    RPI zero w - 3.5” waveshare touchscreen

    Hi,

    I recently try to install a 3.5” waveshare todichscreen following this instruction for RPI 3B, everything works well until the point of the calibration, the cross appear in a corner, but the touch does not work in any place of the screen.
    I going to try again from zero in a couple of days…..but Am I missing something important about been working with pi zero instead a 3B?

    Thanks in advance!

    There is nothing in that procedure specific to the pi3B.

    Today I did everything again and the touch does not work. Tested the same scree in RPI 3 and works ok.

    Could be that RPI zero or the soldered Gpio?

    How can I test de gpio pins?

    Thanks!
