K8038 dimmer question

Kits Home Projects
1

I cannot find the following information in the manual for the K8038 dimmer module kit, so I wonder if anyone can help please.

I wish to know the longest duration of the push button being pressed which would still be ‘seen’ as a SHORT push? At what stage does it become a ‘long’ press?

For example, I am wondering whether it is something like this:

0 – 50ms IGNORE

50ms – 250ms SHORT PRESS

250ms – upwards LONG PRESS

What are the actual design figures please?

Edit: 10th April 2008

OK, no one seems to be able to help me here, so who knows how I can get the information from Velleman, in other words the person who designed the circuit / wrote the firmware for the PIC chip in this dimmer?

When I asked Velleman, they told me to come here to the forum.

Anybody help please?

hi there,
honestly, the best way to find this out is to experiment…
be careful though as it carries mains electricity
a long press is usually about 1 second>

I hope I have helped you!

Hi,

yes, I could do that, but as the pulse duration acceptance windows must be set in firmware, I would have thought Velleman could have published the design values. Would be easier if they did.

Anyway, thanks for the reply.

yes, I agree, it would help, though I would go for 0.1 seconds
hopefully this message will get throught to Velleman…
best of luck,

Hello,

The delay (debounce) times are as follows

0 – 80ms IGNORE

80ms – 600ms SHORT PRESS

600ms – upwards LONG PRESS

These times are @ 50Hz netfrequency., @ 60Hz these times are a little shorter.
