Button1 (start/back) not working
#1
I have a problem with start/back button. It does not do anything... I have soldered two MiniEngine2 shields and both have exactly the same problem.

I had to order shields from seeed.com with Gerber files because these shields are not available at webshop...

Could that custom shield cause the problem? If it is soldering problem then it is quite strange that both shields have that same problem.

I tried to use voltage meter to find problem but I don't know much about electric stuff so maybe someone can tell me that are those values correct. You can find video link below where measurement can be seen...

Here are the values in written format ( I took measurement from SN74HC14N )
9 input 8 output
11 input 10 output

SETTINGS BUTTON (btn_2) -> this one works fine
1) button up  - metering from input pin 11 => 3.26
2) button down - metering from input pin 11 => 0
3) button up - metering from output pin 10 => 0.6
4) button down - metering from output pin 10 => 2.38

START/BACK BUTTON (btn_1) -> this one does not work
1) button up  - metering from input pin 9 => 3.26
2) button down - metering from input pin 9 => 0
3) button up - metering from output pin 8 => 1.43
4) button down - metering from output pin 8 => 1.53

I have put Serial.println command in code and nothing is printed when btn_1 is pressed. When I plug power on then the btn_1 is triggered once...

Doen anyone have any clue how to fix this problem?
