the 16x2 lcd runs properly on the code...
the line 2 and 4 does not display anything...
ok thanks I will try it...

I'm still having the same problem... black squares on line 1 and 3... no display on line 2 and...
my lcd won't display properly... what could be the reason when I am having black squares in line 1 and 3??
I have tried changing my microcontroller but I still get the same problem... I already check the wiring and soldering...
hmmmm... I am using pic16f877a... could you share a link where I can get a code that I could compile? I have seen many tutorials but I cannot understand what to do and how I will write the code...
so in this 2x16 initialization **broken link removed** I do not need to modify anything? because on the part on the LCD initialization, it says on the comment that "Function Set to 8 bits, 2 lines and 5x7 dot matrix"...
:) If you have an initialization code could you please share it to me...
Please help me...
Could anyone share a URL/Schematic/Code that will initialize a 4x20 LCD using PIC16f877a
here's the datasheet for the LCD http://www.e-gizmo.com/PRODUCT/ELECTRO/Datasheet/Display/sc204a.pdf
I have a 2x16 lcd and I have already initialize it using this code **broken link...
This is the connection written on the back of our coin slot... It is a single coin validator.... I am planning to buy another coin slot, so I could use 2 kinds of coins... But if our budget can purchase a multicoin slot, I will replace this coin slot...
Gray: Counter +/-
Red: DC +12v
White...
Displaying and Keypress is now ok :D
^^ Thanks for all the help...
My next problem is how to connect and code a coin slot and gsm module on pic16f877a
Please help me...
oh it's finally working ^__^ I tried to change the connection from the schematic on the pdf to the sample schematic on the Mikro C lcd library... :D
I am now trying to connect keypad on my circuit... I will ask again later for help if I will be having problems... thanks to all :D
I think I have connected it correctly 'coz I already tried redoing the circuit many times.
:( I wish I could make this work.. especially using the keypad...
I have followed the schematic and used the code on the pdf file, but all I got is this
sometimes it displays random letters/characters.... like it will display a continues F that will fill the whole screen...
what could be the problem??
When I used **broken link removed** the one with LCD...
wow thanks for all the help.
I am still having problem in displaying some text on the lcd but I am still trying some those tutorials that was shared in here ^^ thanks... I wish I could make this work... I don't have much time left to finish my thesis... and I am still trying to learn about...
Could anyone post a link or an example of circuit for pic16f877 interface with a 16x2 lcd with 16pin? please I really need help...
If possible please post a C code for it...
And it will be much better if it is also interfaced with a 4x3 keypad....
I'm sorry... I am a newbie in...
