Hello everybody,can anybody tell me please how the conversion is done when interfacing DOT Matrix to microcontrollers (PIC16F876A for example)?
Reffering to https://http://embedded-lab.com/blog/?p=2478;I do not see how those values which give letter "A" are found.

Can somebody help please?

Thanks
 

0x7e, 0×09, 0×09, 0×09, 0x7e = letter A ... but picture of A /on display / shows another code / 0x7e,0x11,0x11,0x11,0x7e/

Hello there,are those conversion standards or there is some techniques used for converting;we consider the first one {0x7e,0x09,0x09,0x09,0x7e} or the second which is given by the picture {0x7e,0x01,0x01,0x01,0x7e}.

How may I proceed for example to display the world "Hello"

Thanks.
