Arduino Library for 74HC595 8-bit Shift Register
Library for hardware SN74HC595N SN74HC595 74HC595N 74HC595 DIP-16 Shift Register 8-Bit
Installation guide for Arduino IDE
//Pin 11 ST_CP of 74HC595
#define latchPin D0
//Pin 12 SH_CP of 74HC595
#define clockPin D1
//Pin 14 DS of 74HC595
#define dataPin D2
//How many chip are cascade connected
#define numberOfChips 2
constructor ShiftRegister595(numberOfChips, latchPin, clockPin, dataPin);
and begin() in setup function.- begin() - call once in setup function for config pins
- void write(uint8_t out, uint8_t index) - set specyfic byte of register chain
- void write(uint8_t out) - you can use for 1 chip
- void write(uint16_t out) - you can use for 2 chips
- void write(uint32_t out) - - you can use for 4 chips
/*
* This is an example of two cascaded chips.
* uC pins 'latchPin' and 'clockPin' have to connect with all chips (pin-11 and pin-12).
* 'dataPin' (pin-14) connect only to first chip.
* Next chip pin-14 connect to Q7' (pin-9) of previous chip.
