Hello
I’m getting strange results from the dS3484 analog ports.
The values displaying on the index page are unstable.
Even with a pot connected directly, the values are jumping up & down.
Other ports on the board are doing the same thing.
Any ideas anyone?
Thanks
Hello @martyk
Was the board behaving different in the past?
Can you share some screenshots of the displayed values?
Do you own more of these boards?
Thank you.
Hi
As a test setup, I have a pot set to 2.00v connected with short leads,
I tried a 330µfd/10v capacitor on the port: makes no difference at all.
The binary output on the webpage is jumping from 617 to 620.
I know this doesn’t seem like much, but I am doing temperature measurement and cannot live with this instability.
Here is a screen-shot:
AC mode
5µs/div
I have 2 of these boards. They are both performing the same.
Thanks
Hi @martyk
Thank you for your reply.
How are you powering the boards?
Did you already try to contact Devantech support?
Hi
Devantech says this is normal ADC behavior.
They say to write an averaging filter into the code.
Now all I have to do is find some examples to copy : - (
Thanks

Good. Thank you for this information
