[DSP-10] X101 crystal soldering

[Roger Hayward]

Just a quick note before heading off to the signal factory for the day.

Note that the PC software must be run on a DOS machine.  Unfortunately, at
this time, this means a box running DOS, not windows.  Example:  Windows 98,
with DOS booted PRIOR to launching Windows 98 works.  Launching a DOS box
from 98, 2000, XP, does NOT work.  The UART's interrupt service routine
needs to not get trapped by windows.

Off to decode some signals.

Roger,

Thanks. I did not think it made sense to do that, but I wanted to make sure.

I finally got back to spending some time on the DSP10. I have been enjoying 
it. My main board is finished and tested. Everything looks good so far. I am

getting ready to wire up the DSP board.

I have been testing the DSP board (EZKIT Lite) stand alone. I can get all of

the example programs working and now I am trying to test it out with the PC 
program (UHFA.EXE) like Bob explains in the QST article #2.  I am using the 
ADI EZKIT Lite loader. I can get the DSP program loaded onto the ezkit using

that program. However, it must run under windows. Then I reboot the PC and 
startup in DOS (using a boot disk). When the program first comes up it does 
not seem to allow any control through all of the keyboard functions. Most of

the controls do not do anything. I cannot even get it to toggle between 
transmit and receive mode.

According to the QST article I should be able to run the audio processing on

an input into the ADC jack. However, I cannot get normal control from the PC

software.

Have you heard about anything like this? I read through all of the reflector

postings and did not see anything.

Well, I think it is time for bed. I will push forward again tomorrow night.

Take care!

Dave
