MSP430 Control and Firmware
Figure 15. Measuring the DRV2603 Output with a Digital Low-pass Filter
An analog 1st order, low-pass, RC filter can also be used; however, care must be taken not to use a filter
impedance that is too low. Low filter impedance can affect the back-EMF of the actuator and interfere with
the auto-resonance detection algorithm. See the recommend values in Figure 16.

5 MSP430 Control and Firmware
The DRV2603EVM-CT is controlled by a programmable MSP430. This section contains information for
programming and controlling the board using the MSP430.
5.1 Additional Hardware Modes
Additional modes are available on the DRV2603EVM-CT that provide increased board control and
functionality. The additional modes are not available in “demo” mode, but can be access by switching to
“binary counting mode”. In “binary counting mode” the mode LEDs count in binary (32 modes) rather than
in “demo” mode format (only 6 modes including off).
5.1.1 Enter Binary Counting Mode
To enter “binary counting mode” and access the additional modes:
1. Press and hold the increment mode button (“+”) for approximately 3 seconds.
2. Release the button when the actuator buzzes and the mode LEDs flash.
3. Select from the “binary counting modes” using the “+” and “-“ buttons.
All modes, including “demo” modes, are available in binary counting mode, see Table 3 for a description.
5.1.2 Exit Binary Counting Mode
To exit “binary counting mode” and return to “demo” mode:
1. Press and hold the decrement mode button (“-“) for approximately 3 seconds.
2. Release the button when the actuator buzzes and mode LEDs flash.
3. Select from the “demo” modes using the “+” and “-“ buttons.

MSP430 Control and Firmware
5.2 Modifying or Reprogramming the Firmware
The MSP430 firmware on the DRV2603EVM-CT can be modified or reprogrammed to create new haptic
effects or behaviors. Find the latest firmware source code and binaries on TI.com. Follow the instructions
below to modify or reprogram the DRV2603EVM-CT.
1. Purchase one of the following MSP430G2553 compatible programmers:
• EZ430-F2013 (recommended)
• MSP-EXP430G2 (recommended) - requires the additional purchase of a header for J4
– Digi-Key: ED8650-ND
– Mouser: 575-500201
• MSP430-FET430UIF - requires a JTAG to Spy-Bi-Wire adapter (MSP-JTAGSBW if available)
2. Download and install Code Compose Studio (CCS) or IAR Embedded Workbench IDE.
3. Download the DRV2603EVM-CT source code and binaries from TI.com.
4. Connect the programmer to an available USB port.
5. Connect the programmer to the “SBW” header on the DRV2603EVM-CT.
6. In CCS,
(a) Open the project file by selecting Project > Import Existing CCS Project.
(b) Select Browse and navigate to the DRV2603EVM-CT project folder, then press OK.
(c) Select the checkbox next to the DRV2603EVM-CT project in the “Discovered projects” window and
then press “Finish”.
(d) Before compiling, navigate to Project > Properties > Build > MSP430 Compiler > Advanced Options
> Language Options and make sure the checkbox for “Enable support for GCC extensions (--gcc)”
is checked.
7. In IAR,
(a) Create a new MSP430 project in IAR,
(b) Select the MSP430G2553 device,
(c) Copy the files in the project folder downloaded from TI.com to the new project directory.
