Hi everyone,
I recently got an LCD screen HD44780 that I made worked with my Mbed. But lately, the screen does not work at all (nothing happens) whereas the program hasn't changed. It is possible that some electrical connections have been interrupted, but now everything is as when it worked well.
Currently, I try to do a reset of the HD44780 because I guess he has put himself in a state other than the one expected by the Mbed. No reset button is present, so I guess it must be reset manually by software ...
Do you have a solution? Why the screen goes blank? Should I do a reset and how?
Thanks, I am really looking forward to your reply.
