i have made the quadrotor project done by columbia university as my reference.
and we tryed testing  the motor based on the circuit provided by them and the result was that i blowed up the signal generator of my college.
and then carried out the mini-lift by directly connecting the ESCs to the receiver end and the test was successful.
am having two dual axis accelerometer-ADXL213
and one gyro-ADXRS613 and also PIC18F4431....now how should i alter the circuit,since the columbia guys used brushed dc motors.
how should i connect the ESC outputs to the microcontroller .

If you read quad related threads on this forum, the first question is how much you want to build yourself using PICs etc (soldering your own microcontrollers and sensors) and how much you want ready-made (just adjust some software, put things together and do flight tests).

Welcome to RC India Smiley

Looks like you also joined and posted a quad related question in 10 minutes Wink There is much discussion about quads here, including offers from people who professionally guide people building quads.  Please "search" the forum, that should give you a good head start.

I am merging this question into one of the quad related threads.

No, it cannot be built using that series of micro controller as it doesn't have 16bit timer nor buit in adc port and Low MIPS all of which are crucial in controlling of quadcopter. Would suggest Atmega architecture with atleast a 32k memory ideal.

....And if you're familiar/experienced with u-controller programming, you can go for STM32 processor. It outperforms all these 8-bit processors and gives you excellent results. Debug and flash tools are readily available too.
