Audio Capacitive Touch BoosterPack - Ti Processor Wiki
Meet the Audio Capacitive Touch BoosterPack (ACTBP) – a plug-in board for the
LaunchPad development kit and MSP430™ Value Line Microcontrollers. This kit
offers a complete reference design for capacitive touch solutions, using the capacitive
touch I/O ports of select MSP430 Value Line Microcontrollers. This reference design
will allow you to easily control the
C5000™ ultra-low-power digital
signal processor (DSP) using TI’s
MSP430 Microcontroller for crystal
clear playback and record of MP3s.
Contents of this BoosterPack:
• Audio Capacitive Touch BoosterPack Board
• MicroSD card pre-programmed
with DSP function code
• Mini-USB cable
• Initial demo headset with integrated microphone
• MSP430G2553 Value Line Microcontroller pre-programmed with

Installation
1. Install the included, pre-programmed MSP430G2553 Value Line Microcontroller on
your LaunchPad after removing the previous MSP430™ Value Line Microcontroller.
2.
Jumper settings:
• LaunchPad jumpers:
– J5 – P1.0 and P1.6 must be removed
– J3 – TXD and RXD must be removed
• BoosterPack jumpers: Factory settings will work for normal operation
3. Mount the ACTBP on the LaunchPad so that both USB ports on each board point
up. Connect the included USB cable to the USB mini connector on the ACTBP and
the other end to a USB port on your computer to power up the system.

“Audio Capacitive Touch BoosterPack” should be displayed on the OLED display.
5. “Touch CENTER LED to agree to be bound by the ACTBP license” should be displayed next. Please refer to the separate document found in the box entitled “Audio
Capacitive Touch BoosterPack (ACTBP) Software Development Kit License Agreement” for more details. Click on the lighted CENTER LED to continue. (Message will
not be displayed on next power up if user accepts agreement.)
Note: Make sure to set the board on a table-top rather than hold it in your hand which
will interfere with the capacitive touch operation.

Music Player Demo
The Audio Capacitive Touch BoosterPack includes a pre-programmed microSD card
with a directory of music files to experience crystal-clear audio and simple music playerlike commands using the capacitive touch interface. Give it a try! (For detailed features,
see the following tables.)
• Plug the headphones found within the box into the headphone jack on the ACTBP board.
• Scroll through the directory by moving your finger clock-wise or counter-clockwise
on the capacitive touch. You should see three example directories labeled “Music”,
“Podcasts”, and “RecDir” respectively. This is the “Browse Directory” mode.
• Press CENTER once to select the directory. Press UP to go back to the root directory.
• Scroll to your desired audio file by moving your finger clock-wise or counter-clockwise on the capacitive touch. This is the “Browse File” mode.
• Press CENTER once to begin playback.
• With the below tables as a guide, browse the sample music and podcast files. Try
out the record function as well by holding on DOWN for a couple seconds.
• For the best audio experience, plug in your favorite headphones (including your cell
phone headphones) or speakers and see what the C5000™ DSP can really do.
• To add your own music and files to the Audio Capacitive Touch BoosterPack,
double-tap on DOWN when you are in “Browse Directory/Browse File” mode. “USB
Mass Storage Device Enabled” will be displayed. On your connected computer, you
should see the BoosterPack listed as a new drive. Simply copy your files and music
over to the new drive in selected folder. Double-tap DOWN again to resume browsing directories. Note: Do not delete the “bootimg.bin” file from the provided microSD
card; the ACTBP won’t work without the file.
