LCD is not receiving data from PIC16F877A
Dear informer Engineers
16x2 line LCD display dosen´t work with a programed PIC16F877A after the programed plan have been insert to the chip and connected according to avialable Data sheets to LCDs Note : all programed options are working exellent with my Laptop
not in PCB. I have two models of 16x2 LCD
1- 1602A
2-EB-005--3 lcd Board
the connections are as falowd
------------------------------------------
PIC16F877A :pins To 1602A :pins
B0 D0
B1 D1
B2 RS
B3 E
B4 D4
B5 D5
B6 D6
B7 D7
pins :RW,D3,D2 D1 and D0 are connected to G
The oscilator been used is 20 MHZ for PIC drive

Re: LCD is not receiving data from PIC16F877A
Dear informer
I have the same problem of receiving programmed data from my PIC16F877A to be displayed on 1602A 16x2 as I mentioned be for every thing works ok
with my laptop shows when I transfer Data to my mentioned PIC and connect the interfaces as I see on connection data receiving from display pin connection info
for an expariance I used HD44780 Charater LCD wc11/12c serial Adapter
the result is the same no data displied
looking forward hearing from you
as you can see I am able to open your information pages

Hi
Could you attach your Flowcode project and a circuit diagram to this post?
It would be a good idea to start with something simple, such as just putting "Hello world" onto your display.

Re: LCD is not receiving data from PIC16F877A
hey
I hope that you can see the display data it has been programmed by using Flowcode 6
using Oscillator with several capacity HS,XTAL-RC, Start 20MHZ -16 MHZ -8MHZ- 4MHZ.
RC also regarding to calculation from my Electronics Tables And Formulas book tried with a few capacity of Capacitors & resistors
I know that I don´t know very much about programming PICs But i do have the experience of programming Sony´s play stations 2,3 Hard Disc
for 4 I got vary busy to attend
looking forward hearing from you
with regards
Nasim

Re: LCD is not receiving data from PIC16F877A
Hi Nasim,
You need to add an icon lcd_eb005::Start() as the first icon of your program,
can you try that?
Also, your project target is 16LF1937, is that correct?
