Getting Started / Re: Latest version of PCB

Hi Ryan.

The changes that has been done on the schematic is some pin-allocation changes, where some of the periphiral pins has been reassigned. Notice the "Microcontroller" section.
More specific we moved around with the encoder pins to optimize the interrupt routine for easier and faster reading. By doing this we also freed up the extra available Hardware UART found in the ATMEGA1284 chip which has been exposed at the external female header, SV2.

To use CPROXY under Windows 7, please try to install CPROXY to different drive, for example to D:CPROXY folder.

I haven't checked it yet. But of course I'll do it soon. I haven't posted my code because I writed it from a scratch today and I would like to update it so there wasn't such mess in it. I will do it in next few days and when I finish I will let you know :)

Looking good! :)

Can it handle slopes as well? And is your code available somewhere, so I can take a look?

I finally did it! I've got my new PCB and now I'm able to tune PID and control robot from my PC's keyboard. After hours of  tuning I achieved following result:

It is on my code with two PID loops in cascade setup. I think it works quite well. Thank you very much for all your help. I woldn't do it withoult you Lauszus :)

Hi Zara,

Sorry for not getting back to you!

I started by finding the value for positionScaleD and then just moved by way outward until it came back smoothly once you pushed it.

I believe I added velocityScaleStop afterwards to smooth it out a little bit more afterwards.

Hi Reinier,

You will have to include the following file from the USB Host library: https://github.com/felis/USB_Host_Shield_2.0/blob/master/avrpins.h.

You can read more about why here: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Balanduino.h#L53-L56.

Lauszus
