Hey Everybody,
My final year project is of TRAPEZOIDAL CONTROL OF SENSORLESS BLDC MOTOR using BEMF method.
But now i m facing problems in the design of the electronic circuit, the circuit includes microcontroller, 6 pulse inverter circuit giving supply to sensorless bldc motor and a zero crossing circuit for BEMF detection and feedback. Can any body help with the idea of trapezoidal control.
please do reply.

Missed this the first time, but Picmicro have many app notes on BLDC and motor control in general, including code.
Also the development board PICDEM MC LV has schematics and code,
