MSP430 Firmware

The MSP430 firmware on the DRV2605LEVM-CT can be modified or reprogrammed to create new haptic
effects or behaviors. Find the latest firmware source code and binaries on

www.ti.com

. Follow these

instructions to modify or reprogram the DRV2605LEVM-CT:

1. Purchase one of the following MSP430G2553 compatible programmers:

•

MSP430 LaunchPad (MSP-EXP430G2) – requires the additional purchase of a header for J4
(recommended)

–

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 DRV2605LEVM-CT source code and binaries from

www.ti.com

.

4. Connect the programmer to an available USB port.

5. Connect the programmer to the “SBW” header on the DRV2605LEVM-CT.

6. In CCS,

(a) Open the project file by selecting Project

→

Import Existing CCS Project.

(b) Select Browse and navigate to the DRV2605LEVM-CT project folder, then press OK.

(c) Select the checkbox next to the DRV2605LEVM-CT project in the “Discovered projects” window,

and then press Finish.

(d) Before compiling, navigate to Project

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

www.ti.com

to the new project directory
