the product works as expected, use the following arduino library:
https://bitbucket.org/fmalpartida/new-liquidcrystal/wiki/Home
with the settings:
#include
#include
#include
#define I2C_ADDR 0x27 // <<----- Add your address here. Find it from I2C Scanner
#define BACKLIGHT_PIN 3
#define En_pin 2
#define Rw_pin 1
#define Rs_pin 0
#define D4_pin 4
#define D5_pin 5
#define D6_pin 6
#define D7_pin 7
LiquidCrystal_I2C lcd(I2C_ADDR,En_pin,Rw_pin,Rs_pin,D4_pin,D5_pin,D6_pin,D7_pin);
5 stars for a product which works as expected
Well packaged, received in good condition and excellent delivery time (
11 calendar days from order).
I generally use this as a general "Port expander" rather than as an LCD back pack. The PCF88574 is super useful and I highly recommend it.
Tips:For questions about your order, place of delivery, product discount, taxation, delivery time, warranty, shipping, payment, exchange rate, and other questions unrelated to the product, please contact customer service.
