Hi, I've got some questions about this library.
Why I have to specific R/W pin in the costructor? In the library there isn't any functions to read from the LCD. I put the R/W LCD pin at the GND so I can use less pins from Arduino. How can I do? Is it possible to not specific that pin in the costructor?
I don't know LCD very much, I've just started to study it now. I've read from the datasheet that I need to initialize the LCD controller with some command whit some delay (about ms). In the library I don't see delay and the init command repeated 3 times. Why? Isn't this less compatible?
Thank you in advance for your help. Albano
