Modules Brushless

This modules are intended for driving brushless motors. This is basically done with polling hall sensors, and updating PWM with a predefined sequence. This polling is optimized in order to permit high rotation speeds

forseen are : - 3-phase brushless motor with digital hall sensors - 3-phase brushless motor with analog hall sensors - perhaps other versions one day

you can see an equivalent project here : http://atmel.com/dyn/resources/prod_documents/doc2596.pdf

These modules run completely on own interrupts (no manage function)

interface will be following :

• init of functions :

void brushless_init(void)

• setting a consign. The speed is optionnal

void brushless_set_parameters(brushless_speed speed, brushless_torque torque)

• get current position and speed. The speed is optional

brushless brushless_get_mesures(void)

• set position counter

void brushless_set_position(brushless_position p)

• register a periodical event

void brushless_register_periodic_event(void (*f)(brushless))
