Hi,

I'm using MicroMod Mix3 to capture state of digital inputs. I use DIN0 - DIN2 as inputs and while set on all of then reference 4.8V when capture received data by using candump I see n that I get logical 1 but after some seconds it goes to logical 0 and then back to logical 1. as said I have stable input voltage 4.8V. Any ideas what can cause this issue? I have basic setup only (no changes in DIP switches though). Thanks.

Hello,

Can you send us your configuration-file (.mcf) to support[at]peak-system.com?

Please reference this post in your email.

It's hard to evaluate whats the issue without seeing the configuration.

Best Regards

Hi,

it looks like I need to provide input voltage higher then 4,7-4,8V otherwise detection is not reliable. Not I provide bit more and it works perfectly fine. Thanks.

4.8V is the minimum Voltage for detecting the High Level. it is always better to add some milivolts on top for exact detecting the High Level.
