Firmware won’t upload to a Diecimila ATMega168

[Anonymous]

I am trying to compile and upload the Makelangelo firmware to an Arduino Diecimila ATMega168. Will the firmware fit on a ATMega168 chip? Will swapping in a ATMega328 chip fix this error? I get the following message (error message below).

Sure you have the correct board selected under tools/board

Definitely have the correct board in tools.

The code won’t fit on the chip and even if it did there isn’t enough ram. Like trying to install windows on a pocket calculator.
The 168 chip isn’t big enough.

Oh! I thought that might be the case. Thanks, for getting back to me so quickly.

I’m going to try and swap in a 328 chip ( with a bootloader on it ) and see if I can get it working – why make this project easy right? I’ve already learnt more about gears, timing belts, stepper motors, arduino software veraions and now chip sets than I thought I ever would. ☺

Installing a ATMega328P chip into a Diecimila worked!

Side note: With the upgrade. I had to upload to the board as a UNO.

Thanks again for the help.

Congratulations, Michael! Doubly so, because you’re the first to post to our updated forums.

Nice. Post a pic of your machine, please.

Thanks!

I fear that a working machine is a way off though 🙂

The firmware seems to be the first of many more hurdles. The servo is fine but the java app won’t turn the steppers for some reason – I know they are wired and working as they rotate with the Adafruit Motorshield V2 sketches.

I can’t seem to find much documentation for the java app, so I am wondering if the firmware installed properly.

In the Java app, connect to the robot and the title should change to say “Makelangelo #[number]”.
In the log pane do you see “Hello, World! I am Drawbot #….”?

Do the jog motor buttons do anything?

Yes it does connect (see log below). But the jog motor buttons do nothing… I thought it might be a voltage problem, but thinking back the steppers turn with the Adafruit sketches. I cranked it up to 12v but still nothing.

I did a little research and the Polargraph has problems with lesser boards – perhaps the Diecimila doesn’t have enough grunt in the memory department (just a stab in the dark – I know nothing about these things technically).

thanks for your patience.

After reading up about the differences between Arduino’s, I realised that I shouldn’t have to get a more powerful board – the chip upgrade should be sufficient. So I found another person with a similar problem – motors not jogging – https://www.marginallyclever.com/forums/topic/makelangelo-motors-not-jogging/

I had the I2C-bus address wrong in the Firmware sketch.
It was: #define SHIELD_ADDRESS (0x61)
and should have been 0x60.

I used this sketch to detect the correct address: http://playground.arduino.cc/Main/I2cScanner

With that the jog motor buttons worked and I was able to send a Hilbert curve to the machine…. and the motors moved! What a feeling to see those things move!!! Very excited to see what this thing will do.
