Minor update:
- Access to the RevPi core temperature via
.core.temperature - Troubleshooting when using
simulator=Trueon instantiation - Improved performance during instantiation
Events with the mainloop()
We’re testing the mainloop() here. Continue reading “Events with the mainloop()”
Driver for Virtual Device out of piCtory
We use RevPiModIODriver() to develop a driver for a virtual device in piCtory. Continue reading “Driver for Virtual Device out of piCtory”
Version 1.0.2
Minor Update:
- Access to the RevPi core temperature via
.devices.core.temperature - Troubleshooting when using
simulator=Trueon instantiation
Version 2.0.2
Version 2.0.2 is stable!
After many test hours and a few minor improvements, RevPiModIO 2 is now FINAL! 😀
INFOS about the new version will be available soon!
In addition to the new, simplified syntax, we have added a new parameter “delay” for .reg_event (...) and the new function .reg_timerevent (...).
Version 1.0.0 – final!
After many months of development and new features, we have now released the final version!
RevPiModIO Version 1
In addition to a few refinements and a bugfix with the byte order of the default values, this version is worthy to get the version number 1 😀
This version is still maintained, but we have learned by the development and the version 2 is in the starting holes! Look at the new syntax, which also offers many advantages in an interactive Python shell on the RevPi!
Cyclic with little python code
This example introduces you to the cyclic programming with RevPiModIO and the cycleloop(...)! The program also uses the handlesignalend(…) function to catch the “end of program” signal and exit the program cleanly. Continue reading “Cyclic with little python code”
Everyone wants digital – we do analog!
We have the analog module AIO on our Revolution Pi! Continue reading “Everyone wants digital – we do analog!”
Version 0.16.1 – analog module
There is a new update for the use of the analog module AIO.
- IOs of the analog module are instantiated with “signed=True”. This activates the value calculation with a sign. Otherwise, the value -1 would be 65535 and negative values would not be allowed in assignments.
Version 0.16.0 – Less Python, more PLC
With this update you can program more PLC with less Python code.
We introduce: cycleloop(cyclefunction)
- The new
cycleloopreads the inputs, executes the passed function and writes the outputs in the set cycle time “auto_refresh“.
If you call.devices.cycleloop(cyclefunction)in your program, it blocks at this point and cyclically executes the function “cyclefuntkion“. To this function an instance of class RevPiCycletools() is passed, which includes tools such as clock markers, edge flags, or timer objects. - New function for easy exit a cyclic or event-based program
.handlesignalend(cleanupfunc) - If the set update rate of the process image (
auto_refresh) is exceeded, you will get a warning – each time! auto_refreshvalues greater than 1000 milliseconds could produce errors with.wait(...)andmainloop()- Module closes faster with
.cleanup()or.exit() - The module no longer blocks exit when using the Python shell’s interactive mode
