Reuse, Interoperability, Portability, Code Complexity - New Survey
by Brandon Shirley 07 Apr '16

07 Apr '16

Dear AMSAT community members, I'm Brandon Shirley, I am conducting a set of surveys about space systems and software development for my PhD research at Utah State University. I really need your participation. There is a chance to win some gift cards. Please see below for more information and the link to take the survey. The survey should only take about 10 minutes. Reading this wordy email will probably take more time than actually taking the survey. Thanks. I sent you this email because I thought you might have relevant experience and greatly need your participation. The second part of the survey has background questions that will give context to your answers. Try to fill the background out the same way if you take more than one of the surveys. You can you use the link below to access the Reuse, Interoperability, Portability, Code Complexity Survey. https://usu.co1.qualtrics.com/SE/?SID=SV_79TOgGac3B4Z77f Answer as many of the questions as you want and as much of each question as you want, partial surveys may still be very helpful. At the end of this survey, you will be redirected to a webpage that asks for an email address. You must enter a valid email address to be considered for survey drawings or the overall survey set drawing We are currently on the 5th survey, Reuse, Interoperability, Portability, Code Complexity. You have a chance at receiving a gift card for participating in this survey as well as a chance at receiving a gift card for your overall participation in the entire survey set. There will be 2 winners of $25 gift cards for each survey and 2 winners of $200 gift cards for the survey set. The surveys are as follows and will be distributed in the following order: (participate as you see fit) SISDPA : Core Concepts SISDPA : Development Preferences SISDPA : Open Systems Architecture and Modularity SISDPA : Security SISDPA : Reuse, Interoperability, Portability, Code Complexity <========= We are here ========= SISDPA : Network V/R, Brandon Shirley b.l.s(a)aggiemail.usu.edu See http://brandon.bluezone.usu.edu/Files/LOISpaceSoftwareAttitudes_Final.pdf for the Letter of Intent (LOI) that explains your role as a participant should you choose to participate. This is a legitimate request for you participation, if you have any questions about the validity of this email you may refer to the Letter of Intent, contact Brandon Shirley via email at b.l.s(a)aggiemail.usu.edu, or contact Utah State University's Internal Review Board administrator at (435) 797 - 0567 or email irb(a)usu.edu.

help with pic programming on LVB tracker
by Ed K9EK 06 Apr '16

06 Apr '16

Hi, all: Several years ago I bought the G6LVB tracker board and finally got around to building it. All went well until trying to program the pic. I followed Gould Smith's instructions (would have been impossible without them; thanks Gould). Things seem to go OK until it tries to run the picprog software script. It starts, then simply stops at the second line "reading hex file...". It drops to the next line and there it sits (blank with flashing cursor). Hardware: using an XP laptop with a new StarTech FTDI USB-to-serial converter. Could not get the converter to be recognized by either of two WIN 10 laptops, but the old XP machine is fine with it. I have tried all combinations of power on, off, when to plug in, boot up, etc. Same result every time. I did see some cryptic on-line messages of difficulties getting the script to run on anything except an ancient machine with a real live RS232 interface. Surely there is another way.... Humm. Does anyone have any idea on how to make this thing run? Thanks! Ed K9EK EL98
