//电动车双闭环程序，采用双闭环方式控制电机，以得到最好的zh转速性能，并且可以

//限制电机的最大电流。本应用程序用到两个CCP部件，其中CCP1用于PWM输出，以控

//制电机电压；CCP2用于触发AD，定时器TMR2、TMR1，INT中断，RB口电平变化中断，

//看门狗以及6个通用I/O口

-//Double loop electric vehicle program, using double-loop control the motor speed zh to get the best performance, and can// limit the maximum motor current. This application uses two CCP components, which CCP1 PWM output is used to control// system of the motor voltage　CCP2 used to trigger AD, the timer TMR2, TMR1, INT interrupt, RB port change interrupt// to see watchdog and the six general purpose I/O port
