I have this library,
I didn't see any helpful information there.
There is a binary file, maybe it includes something, but how do I open it ?

Gil.

Can you share your code ?

Do you think they have a library for picbasic ?

Hi All,
I bought this Arduino I2C LCD.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150618547319&ssPageName=STRK:MEWNX:IT

Can't find any examples or basic code to operate it.
Anyone can...

1M resistor in parallel to the crystal has solved the problem.
Thank all.
Menta.

At first I used capacitors on each device just like the book.
Crystal to PIC with 2x 22pF cap.
Did everything nice smooth and easy. All looked very good.
The whole problem was due to that 2 wires...

btw, I've reached a point where my WW board is working, only when I use LONG wires to the external crystal.
I guess this cause some kind of induction which makes it do work.
I was using a very...

I think i'm not going to use the 877A.
Too much trouble comparing to the 887.
I spent 2 days on this issue and I still can't understand why it works or not.
Thanks.

Its amazing,
When I use the test board (http://dj-gil.com/PIC/posts/math.jpg) everything is ok.
When I put in the wireWrap board (http://dj-gil.com/PIC/posts/WW1.jpg)...

I'm not using all programmer legs, just + and -

How do you explain that when using the power from the programmer, everything is OK ?

And ofcourse, if using the programmer power , everything is ok (with MCLR stright to the +5v)

Well, I really dont know what do more.
On the test board everything was ok. The LED was blinking, the LCD shows the numbers.
Now I wrap it again and it aint work, unless I touch the 8Mhz crystal...

On the temporary board the led was blinking very fast (suppose to have 1 sec pause)
Only when I set MCLR to +5v it started to run ok.

I build a temporary new board and it works ok.
Maybe something is wrong with the other board.
I might build it fro scratch again.
Thanks.

Guys,
Everything is working perfect when I use the programmer power.
A ~700 lines code.
The problem is very simple when connecting outside power source.

From my first post


I'm not using anything beside the PIC and the LCD.

I tried to connect the MCLR stright to the +5V. Didnt help. Will try with RCR.
887 use internal OSC while the 877A use an external.
The code works perfect on both devices when using the USB...

languar I didn't get you point.


DEFINE OSC 8
a var byte
a=0
TRISB=$0
test:
SEROUT PORTB.0,4,[254,128,#a]
a=a+1

Guys,
I have a another circuit with 1 7805 that push the PIC16f887 and the same LCD type.
I think its something else.

i'm using a code to print 1,2,3... to the LCD
I see that it prints the numbers but also print junk,
So I guess something is making noise on the LCD input.
Tried with a resistor to the ground and...

I will.
If I use the second circuit 7805 output and connect it to the first circuit (with the 16f887) it is working ok. (it has same parts including the LCD)

The program is working when I use the programmer as power supply.
I of course compiled the program differently for each controller.
I have multimeter, What is the best way to check the current ?...

Yes, its 16f877A, my mistake.
I tried connecting the MCLR pin to the +5v but it didn't help.
It also didn't help using 2x 7805.
Its very strange because I have another circuit just exact to this...

transformer output without load is ~16V.
7805 output is 4.95 while its on.

I have another circuit usining the same parts, with one change, I use the PIC Kit2 demo board with 16f887 which works...
