          Motor Development Board

          The motor development board is composed of two boards, MCU control board and power driven board. The two boards are connected by a 34-PIN IDC cable.

          Keil Installation
          Follow these steps in ATC_AC781x_DevelopBoard_RM_CH.pdf》, section: Development Environment Preparation to download and install Keil environment.
          Software Packs Path

          TC FOC motor control algorithm software, named ATC_FOC.rar. Unzip the RAR file , the software structure of FOC algorithm can be listed, mainly including the following parts: 

          (1) FOC_App:

          a. Moduleinitialization

          b. Get Hall state,calculate motor speed

          c.PID initialization and  PID controller

          d. Phase currentsampling

          e. ADC interrupt,execute FOC algorithm during ADC interrupt

          (2) foc_control.lib

          a. SVPWMimplementation

          b. Clark/Parktransform implementation

          c. Hall angleself-learning function

          Module Initialization

          The following modules, PWM/PWDT/ADC/GPIO, are ulitilized in the motor control algorithm.  Initialization settings should be done to the above mentioned modules respectively.

          Follow the detailed introduction in 《ATC_AC781x_FOC_Porting_Guide_CH.pdf》.

          Hall Angle Self-learning Function
          In order to match motors of different types, ATC Demo software includes Hall angle self-learning function,which can detect automatically the corresponding motor angles of the Hall in each state.
          Set the variable of g_startHallAngleCal to 1,  the Hall angle self-learning function just can be acted. After that, the angles of each states will be saved in g_InitAngleCal[7]. Then add 30 degree to each angle in the g_InitAngleCal[7], and then fill them in _hallAngle_degree_120[MAX_HALL_STATUS].

          The motor development board supports the development and debug of the following types of motors:

          Motor type Control mode Voltage range
          BLDC- With Hall Six step square control 12~48V
          BLDC-Without Hall Six step square control(using counter emf ) 12~48V
          PMSM-With Hall FOC 12~48V
          PMSM-Without Hall FOC + SMO 12~48V
