i think two pin mappings need to change like this.

MultiWii Board                     Peripheral Connection
-------------------------------------------------------------------------
#define DIR_L2 12                           L293-Pin7
#define DIR_R1 8                            L293-Pin15

The sensors (gyro / acc) are interfaced through I2C, so you don't need to do any thing there Smiley
Just do the modifications in code as suggested by akhilzid, and you are ready to go !

You will not be able drive a l293 just by reassigning the pins in
the multiwii code .

the output  for multiwii is ppm - used for driving servos and esc's (using write() and
writeMicroseconds() ) this will not work with l293 which requires PWM.(using digital write() )

You need to change some other parts of the code also - and
please let me know once you have found out.

Hey, dude, you should read the previous posts, we are not speaking about multiwii code, I have given link to a instructible , the code in it can be easily run in multiwii board.

I tried uploading the code & rigged up the bot, but did not see any movement in bot. (Multiwii+L298+Motors+Battery)

Later I tried uploading the multiwii firmware with airplane configuration, This too did not make any difference. I dont see bot moving or cant even stand. (Multiwii+Single brushed ESC+2 DC Motors+Battery)

But my multiwii board seems to be working fine. I can see that on the multiwii tool.

Not sure what is the issue, will have to check it tonight..

Hi Saikat,
Any luck with your bot?
Mine still having issues using L298.
BTW how did you wire your bot with servos? On multiwii board, which pins did you connect the servos to? Can you please share the schematic of your bot with servos?

!!Wish You All Very Happy New Year!!
Did you all have any progress on this? Please post your update.
My progress is, wheels rotates to the direction either forward or backward the way multiwii board tilts to. But balancing doesn't happen. Looking into this issue.

Thanks
