Wiring issue with BIG KEY button module on Arduino?

Has anyone used those BIG KEY button modules before? I’m trying to hook one up to an Arduino, but I’m not sure if I’m wiring it right since the signal seems stuck low. Do they normally need a pull-up resistor or should it just work out of the box?

Thanks for the replies! I ended up sorting it out — turns out the button module I had was already tied to the BOOT signal, so I just had to adjust the wiring a bit. Working fine now.

Does this have anything to do with ST ?

It doesn't seem so - hence @mƎALLEm's questions!

It sounds like you'd be better asking on the Arduino forums: https://forum.arduino.cc/c/other-hardware/196

Or, if you're using STM32Duino, on their forum: https://www.stm32duino.com/

 

They will want to know what Arduino you're using!
