PWM control not 5VDC on DIO Module

Post by fandi »

Dear Kunbus Forums,

Our team have trouble with the DIO PWM feature right now,
We have been following the guides on PWM here:

Revolution Pi : Tutorial EN 15 - PWM on the RevPi DIO
https://www.youtube.com/watch?v=QGntXTGWo7k

But the output is currently up to 12V, it's not the same as in the video.

Currently on test is using:
+ RevPi Connect SE 8GB
+ RevPi DIO
+ Connected to a 12VDC Power Supply

Are we missing some steps? or is there any solutions to this?
Since we can't find a module that uses PWM control up to 12VDC.

Thank you,

Best Regards,

Hi, I have probably set the duty cycle on the oscilloscope incorrectly to one tenth. That's why it doesn't show 24 volts but a little over 2 volts. Well, a years old bug that nobody has discovered until today... :-)
