Pinout for 74HC595 using ESP8266 #194

Closed DJPatron closed 1 year ago

Please help. How to connect 74HC595 shift register to ESP8266? I never able to find correct pinout. Floppy is driving to the end by itself and whirring at one place, and never gets back.

If you're using a shift register for floppy drives (i.e. you've uncommented INSTRUMENT_SHIFTED_FLOPPIES in the config file), then aside from the latch pin (defined as pin 2 on this line here), it's using the default SPI pins for the ESP8266. It varies a bit based on the board you have, but you can find some info here (or by Googling your specific board).
