Digital outputs

Post by PaulM »

As a newcomer to this technology, I am trying to understand how I might use the digital outputs on a 1216 logger.
It seems this is not possible using picolog6 - or at least I can find no reference to the facility on the picolog6 screen although there is reference in https://www.picotech.com/library/data-l ... r-software which states:
PicoLog 6 alarms can also trigger a digital output on devices with supporting hardware, such as the PicoLog 1000 Series
Is a 1216 part of the 1000 series? I would have thought so! But perhaps I am being naive.
If it's necessary to utilise the SDK software, is there any reasonably clear and precise explanation of how this is done?
Thank you....

OK. I finally found the answer to my own question by exploring the alarm tab and looking at the same things I had already looked at a few times over.

I was distracted by my wish to be able to set up a digital output for examlpe with a time frame to repeatedly initiate an event rather than in response to a monitored condition.

However, I remain curious as to how to control the PWM output which I do not have an immediate use for - but may well find it useful for future projects if it is accessible.

Does anyone have anyone please have any recommendations for beginners instructions as to how to incorporate using the SDK?
I am familiar with using Basic with microprocessors but have never got so far as using C++

Thanks...

Hi Paul,

To answer your curiosity, the PWM in the PicoLog1216 has a duty cycle that is adjustable from 0% to 100% in 1% steps, during setup, but the duty cycle can’t be altered once it is in operation.

To answer your question regarding getting started using the SDK, we do have Basic.Net examples non Github, and examples using Visual Basic for Applications that run in Excel, however, due to workloads, these haven't been updated in years, and we just don't have the resources to support them (I'm aware of at least one problem in the VBA example that we have on Github).
So, my advice (if you don't want to deal with the learning curve of moving to C++ from Basic) would be to look at our Python implementations. Python is simpler to get your head around, has many free resources for it, and will have the benefit of a familiar fast-track method that you can use to get up to speed, i.e. it lends itself very well to intuitive interpreters (like Basic did) which you can easily find online and use, also its libraries are pretty extensive (and also free).

Regards,

Thanks Gerry.
I am now studying C++
It's a bit of a monster - but something to keep the ageing grey matter being challenged!
