MultiWii

Today i tried to use multiwii 2.0 version BUT....
in taking this error .....gui vs arduino version or buffer size mismatch..
when i'm opening the GUI...working for some second..and then....




Any help ??

Working fine in my Laptop......

sounds like a RXTX jni / windows specific issue to me :

With your workstation , please do some testing with :
- http://code.google.com/p/mwi-gc/downloads/list - C code , it will tell if this is only related to the serial reading
- https://github.com/treymarc/mwi-swing - Java code , it will tell if this in a threading awt issue

the issue is : rxts is not preventing non java code to acces and read the serial port , if other read/pooling are performed during the gui execution : the gui will not receive all the sended serial data -> buffer mismatch

Are you using V1.0 of arduino ide? Checked your board and comm port settings and reflash.

you may want to try at a lower refreh rate

try with

https://github.com/treymarc/mwi-swing/tree/master/build

install those files in the same folder than you multiwiconf and multiwiconf/lib


ps : you may have some others tools monitoring or accessing the serial port , turn off any bluetoths and serial manager.
