StagView 1.7.2 ( 13/08/23) New software for stag programmers Stag PP39 , Stag PP42 , Stag PP41, Stag PPZ

http://baddinsbits.altervista.org/files/stag/devsup.txt (13/08/23) Stag programmer device support list v2.5

update StagView 1.7.2 : story: : with a 39M101A module rev 3.1 and a more modern Linux distribution which would not run the Linux version of StagView because of changes to one of the libraries it uses.
took some time modifying the code to compile it with the later version of the tvision library that it requires. When I had something that he could try I sent it to him and found that the firmware was so old that it had a different format for the revision number and StagView thought it was revision 0.3 and no devices could be selected !

added code for the new revision number format and ran my tests to find the devices supported by rev 3.1.

also found more errors in the module .DAT files which have been there for 20 years or more.

StagView new release can perform checking of the file selected for "Load from File" to see if it is of the correct type.
It only checks the start of the file but it should prevent the program and the programmer from locking up if the wrong file is selected.
there is also now the "Disconnect" option which may be useful when there is more than one programmer connected to a PC.
The other changes were to detect the parallel port type when used on MS-DOS to prevent lockups if the type if configured incorrectly.

StagView allows the display of up to 10 ports available for use in the Connect dialog, including USB serial devices for Linux which were difficult to use before. There is a logging option in Options/other for anyone interested in the data sent and received; the software has been tested with USB serial cables.

This new version of StagView fixes some user interface issues and the "Programmer" menu which is no longer needed is removed.
The device selection dialog also displays if a device entry is supported by the programmer or is an alias of another device. Stag added other device types to the .DAT files with identical device codes and those devices are shown as aliases of the first device in the .DAT file with that code

http://baddinsbits.altervista.org/testfirm.html Device programmer test firmware Stag PP38/39, Stag PP40/41/42, GP Industrial Electronics XP640 ; pp4x_1-0.zip which hopefully will detect problems that the standard firmware doesn't. The interface with the display and keypad is very basic but if it gets that far the programmer is probably working ok.

calibration procedure for Stag PP40 series the self test routines are not in the standard modules but in a special module named "CAT40"
It also explains why the key presses for the PP39 self-test do not work on the PP42

Stag COM1 release 8 Software for use with Stag PP42 programmer connected to the parallel port ( ZIP Archive - 185Kb)

This StagCom rel. 8 works in parallel mode with a 486 pc running MS-DOS. No other release works in parallel mode, the parallel port hardware must use open-collector/open-drain control outputs as they are used to send data back to the pc and a more faster modern pc will not work because of the critical timing in their parallel protocol.

Please note that the drawings were probably reduced from A0 or A1 on a photocopier and some were copies already and so are almost unreadable on paper but the parts lists shows the IC types which helps a lot. It doesn't have the drawings for the Serial/Parallel/RAM board
