Questions / Re: Balanduino board dead!!
« on: December 20, 2015, 05:45:56 PM »
Hi Newman,

Sorry to hear that you board stopped working. Have you shorted out the board somehow? As the those two components are the 5V and 3.3V regulators, so either they are blown or something is drawing a lot of current.

Do you have a multimeter? Can you measure if the 3.3V or 5V rail is shorted out to ground?

Yes it just another way of doing the same thing. Please see the following section of the code: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Tools.ino.

As I wrote in my last response, you will have to implement your desired functionality yourself.

No, X and Y simply refers to x-, and y-coordinates, so it in order to make it turn fulll right you could send:
Code: [Select]
CJ,1,0;

If you want to control the wheel velocity you will need to expand the API, as the current API does not support this.

Yes you can properly do this with a PID controller.

Hi,

You can simply send an 'm' via the serial monitor in order to see all the available commands. You can also see the code that is printed here: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Tools.ino#L63-L107.

You properly want to use the following command:
Code: [Select]
CJ,x,y;
Where x and y, are values between [-1:1].

I'm doing fine thanks :)

You should change the following values: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Balanduino.h#L210-L232. You can just adjust them based on the ratio between the new and old wheels.

What kind of wheels are you using? Please also keep me updated if they improve the performance or not.

No not currently. Most my work is currently asking peoples questions and support in general. If you have any specific in mind you are more than welcome to add it yourself and send a pull request :D

@wangxinhao
First of all please remove the -F option from Avrdude, as you risk bricking the chip.

Are you using a 3.3V programmer? Note that the Balanduino operates at 3.3V and using a 5V programmer might destroy the hardware!

Btw why are you burning the re-bootloader? Did you have any problems with the one it came with?

@lebenj

I found a bug in the library used for the USB Host communication, so I had to release a new version again: https://github.com/TKJElectronics/BalanduinoAndroidApp/releases/tag/0.6.3.

It should be on Google Play shortly.

Please report back if you have any issue to get it working.

@lebenj

I just fixed the problem and released a new version of the app: https://github.com/TKJElectronics/BalanduinoAndroidApp/releases/tag/0.6.2. It should be available at the Google Play in a matter of hours, when Google has updated their servers.

Thanks for your feedback!

@Jimmy
This can be done by adjusting the maximum controller angle. It can be done by sending:
Code: [Select]
SA,angle;

Via the serial monitor - see: https://github.com/TKJElectronics/Balanduino/blob/master/Firmware/Balanduino/Tools.ino#L83. You should see the full list of commands when you open it.

It can also be adjusted in the different apps provided, like the Android app etc.

Questions / Re: Specifications DC Motors
« on: February 12, 2015, 02:18:56 PM »
@qte
They are 12V geared DC motors with a gear ratio of 1:30, making 350RPM at full speed with about 400mA freerun and 5A stall.
The built in encoders have a resolution of 64 counts per revolution, with a gear ration of 1:29 will give you 1856 counts per revolution of the wheel.

Looking good! :)

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

Software development / Re: Values of PID and Zones?
« on: December 02, 2014, 04:42:31 AM »
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.
