ADT-200A - updating firmware - the bare metal way

Hans, HB9CBU, has created a new firmware version 1.36e for the ADT-200A . This release has a few very much needed updates I talked about with Hans - one of them making it possible to create a Rig file for CW Skimmer (which I am working on now).

Unfortunately, updating the firmware turned out to not be an easy task. As I am on Mac OS X I looked for an easy way to talk to the serial device of the ADT-200A. The ADT-200A is connected via USB using the internal USB-to-Serial converter in the TRX. As such the TRX is recognized as device "/dev/cu.usbserial-1004079" on my Mac.

After a bit of fiddling I came up with the following little Python script:

'''

import serial

 def update
    ser = serial.Serial( '/dev/cu.usbserial-1004079', 9600 )
    ser.write( '$DNL?' )
    ser.write( '\r' )
    ser.read()
    p0 = open("/var/data/frgo/Funk/ADT-200a/Firmware/Hardware/1.36e/136e_p0.dat", "r")
    data = p0.read()
    ser.write( data )
    p0.close()

def main():
    update()

if __name__ == '__main__':
    main()


This script requires PySerial . If you want to use this script you have to adapt the serial device to match your ADT-200A and also the path to the firmware file. You should be able to find the relevant places in the script above - if not, this script is not meant for you ;-)

SLIME, Lisp, Editing - the lost slime-close-parens-at-point

Once upon a time there was a rich SLIME version that had all bateries included in a few files. Now this old, old version is long gone. The Powers Of SLIME deleted the function slime-close-parens-at-point whose use and benefit is described in this blog post of Bill Clementson . For those requiring this exact feature here's the original code of that function: (setq slime-close-parens-limit 16) (defun slime-close-parens-at-point () "Close parenthesis at point to complete the top-level-form. Simply inserts ')' characters at point until `beginning-of-defun' and `end-of-defun' execute without errors, or `slime-close-parens-limit' is exceeded." (interactive) (loop for i from 1 to slime-close-parens-limit until (save-excursion (slime-beginning-of-defun) (ignore-errors (slime-end-of-defun) t)) do (insert ")"))) In addition to putting this in my .emacs file I have also the following line in it: (define-key slime-mode-map (kbd "...

Compiling ACE+TAO on Mac OS X

So, what's ACE+TAO? It's big, it's complex, it's middleware! See more info at http://www.cs.wustl.edu/~schmidt/ACE.html and at http://www.cs.wustl.edu/~schmidt/TAO.html . In trying to compile ACE 5.7.5 and TAO 1.7.5 on my Mac OS X 10.5.8 system I encountered some strange error messages while linking. These were duplicate symbol errors I couldn't really track down to their root cause but was able to find simple cures. For those poor souls also hitting those faults the following list of changes may help: File $ACE_ROOT/ace/Based_Pointer_Repository.h File $ACE_ROOT/ace/Obstack.h Re 1. : File $ACE_ROOT/ace/Based_Pointer_Repository.h I had to comment out the ACE_SINGLE_DECLARATION on lines 82 to 84: /* - frgo, 2010-01-03 /// Declare a process wide singleton ACE_SINGLETON_DECLARE (ACE_Singleton, ACE_Based_Pointer_Repository, ACE_SYNCH_RW_MUTEX) */ Re 2. : File $ACE_ROOT/ace/Obstack.h I had to comment out the ACE_SINGLE_DE...

The ADT-200A SDR TRX in practice ... A talk @ DARC P31

Bild
Dr YLs es OMs ! On March 23rd I gave a presentation of the features of the ADT-200A Software Defined Transceiver at the local Amateur Radio Club, DARC e.V. OV Ermstal DOK P31 .  The presentation focused on practical aspects of actually using the ADT-200A. We had about 15 radio amateurs (only OMs, unfortunately, HI) in the room and what was planned as a 1 hour talk turned into a 2 hour session ... We had fun using the TRX  and two CW QSOs have been completed with RA9XU - about 3000 km with just 50 watts into a dipole on 40 meters.  The exceptional performance of this TRX created some "wow" and "ah" effects -  it was a pleasure listening to CW signals with just 150 Hz bandwidth - the digital CW filters are going down to 50 Hz (we used 150 Hz for the QSOs) and there's no signal degradation whatsoever. Really sweet  ... One OM asked if I would by another TRX if I had all the money I can imagine - I just answered "Why should I ?" ... Fo...
