Hello David
Thank you for your feedback. Yes I've tried to change the contrast. No real
effect.
I obtain once some strange characters at the right side of the LCD.
I don't have other LCD, But I've order one Arduino Kit + LCD. Hope to
receive it soon. However, I don't know if this is directly compatible.
Can I use this with any LCD ? Are the pin settings of any LCD 2*16, 2*24
etc... always the same locations ?
The LCD I have is the one provided by Louis. I just plug it in the 1-Wire
LCD board such as indicated in the photo. I check in the manual too.
Thank you
