'Second Attempt'

Ok Gentle Folks,

Seeing that I never received any responses to my last post, please allow me
to ask the question in another way.

As a newbie, I am quite ignorant of the commercially useful/practical
applications that PIC microprocessors can be used in.  Could anyone say what
are the different uses that a PIC16x84 can be applied to?  I would like to
find a project that will allow me to become more familiar with PIC chips.

Thanks Very Much and Regards,
Ricardo

I guess I'm not sure how much greater a challenge you are looking for.  Your
earlier post said you wrote a controller for a neon sign ... I'm not certain
what that would entail.

One fun project may be to make a digital thermometer that uses one of the
Dallas serial I/O temperature sensors (DS1620 is a good one ... see
http://www.dalsemi.com/DocControl/PDFs/1620.pdf).  You could display the
temperature on a 7-segment LED.  The PIC16x84 dosn't have many I/O pins so
you would need to multiplex or latch the outputs to drive more than one
digit.

For the least challenge, borrow the code for talking to the DS1620 and write
the code to drive the LEDs.  For more of a challenge try writing the code to
talk to the DS1620.  For even more challenge, try a 1-wire serial I/O device
like the DS1820 (http://www.dalsemi.com/DocControl/PDFs/1820.pdf).

You could expand the project by storing min/max temperatures, logging
temperature readings to the internal EEPROM or a larger external serial I/O
EEPROM, making the temperature data available for download to a computer by
attaching an RS232 interface, etc.

Just a thought.

Ken

Do you want a commercially useful project, or a "learning project"?

PICs are widely used in things like mice.  As a geneal rule, they get lots
of use connecting arbitrary I/O devices to "standard" communications
channels.  (The mouse is an example of an X/Y position/motion sensor to
rs232 converter, more or less.  Rs232 LCDs, thermometers, motor drivers,
clocks, timers, relay drivers, radio control "things" and others seem to be
pretty common.)  They ARE general purpose microcontrollers, and could be
used anywhere that the necessary code will fit (thermostats, microwave
ovens, telephones, door locks, toys, etc, etc.)  The sky's the limit - the
choice of a particular microcontroller rarely makes or breaks a product
idea - limitations probably show up ... elsewhere.

The cannonical "learning project", OTOH, tends to be some sort of LED
flasher.

I too am a newbie at this.  I took the "standard" advice and programmed a 16F84
to blink an LED, as a starting point and to get familiar with the  process.  I
was able to get the original source file to properly assemble, and after some
programming errors, finally able to get the program into the 15F84.  That is a
recommended "learning" process to get started......

Ok, I too am a newbie, and to that I know of
electronics and hardware. But I am a keen PC
programmer, and decided to try some other platforms
too. So I will tell you what programming I have done
on a PIC, just for the idea. These are of course
comersial applications, but who says you cant do them
too :)
I did a fridge controller for 16c505, for a frdige
system with a compressor, a heater, two termostats and
such.
I also did a phone dialer, that can be programmed by
an external keypad (a friend of mine made the
hardware).
You can do any such device (or something simplier) for
exercise. Do the damn led flashing routine, make a
decimal calculator, make dec to hex convertor.
Just don't give up, that's my advice. Don't stop at
errors and do not be afraid to ask.
