DRV8711: initialization worked fine but signals on STEP Pin do not get the stepper motor to move

Part Number:DRV8711

Hello everyone,

I very interested in the DRV8711 and especially its use as stepper motor driver.

I developed my own board for a cnc maschine. I could initialize the DRV8711 via SPI with the setup I expect will be the correct one for my motors.

An Adruino Uno board sends the Step and the directions signals as well to control the control the motors

until now I cannot get the stepper motors to move one step.

here are the data I send via SPI for the initialization of the DRV8711:

//Write register
uint8_t W_CTRL_Reg_Data1 = 0x0D;
uint8_t W_CTRL_Reg_Data2 = 0x41;
uint8_t W_TORQUE_Reg_Data1 = 0x13;
uint8_t W_TORQUE_Reg_Data2 = 0xFF;
uint8_t W_OFF_Reg_Data1 = 0x20;
uint8_t W_OFF_Reg_Data2 = 0x30;
uint8_t W_BLANK_Reg_Data1 = 0x31;
uint8_t W_BLANK_Reg_Data2 = 0x80;
uint8_t W_DECAY_Reg_Data1 = 0x41;
uint8_t W_DECAY_Reg_Data2 = 0x10;
uint8_t W_STALL_Reg_Data1 = 0x50;
uint8_t W_STALL_Reg_Data2 = 0x40;
uint8_t W_DRIVE_Reg_Data1 = 0x6A;
uint8_t W_DRIVE_Reg_Data2 = 0x59;

can you please help me!!

P.S: how do I proceed to send you the schematic in private?
