close the loop, once I do this successfully, I will let you know. Thanks again.
