newbie questions - do LCD have same supply as PIC?

newbie's confusion

https://www.mikroe.com/en/books/picbook/7_09chapter.htm

Hi,
I have 4 questions.


1) In the diagram, do the pic and the lcd share the same 5v dc supply?

2) Also at the end of the lcd.asm main programme,

loop ( Can I add more text in it ?)


goto loop


3) all the text in line 1 and 2 will show up one by one then repeat right?

4) Do I only need to include " lcd.inc and mikroe184.inc?


Thanks

Hi,

Regarding the 5v, the lcd pin3 shares the same rail as the pic chip.

However the +5v to the lcd backlight at the right hand side is not what I would do.
If its a standard black on green display you do not actually need the b/l, but if you do want it on, around 4v is more suitable so use a dropper resistor - try 100ohms but you might need two use 2x 220ohm in parallel to increase the wattage of the resistor.
Depending on the backlight it could take 50 -100ma,

Yes, you can add you own code at the loop stage.

Not sure about q 3/4 as that page takes a fair bit of following - I don't like complicated things - have just sent someone some starter lcd code - have pm'ed you a copy - its for the 16f628A but am just doing the same for the 16F690 for someone else - let me know if your need it changing for a particular chip if its seems easier to use to you than that mikroe stuff.

Hi,

Thank you so much for your codes.

I will study them.

Too bad! I actually only have two 16f690 pics in hand

i am not good at this so i have to study harder

If you could send me the codes for my pic

it would be perfect.

Thanks a lot once again.

Hi,

Will pm you the 690 code.
