Topic: Arduino Mega ADK Demokit problem (Read 2491 times) previous topic - next topic

Hi all,

I just received a arduino Mega ADk board for one of my project but when i tried to upload the demokit code from the google ADK to the board, i get the error below.

I already have capsense library, USB host shield library and android accessory library installed.

Code: [Select]
demokit:52: error: 'CapSense' does not name a type
demokit.pde: In function 'void setup()':
demokit:120: error: 'touch_robot' was not declared in this scope
demokit.pde: In function 'void loop()':
demokit:250: error: 'touch_robot' was not declared in this scope


Thanks in advance.


AWOL

I think you need to check you've got the CapacitiveSensor library installed, and that the variables and classes are correctly named.
For some reason, they appear to have different names in the most recent releases.

I have the same problem
I have installed (arduino 1.0.3) in opt /

in opt/arduino-1.0.3/libraries I copied the folders (AndroidAccessory, CapSense and USB_Host_Shield)

i got the CapSense's  folder by changing the name of the extracted folder (arduino-libraries-CapacitiveSensor-b297f3f.zip) taken from  related link (CapacitiveSensor04.zip).

I have tried to upload as root in Ubuntu 12.04 64 bit

in file / examples / CapSense / CapitiveSensorSketch I did not find problems  uploading to the board


So, I've changed in the lines with errors (CapSense) by (CapacitiveSensor).
considering that the class  is now  named  (CapacitiveSensor) at CapSense library v.04
and the library is now called  CapacitiveSensor as well

now i can upload, sorry for my English

I also have the same problem

i have used the code of Jhojan 

but i stil get a error

in this line:
int len = acc.read(msg, sizeof(msg), 1);

the error:
C:\Program Files\arduino-1.0.3\libraries\AndroidAccessory/AndroidAccessory.h: In function 'void loop()':
C:\Program Files\arduino-1.0.3\libraries\AndroidAccessory/AndroidAccessory.h:65: error: 'int AndroidAccessory::read(void*, int, unsigned int)' is private
