I'm actually trying to do an application to show some info into the display (it's a TRIMODS 1537 , here its datasheet: https://www.farnell.com/datasheets/18286.pdf), but despite I've a code that I think it should be working it doesn't.
I've tested the display and I think it's showing some behaviour that's not normal, so I'd like to make sure that this indicates that the display is malfunctioning or it's a normal behaviour and what is wrong is my code or the way I'm connecting it.
Wether the wire on pins 4, 11, 12, 13 and 14 is connected to a "0" output from the microcontroller, to 5 V, or not connected anywhere (wire on air", I get 5 V, if they are grounded I get 0.
I thought that maybe had to do with the Enable pin, but wether it's 0 or 1 it doesn't change the output of the other pins.
I find hard to believe it can work correctly this way.
Also, could anyone please tell me a basic code that's assured to work for showing something on an LCD display? I'm using PIC18F4620.
Thanks.
