Multi-ADC (Analog Digital Changer) for Amiga, Pegasos and Amithlon
Here is an electronic diagram and a small test program for my six channel multi analog digital changer (download, 87 KB).
Characteristics of the ADC chip:
- Six measuring channels
- Programmable for unipolar (from 0V to +5V) and bipolar (-5V to +5V) measurements per channel
- Programmable reversal of the measurement polarity (only with bipolar)
- 12 bits resolution per channel
- programmable stand-by mode of the ADC
The following must be installed:
- rexxtricks
- tritonrexx
- triton.library
- rexxserdev
The following ENV variables should be inserted in the "ENVARC:" designation:
- Analog-device = serial device
- Analog-unit = serial unit
- Analog-Volt = maximal voltage reachable at the measurement entrances (normally "5")
Important:
The hardware (MultiADC) is fixed to a data rate of 15000 baud. If this data rate is changed on the computer there won't be any correct transfer of information.
The passive building elements (condensers and resistors) must be built exactly in accordance with the instructions. Deviating values in Ohms or Farad lead to an incorrect function of the MultiADCs.
All building elements are in CMOS technology. So one must wear an anti-static armband so as not to disturb the connection pins. Through this one is able to make it reliable.
With one's own, self-provided program one must pay attention to the programming of the chip LTC1293, since this deviates with the available hardware something from the data in the PDF document from this chip.
Example:
For a logical 1 at the data entrance of the LTC1293 chip one programs in ARexx "call serwrite(ser,'11111111'B,1)" and for a logical 0 it would be "call serwrite(ser,'00000000'B,1)." (snx) (Translation: dm)

Heise April Fools: MP3 with MOD Tracker Modification
In their first report of the day Heise.de offers Further MP3 Efficiency Leap. The article describes how, comparably to the idea that was earlier used in the "Tracker-Zeit," similar pattern inside an MP3 song may be re-used.
Quote (translated): "The idea for dMP3 is a quasi-reminiscence of the 16 Bit Era: because without good software instruments MIDI simply only produces sad beeps, the Tracker/MOD scene, which reached its high points in the 16 Bit Era, has reinvented itself."
Update: (1st April, 2004, 5:39 pm, snx)
Original title of the report recreated, after the April Fools joke was camouflaged this morning on account of readers' wishes. (snx) (Translation: dm)

Emulator: MaxUAE 0.8.25 including tool bundle released
The Amiga emulator MaxUAE for Mac OS X has been put online in
version 0.8.25. Different to Richard
Drummond's announcement on his homepage there still is no SCSI
support within this version. But there will be a bugfix
release available soon. With the pre-version the SCSI
emulation works already.
At the MaxUAE website there is also version 1.0 of a bundle of
tools available.
These tools simplify the usage of
Drummond's UAE port and consist of the following parts:
UAE Config Creator (to create configurations using a GUI), UAE
Dropper, UAE Game Loader (easy assignment of ADFs and choice
of the system) and the UAE Virtual Disk Assistant (creation of
DD/HD Floppies and
hard disk images).

Picture converter: SplitMultiImage 1.1
"SplitMultiImage" splits files that contain several pictures (e.g. multi-page TIFF fax files) into the individual pictures.
The new version fixes a bug which caused SplitMultiImage to save multiple copies of the same image for files containing only one image, when the datatype does not support PDTA_GetNumPictures.

SplitMultiImage 1.0 released
The first version of a new tool called SplitMultiImage is now available.
Starting with AmigaOS 3.5, the picture.datatype documentation defined two
new tags (PDTA_GetNumPictures and PDTA_WhichPicture), which allowed
subclasses to return different images from the same file, where relevant.
For example, TIFF image files often contain more than one image, and
WarpTIFF.datatype is able to decode any of those images on request,
returning any of the images to the application.
Unfortunately, not many applications have made use of this feature (in
fact, at the time of writing, Oliver is not aware of any) and can therefore read
only the first image in a file. After requests from WarpTIFF users wanting
to know of software capable of reading all the pages in multi-page TIFF fax
files, Oliver decided to write SplitMultiImage. Although not as nice as
Multiview having this capability built-in, SplitMultiImage at least allows
all the images to be viewed by extracting all the images from a file and
saving them separately as IFF-ILBM files.
SplitMultiImage is not restricted to TIFF files - in theory, it will work
with any datatypes supporting the new tags and for image formats that can
contain multiple images.

MorphOS: New, unnamed picture viewer
Kiero programmed a new so far unnamed picture viewer (165 KB). As soon as it has a name it will be available on Aminet.
Features:
- Easy disk navigation with mouse or keyboard.
- Images loaded with datatypes or builtin routines (for JPEG and SunRaster)
- MUI GUI
- Image processing options like color balance/resizing (same algos like in ACDSee)/levels adjustment/etc...
- Saving in JPEG or PNG (with or without alpha channel)
- Loading/displaying images with alphachannel (background is visible).
- Scaling of graphics during display (with optional bilinear filtering).
- Drag&drop support for files/directories.
- Fullscreen mode and a possibility to minimize GUI elements.
- It's slow;)
The following MUI-classes are needed:
Better Balance
Better String (Aminet)
