  1. Hi I have a Tiva C TM4C123GXL launchpad. I was wondering if the SD Card booster pack, will fit the Tiva C board? I read it had 40 pin support and had solderable jumpers. Thanks Joe

    Again you are not reading what I have written "I did not indicate that conductive thread was a viable solution," I also did not indicate to use the stainless thread. I said "If you want better resistance then sew with larger AWG wire." I was referring to sewing with copper wire, not stainless thread.

    @@rockets4kids, The OP asked about use of conductive paint/epoxy, I did not indicate that conductive thread was a viable solution, I indicated I would use conductive before I would use conductive paint. But doing a bit more research, The Adafruit web site indicates that a 3 ply stranded stainless steel thread has the following specs: Measures 0.25mm thick, 3 ply thread, 0.83 ohm per inch If you look at the AWG chart at http://www.engineersedge.com/copper_wire.htm These specs are right in line with stranded 30 AWG wire and for 1000 feet the resistance is 103.00 ohms. The 3 ply stranded stainless thread has better resistance than 30 AWG copper wire. If you want better resistance then sew with larger AWG wire. Watch some of the videos at the Adafruit web site, working with conductive thread is not as bad as one might think. Cheers Joe

    I would rather go with conductive thread and other fabric based components before I would go the conductive paint/epoxy. As mentioned, pricey, high resistance, joining standard parts to existing materials. Conductive thread, sneak your wife's sewing machine, get some cheap fabric and sew your parts on a fabric circuit board, I guess that would be an FCB. Check out Adafruit, they have lots of fabric based components. Thanks Joe

    Arduino Adapter Booster Pack for LaunchPad XL

    Very nice, I was thinking of doing this, because it is a much needed item for cross platform support. Great job. Now TI LaunchPad users can leverage many of the Arduino shields out there, until the world recognizes that the booster pack pin configuration is a better way to go. ;-) Thanks Joe

    My Attempt at the LaunchPad ZIF socket

    Thanks RodG If the female header pins would not have worked I would have gone the boosterpad pin route. Joe

    My Attempt at the LaunchPad ZIF socket

    abecedarain, Good question. The chip socket that TI uses has small round holes. The ZIF socket will not fit directly into the chip mounted on the launchpad. If you look at the pins on the ZIF socket they are wide and flat. The male pins on the female header socket are small enough to fit directly to the socket on the launchpad. Thus the two part solution is required. Thanks Joe

    My Attempt at the LaunchPad ZIF socket

    Rei Vilo, You know what they say, "Great minds think alike" Thanks Joe
  9. Hi All, I have read the other posts about the problems with attempting to unsolder the chip socket from the mps430 launchpad. Believe me I have a stack of trashed boards that have the through hole copper trace shot. I also wanted to retain the onboard 32Khz watch crystal. So digging through the parts box and trying different things I came up with the following easy to install version of the ZiIF socket install. I purchased some 10 pin female header sockets, trimmed the pins down. Purchases a few ZIF sockets, mine indicate TFXTDOL. Removed the msp430 chip, Inserted the female pin headers and inserted the ZIF socket. Concerned that the longer pins and socket would interfere with the operation of the watch crystal I downloaded the Verify_Crystal and tested the program. At first I had some issues with the crystal faulting. But after added the following line to the program. The Verify_Crystal program runs just fine. BSCCTL3 |= XCAP_3; which enables the 12.5 pF. Enclosed are some pics. Easy Peasy

    What are you working on today/this week?

    Hi, new to MSP430, been reading MSP430 Microcontroller Basics by John Davies, up to Chapter 4. Nice book to go along with the user guides. Dusted off my EZ430 Chronos watch. Looks like it it time for a project. Joe
