LCD I2c

[stregato]

I wanted to know if anyone has had experience
with LCD i2c I noticed that exists as a component but there is no explanation.
It can be used with PCF8574?
In the properties LCD address using the PCF8574 with pins 1,2,3 at high level
what value should I set?
Thanks for the help

Hi
Im sure the one i use has that chip, have you a link to the one you are using, all you need to do is add the i2clcd component , the value for the adress should be in the datsheet for the 8574, type the adress in in hex ie 0x27 and it will convert it to the dec equivalent then work , give me a few minute and i'll pop a flowchart up you will just need to change the mcu

Hi
Cant post chart as im using a beta version and it might not open all 3 address pins high should be 0x27 in hex so in the component properties either type 0x27 or 39
Let us know how you get on also can you post a flowchart add some comments as to whats wrong. As it will help to diagnose if it doesnt work
Hope this helps regards
