Dave, with your last example code nothing help. I insert pause 250 between instructions and appear something like this : "ell o Hello " on LCD, but a very low contrast.i have not enough free time to change resistors from 1k to 4k7 . So, Its a good way! Thx Dave and Robert!

Very strange, I tried quickly some variants to display a text without succes. I wrote again working code and again nothing on LCD
So,now I must go with my family to party and "next year" I'm back to try.

Again 1000x thx and Happy New Year to all forum members !
