Introduction to the EVM
The DRV8833CEVM is a complete solution for evaluating the DRV8833C stepper controller. It includes an
MSP430G2553 MCU and the firmware necessary to control the DRV8833C. Power is provided externally,
up to 10.8 V.
The Spy-Bi-Wire interface (J2) is provided to allow evaluation of user code.
The motor can be controlled by three press buttons and five jumpers on the boards. The following list
provides the functions of DRV8833C EVM:
• START/STOP, SPEED UP, SPEED DOWN buttons
• DIRection control for motor jumper
• FULL/HALF step configuration jumper
• nSLEEP configuration jumper
• Chopping current configuration jumpers
2.1
Connectors
For the EVM, a single power supply is necessary. An LDO linear regulator has been placed on the EVM to
power the MCU. Maximum recommended VM for the EVM should be 10.8 V. See the DRV8833C
datasheet (SLVSCP9) for the complete voltage range information of the DRV8833C. When the power
supply is connected to the board, a green STATUS LED (D1) on the left of the board begins blinking.
Power for the DRV8833CEVM is available through connector J8, located on the bottom right of the EVM
as shown in Figure 3.
The motor connections are provided through connectors J5 and J6 on the right of the EVM.

START/STOP: Push the button to start or stop the motor. Starts the motor with the starting speed (100
pps at full micro-step, 200 pps at half micro-step). Stops the motor from current speed to zero with internal
fixed deceleration rate (200 pps at full micro-step, 400 pps at half micro-step). If the speed of the stepper
is less than stopping speed, the MCU will cut off the pulse-width modulation (PWM) input and stop the
stepper immediately.
SPEED UP: Push and hold to speed up the motor with internal fixed linear acceleration rate (200 pps at
full micro-step, 400 pps at half micro-step). Limited to the MAX speed by software (1000 pps at full microstep, 2000 pps at half micro-step).

SPEED DOWN: Push and hold for speed down the motor with internal fixed linear deceleration rate (the
same as acceleration rate). Limited to the MIN speed by software (100 pps at full micro-step, 200 pps at
half micro-step).
DIR: Change the direction of the stepper, can be changed as the motor is spinning, but may cause the
motor to stall.

Operating the EVM
The DRV8833CEVM operates without the need of a GUI. After the power supply and motor is connected
to the board, the motor will spin up by pressing the START/STOP button. The speed of the motor can be
increased by pressing the SPEED UP button and can be decreased by pressing the SPEED DOWN
button. The direction will be changed by removing or connecting the shunt on the DIR jumper. Leaving the
FULL/HALF jumper open, puts the motor into half-step mode. Keeping the FULL/HALF closed places the
motor full-step mode. Remove the shunt on nSLEEP jumper to put the DRV8833C in sleep mode. The
chopping current of the EVM can be modified by adding or removing the shunts on J1 and J3 which will
change the value of the sense resistor.
