Sorry for my poor English.
I just bought the raspberry PI 3B+ a few days, don't know what the
gpio -g write 1 0 mean.After try this, my pi doesn't work now. the green led is also not lit.
I have an LED light, I want to be able to light it, then I connect a wire to the first pin, which is +3.3V, the other wire is connected to GND, the light is successfully lit, then I Google searched for
gpio -g write to customize the output of the pin, and thought that 1 represents the first +3.3V pin, so I want to test whether it can be used by
gpio -g write 1 0 The output is set to 0, so that LED should be extinguished, but when I execute it, there is no current output on both pins of +3.3V, it completely fails, and PI does not work.It will not start automatically when it is powered on, only the red light is always on and the green light is not lit.
Another small supplement, I am connected to the circuit when the Raspberry Pi is started, and plug and unplug multiple times.
It seems that it really burned completely.
Is there any way to save it? Buying a Raspberry Pi is a big expense for a student.
