MicroDAQ toolbox for Scilab can be used to develop advanced data
acquisitions applications. Toolbox lets you make a variety of measurements
directly from Scilab without the need to convert the data or import from
other software. Software includes functions for controlling analog inputs,
analog outputs, digital I/O (quadrature encoders, PWM). You can visualize
and analyze data, automate measurements, create wireless measurement
applications and a lot more with MicroDAQ toolbox for Scilab.
MicroDAQ toolbox for Scilab features automatic code generation from Xcos
diagram.
The user can build block diagram and generate DSP application in minutes
without
having in-depth knowledge about hardware. Generated DSP application can be
loaded on MicroDAQ with WiFi or Ethernet automatically. Toolbox generates
periodic applications with a frequency defined by the user. Depending on the
model complexity and used blocks, a generated application can be executed with
up to 200kHz on MicroDAQ DSP core giving user possibility to create advanced
digital signal processing, control, and measurement application.
MicroDAQ toolbox for Scilab allows easy integration of custom C/C++ code making
Xcos model development more flexible. The user can automatically generate Xcos
blocks which executes custom C/C++ code. The user can optimize some parts of
Xcos model by replacing standard Xcos block with a custom block which contains
optimized C code for faster execution.
MicroDAQ toolbox for Scilab provides tools for target execution profiling.
This tool gives a clear answer about model execution times which in a real-time
application is very crucial.
Release notes:
Major changes:
- Scilab 5.5.2 and Scilab 6.0.2 full support with code generation
- No need to install SYS/BIOS and XDCTools - only DSP compiler required
- Firmware 2.2 is required
Data acqisition and signal generation:
- Additional object-like API for AI/AO (mdaqAITask, mdaqAOTask)
- Triggers for start acquisition or signal generation added
- Start data acquisition or signal generation when DIO state is present
- Start data acquisition or signal generation when one or more
DIO states are present - DIO pattern
- Start data acquisition or signal generation when quadrature/edge counter
is lower/greater then value
- Start data acquisition or signal generation when when DSP application
is started - AI/AO synchronization with DSP
- mdaqAIScanTrigger, mdaqAOScanTrigger added
- mdaqAIScanRead, mdaqAIScanStart added
- mdaqAOScanIsDone, mdaqAOScanWait allows to check if signal generation
is comleted or wait until is comleted (mdaqAOScanWait)
- mdaqAIScanInit and mdaqAOScanInit() returns an object
- mdaqAIScanInit and mdaqAOScanInit() can be called with object
instead of multiple arguments
- data acquisition object contains custom channel name
- mdaqEncoderInit supports additional modes (dir count, up count, down count)
- mdaqDIOWrite, mdaqDIORead accepts vector of digital values
DSP managment:
- mdaqDSPInit added - loads and configures DSP executable with duration
and rate arguments
- mdaqDSPIsDone, mdaqDSPWait allows to check if signal generation is comleted
or wait until is comleted (mdaqAOScanWait)
- Additional object-like API for DSP managment (mdaqDSPTask)
Xcos improvements:
- optimized SIGNAL block allows read DSP data with higher rates
- duration and rate printed when model is loaded on DSP
Xcos blocks:
- MEM read block can load CSV file
- Profiler block added - allows to measure execution time of the model live
- Encoder block supports additional modes (dir count, up count, down count)
Other:
- mdaqDSPSignalRead is obsolete use mdaqDSPRead instead
- PWM ZVSFB example
