Product Specification

Port Description

Motor driver PWM signals

CRUVI interface signals are utilized to drive the half bridge PWM motor driver signals. They are logical connected to prevent driving the high and low simultanously:

M_PWM_AH <= '1' when ((A3_N='1') and (A1_P ='0')) else '0';
M_PWM_AL <= '1' when ((A1_P='1') and (A3_N ='0')) else '0';

M_PWM_BH <= '1' when ((A3_P='1') and (A0_P ='0')) else '0';
M_PWM_BL <= '1' when ((A0_P='1') and (A3_P ='0')) else '0';

M_PWM_CH <= '1' when ((A1_N='1') and (A2_N ='0')) else '0';
M_PWM_CL <= '1' when ((A2_N='1') and (A1_N ='0')) else '0';

M_PWM_DH <= '1' when ((A0_N='1') and (A2_P ='0')) else '0';
M_PWM_DL <= '1' when ((A2_P='1') and (A0_N ='0')) else '0';

Motor disable

The M_DISABLE signal set via push button S1 is used to disable all 4 motor drivers. This signal is logical or to the PWM enable signal from B1_P on the CRUVI connector.

M_DISABLE_OUT <= M_DISABLE or not B1_P;

M_DISABLE_A_D <= M_DISABLE_OUT;
M_DISABLE_B_D <= M_DISABLE_OUT;
M_DISABLE_C_D <= M_DISABLE_OUT;
M_DISABLE_D_D <= M_DISABLE_OUT;

The motor disable signal is also forwarded to the CRUVI interface:
A5_P <= M_DISABLE;

Sensor/Encoder, Back EMF

Sensor signals are forwarded to the CRUVI interface:

B2_P <= ENC_A;
B2_N <= ENC_B;
B3_P <= ENC_I;

B3_N <= M_BEMF_B_D;
B4_N <= M_BEMF_A_D;
B4_P <= M_BEMF_C_D;

Current and voltage measurement

Data signals from the 3 ADCs are forwarded to the CRUVI interface:
B5_N <= SD_V;
B5_P <= SD_IA;
A4_P <= SD_IB;

The corresponding clock signals are derived from the CRUVI interface signal B1_N:
SCLK_V_A <= B1_N;
SCLK_A <= B1_N;

Button

Motor disable button

S1 is utilized to switch the motor control on/off. The button is debounced. On press it switches the state of M_DISABLE signal and sets the corresponding LED status.

User Button

User button S2 is forwarded to the CRUVI interface signal A4_N:
A4_N <= BUTTON1;

LEDs

Status LED

The LED D1 is utilized for board status information in the following way:

USR LED

User LED D2 is controlled via the CRUVI signal B0_N:  
LED0 <= B0_N;
