MultiWii

thanks Pyrofer, sorry for the late reply Its a good idea to accomadate a power distribution, but then. On the same board, then it will ghave to be 4 layers, with 35mm copper for the power lines. Then it will be expensive. Another possibility is to have a Power distribution board separate, with even ...

Thanks Pyrofer. Are there all in one boards with Atmel 2560?
With Atmel 2560, Hope that it can take future upgradations like GPS etc. I thoughty of putting some efforts just for knowledge and fun.

I made 15 boards and sold all ofthem at cost price to fellow modellers. Now i want to revice this board with a new atmel processor. I request ...

Thanks PartrikE. I treid thsi as you suggested. Same IC config has different values declared. However, with lot of trial and error, i fixd the following values and it seems to work. #define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = Y; accADC[PITCH] = -X; accADC[YAW] = Z;}// This combination works for...

i designed my own board with these sensors. I made 15 such boards and gave it to my friends in banagalore at cost price. Up to 1.9 Vesrsion the baord worked with the standard setiings. With 2.0 it dosn'nt. Waht is the standard way of doing this.

hello, Kidly help me I successfully down loaded Ver 2.0 and the sketch was down loaded to my board.

With these changes all vesrsions up to 1.9 ...

thanks Allex. i will try some PID tuning and will report

yes. but pl give me some tips to make it work!
it was kind of working with the dev version dev20110725
and why is
" with dev20110725 the ALT value displayed is 207.88

thanks mr.rc-cam for such clear and crisp reply.

hello all, wanted a clarification. Will the latest code 1.9 support the I2C R/W test and show in debug2 window of the GUI? Or do i have to write the patch as discribed in the begining of this thread? Some where i read that the debug2 value should be -1 and not zero if it is working. kindly clarify b...
