I have a small problem: I want to use pin 13 [GPIO 27]. (pin 13 [GPIO 27] should output 3.3V)
I tried [in Shell (Putty)]:
gpio mode 13 out gpio write 13 1
but nothing happened.
I also tried pin 40 and other pins, but it doesn't work. But with pin 7 it works.
Is my pi broken? Or what is the problem.
