Electronics People! Can someone walk me through what is going on here?

On the regulator side of the added 100K resistor, I read an expected 3.3V. On the chip side, it is ~3.0V. Is that right?

It is meant to pull-up that GPIO pin replacing the SMT 100K pull-down resistor that was on the board...

@diyelectromusic well, sounds like the pin does not like it to be pulled up. Have you changed the configuration of the pin?

@diyelectromusic So the chip is not programmed by you? maybe it is set internaly to pulldown with an additional external pull-down resistor...so when you change the external Resistor to pull-up you get a voltage divider between the external pull-up and the internal pull-down.🤷

@diyelectromusic I don't what the chip in the middle is...so it's all wild guessing🤷

@diyelectromusic according to this: https://www.vlsi.fi/fileadmin/datasheets/vs1053.pdf you need to change pin33, not pin34.😉

@diyelectromusic let me have a second look

@diyelectromusic do you have a schematic of that board? also the solder blobs on pin 10-12 and 20-22 do not look good...20-22 are GND, so this is fine...could you double check if 33 and 34 pulled-down usually and 34 is not accidentaly connected to GND(somehow, not infinite resistance)...and maybe check if the large pin on the voltage regulator is actually Vout...is this a 4 or 5 stripe coded resistor?

@diyelectromusic 😕 this schematic shows 34 unconnected...

Ich bin kein Jurist aber meine, dass Menschen, die friedlichen Demonstranten grundlos Schmerz androhen und sie quälen, in einem Rechtsstaat nichts in der Polizei zu suchen haben. Werden diese Beamten suspendiert? Müssen sie sich vor Gericht verantworten? Was sagt der Minister?

RT @stephanpalagan
Das ist Körperverletzung im Amt. Mit vorheriger Androhung. Das fällt sehr deutlich unter die EGMR-Definition von Folter.
