Re: is it correct the raspberry pi 0 has no spi headers?

Raspberry pi 0 It has no spi headers I don't know any reason to think that statement is true. This documentation for the 40-way header on the RPi board makes no mention of an RPi Zero being different to other models in this respect. https://pinout.xyz/pinout/spi Do you have reliable documentation t...

See - https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=180383 However, running your RPi physically headless does not prevent you using GUI applications.

Re: GPIO control motor through LN293 problem

You have probably used setmode(GPIO.BCM), because the Broadcom GPIO numbering scheme stops at 26.

Maybe you should be using the numbering scheme that refers to the physical pin numbers on the 40-way header?
