Steve,

Sounds like a good combo for playing, 2313 and codevision. Any particular
are where you are have the most trouble or is it a combo of C and hardware
understanding !

Subject: [simmstick] Simple .c file to figure out how to flash LED's


Hello All,

I'm trying to learn C and I'm having a hell of a time. I'm doing this
on my own with NO help. I have programmed a little with Bascom and
seem to have an easier time of it, but I have yet to make an LED do
anything using C. I seem to learn best from an example. If anyone
would be kind enough to provide a templet.c that is compatable with a
DT006 and the serial UART, I think I could learn from it.

I understand the basic concepts... The chip is just too stupid to
understand what I'm saying. :) I can't even get the CVAR wizard to
printf "a simple text".

I'm using:

AT90S2313 @ 10M
Codevision Eval or WinAVR

Thanks for any help,
Steve

Ingmar,

No particulars. I have found that since I can't make a working copy 
or modify one of the other chip/proto board examples to function on 
my setup, I'm asking for a file that will compile or both a compiled 
and source copy that will allow me to make changes and either proceed 
or backup and try again. I have learned to mostly use the ("print"-
basic) or I believe the ("printf"- C) command to produce results that 
teach me what is going on. I hope you can remember or at least 
empathize with my procedure.

... I guess C and hardware understanding. Producing a base platform 
in order to learn on. One small step at a time.

Thanks for the reply,
Steve

Hi,

I am thinking about emulating an OSD with a PIC.

I would do it on a PIC16F628 at 20MHz.

Did anybody already write such a program?
Do you have any reasons to think that my project is going to fail?

Many thanks,
Thomas.

G'day everyone

      If were to use the two PWM module on a PIC16f877 on a DT106, I 
dont need to solder XTAL2 and the caps right?
    Do crystals found on watch clocks work on PICs? I believe they are 
running at 32khz?

I've finally grown tired of just blinking LEDs with my PIC micro. 
Next step, write to an LCD:-)

I'm trying to use the serial LCD product SLI-OEM made by wirz
electronics.  So far, I haven't been able to get my bit-banging code 
to actually display anything yet, but before I go off the deep end, 
I'd like to confirm that the SLI module is even working.

When I attach a 16x2 LCD and turn-up the contrast, the top row 
displays the entire 5x7 matrix for each character, bottom row 
nothing.  If I attach a 16x1 LCD, and do the same contrast 
adjustments, only the first 8 characters of 5x7 matrix show-up.  Keep 
in mind, no actual characters are displayed, just a solid 5x7 block.  

The module has switch settings for the number of rows and columns of 
the LCD, but none of the settings have any effect on what I see at 
power-up.  I'm not sure what the module does at power-up, but
it seems like it's only initializing "half" of the LCD controller 
(Hitachi).  This makes me think that I either have a bad SLI-OEM, or 
that I haven't connected the LCD properly.

What should I expect to see displayed when I just apply power to the 
SLI module?  For those of you familiar with the SLI-OEM module, I 
have verified 5v on pin2 and gnd on pin4 of J1.  Also verified power 
to LCD connector.  If it makes any difference, this is the older 
version (1999) that was part the original "Extended PIC starter 
package" from Wirz. (OK.  So I'm a little slow at this)

Any ideas?  Anything I should look at to see if the module made 
through the years of storage?

Thanks, Thomas.  That might apply if my PIC was actually the mcu 
driving the LCD, but it isn't.  With the SLI-OEM module, it has it's 
own on-board 12C508 which is controlling the LCD.  As an entire 
peripheral, my PIC is supposed to treat the SLI-OEM as a simple 
serial-driven device.

Although based on your comments it sound like the 12C508 never quite 
initializes the LCD.  I may need to make a mod to the SLI.  I hope it 
doesn't come to that, unless there is a known issue with this version 
of the SLI board.  It is a few years old:-(

Thanks, Rob.  I realize there are some timing issues, including the 
serial input, that I may still have to work out between my PIC and 
the SLI.  Of course, I thought I had that all worked out, but...

So, in an attempt to isolate the problem, I was starting with just 
powering-up the SLI alone.  I was trying to see if I could get some 
kind of defined behavior before even looking at the serial 
interface.  So far, the replies seem to indicate that the on-board 
PIC never actually goes through the initalization sequence to the LCD.

As far as powerup sequence to the SLI, I've tried applying 5v to pin6 
(SerialIn) before Vcc (pin2) to allow the SLI to detect the polarity 
of the input.  I've tried the reverse.  But, so far, all I get is the 
solid block characters.  I was expecting to have some sequence that 
would result with a blank display and some kind of cursor.

Thanks for sticking with me Rob.

I think the "solid block characters" that I described, are indeed 
simply the background of what should be blank characters.  I'm 
obviously overdriving them by fiddling with the contrast pot on the 
SLI.  The only reason I noted that behavior was to substantiate my 
theory that the Hitachi chip on the LCD never really gets initialized 
at all.  Since the row/column settings (on the SLI) seem to have no 
effect on either a 16x1 or 16x2 LCD, it acts like the LCD is simply 
powered with no initialization.

As far as I can tell, once the SLI is powered-up and ready, I should 
be able to start sending serial data to be displayed.  I don't think 
I need to send any special codes.  I should be able to just hook it 
up to a PC and try it.

Thanks for the suggestion.

Hi Jim,

         Sorry I didn't get back to you latter, I don't keep up on the 
SimmStick list these days.  Solid black blocks is a sign of an unintialized 
LCD, its what you will get if you power up the LCD alone without the 
SLI.  You should get an underscore ("_") if the LCD is connected and 
powered correctly to the SLI.  You will get this even without a serial 
source or if you have it the dip switch set incorrectly. Assuming that you 
don't have the contrast turned all the way up as has been suggested then 
you should get the underscrore.  If you don't get the underscore then most 
likely have a soldering problem with the 1x14 connector.  Inspect and 
reflow your solder joints and your problem may go away.  Take a look and 
let me know.

-Ben

Solder?  What's that for? ;-)

In my haste, instead of soldering a header socket onto the SLI, I 
soldered the pin header posts directly to the board.  I knew that 
once I soldered the LCD to the posts, I'd never get it off again - so 
I didn't.  The through hole plating on the LCD *seemed* like it was 
making good contact with the PINs and I wanted to verify the 
placement before I committed myself to solder.

But from the responses, especially yours Ben, point blank said that 
the LCD was not initializing as it should.  Soldered it up this 
morning and now I'm ready for action!

Thanks, everyone.  Sorry to cause so much noise over a silly 
soldering issue.  Geez, the pain we go through for lack of a stupid 
50 cent part >:(

what I want to program

what it reads back after programming.

I`m using an hitachi hd44780 lcd based in an pic18f452 application. 
I have a problem with the standard routine "OpenXLCD()" in C18 
compiler, this routine no pass in sistem, we can help?

Yeah but i cannot afford that, i am a student and need this for a major HSC project...

any other ideas? i have tried with all jumpers off and with 2 different chips.

I have done the tests in bascom and the lines on that parallel cable work fine.

thanks

G'day Dean

This is where patience is required.  The Atmel 2313 chips with a crystal or RC 
oscillator usually identify just fine.  The Atmel chips have internal 
oscillators as well.  When one uses the internal oscillator for a first time (eg 
on the 8 pin chips) you have to provide an oscillating signal to get the chip to 
identify and to set the RC enable fusebit.

So for testing the board use the 2313 chip with an external oscillator as a 
starting point.  If you have a logic probe, can you see the external oscillator 
working?

Cheers

Hey Nathan,
                     I have a resonator on it, a 4 MHz one, yet it still
does not work and I do not have a logic probe to test it with, I just went
out and bought a 4MHz crystal to try it and i will post my results here.
thanks

make sure you put 2 caps either side of the crystal to make it work,
about 22pf should do.
Just solder them to the resonator socket base, so that you can easily
remove them if you wish to go back to the resonator.

Hey don,
             I put the XTAL into the resonator socket with the pins in the
outer two holes and 33pf caps on them. Still not working, should the 33pf
caps have any effect?
thanks
