Hi, have you solved this problem yet?
COuld You please explain what You mean?
The post is a week old, perhaps he has already found a solution.
The problem is still there.
But in the mean time I found out that the affected board takes significantly more current than another board that does not show this effect although it should be identical.
Still investigating. I will post when I found the solution.
long time ago...,
but the problem is still there.
On the board I wrote about last year, there was one IC misplaced that lead to the higher current.
But even after fixing that, the measurement was still temperature dependent.
In the mean time, I have tested about 30 boards, 3 of them show the phenomenon that the reading drops when the board reaches about 40 degrees centigrade.
I have also tested "normal" boards. They show a drop of the readings when the board temperature goes up to more than approx 75 degrees centigrade, which I think is acceptable.
