Error uploading software

[johanb]

Hi!
I recently bought the Atmegatron but haven't been able to upload any new software. I checked the other posts about it, but still couldn't figure out what's wrong (ie I checked that the cable is correctly inserted, I've flipped the programmer/midi switch to the left etc..). So far I've tried the Delayertron, the Odytron and the Atmegadrum software but no luck.

This is the cable I am using:
https://www.elfa.se/en/usb-cable-assembly-usb-ttl-cmos-ftdi-ttl-232r-5v/p/17320673?queryFromSuggest=true

With the VCP drivers from here:
http://www.ftdichip.com/Drivers/VCP.htm



This is the error messages I keep getting:
Arduino: 1.6.5 (Windows 7), Board: "Arduino/Genuino Uno"

Sketch uses 25,400 bytes (78%) of program storage space. Maximum is 32,256 bytes.

Global variables use 1,943 bytes (94%) of dynamic memory, leaving 105 bytes for local variables. Maximum is 2,048 bytes.

Low memory available, stability problems may occur.

Any ideas?

Hi,
This means that the Arduino software can't connect with the Atmegatron.  I have recently discovered that there is an FTDI cable that doesn't have the standard wiring.  Can I check the following:
With the cable plugged in and viewed from above, the order of wires should be (from the left):
Black
Brown
Red
Orange
Yellow
Green

If this is correct, give the switch a couple of flicks back and forth (and ending with it on the left when viewed from above).  Sometimes the connections aren't fully switched across.

Finally, check that you have the FTDI cable selected in the Arduino software in Tools->Port.  It is usally the bottom option if you don't have any other serial connections.

Let me know how you get on!

So I managed to get it working properly!

I was using the ftdi driver recomended by the manufacturer of the cable (the one I linked to above), but when I uninstalled that one and had Windows go look for the driver on Windows Update suddenly everything started to work.

So a suggestion to other new users is to start by installing the Arduino IDE, then plug in the FTDI cable and let Windows get the driver for you.

Now off to some composing....
