STM CircleOS forum / A problem with the Button

Silver_Surfer · 2008-05-22 15:46:19

My STM32primer does not work correctly. I got it yesterday. I'am so dispaired.
It runs through the menues, Button uncontrollable.

The message "Shuting down release Button" appears.

It seems the Button is electrosensitive. Maybe the pullup resistor is gone?
I expect a pullup-resistor to be there. A schematic would help me. Can someone post the direct link to a schematic?

The schematic is on the 'resource' section of this web site:

The button is a very simple 'mechanical button' and it seems that the issue is probably mechanic (or in the soldering?).
