Perhaps I'll answer with a short list of projects that we have realized so far:
1.The most complicated thing I've done with Ultimate_PIC -I have to familiarize
with that name now- using the 16F628A is a bi-directional half-duplex interface
to connect a Siemens T100 TTY (50baud) to a normal PC RS232 (9600 baud with
hand-shaking). The program manages 2 input-buffers and 2 output buffers,
converts ASCII to 5-bit Baudot code and vice-versa; it surveys the TTY FIGS/LTRS
status. The program is set up as a state-machine. Most of it works as interrupt
handlers. The translation lists are stored as look-up tables in the program
-this is very fast! The interface works well in both directions with a simulated
TTY. The only trouble is that we still have a current problem to drive the TTY
coil. Philo has suggested a solution that we didn't test so far. But from the
PIC point of view, everything works without fail.
2.Another cool project is from 2004. Francis Massen, a friend of mine maintains
Luxembourg's best meteo-station located in the LCD a college -which received a
visit from Chris Rogers in February this year
(http://www.lcd.lu/album/2006_2007/album0607.php?from=15). Francis also observes
ambient radioactivity and he therefore uses a very expensive sensor RS03 from
Bitt Technology. This sensor communicates the data via RS232. But Francis needs
the radio-activity level as a voltage between 0 and 2 V (12-bit resolution). The
challenge for me was to design an interface that would sniff the serial
communication and extract the correct radio-activity level in nSv/h and convert
it into a proportional voltage. This was done with a 16F628 too.
http://meteo.lcd.lu/news/old_news/news_2004.html. You can see the life result at
http://meteo.lcd.lu/today_01.html. The page is updated every half an hour. The
radioactivity comes from the RS03 via PIC interface. (No fail since 2004, one
firmware update.)
3.Our RCX IR/RF radio repeater is another rather complex 16F628 project:
http://www.convict.lu/Jeunes/Mars_Mission_B/Mars_Mission_B_Main.htm
4.My favorite PIC is the 16F88. We have realized a most exciting still
top-secret project with this one, where we unlock all the power of it.
Once you've installed Ultimate_PIC, please go to the LabVIEW or ROBOLAB
vi\addons\PICLab folder and go through the install instructions. (This is not
absolutely necessary, but recommended only.) In the PICLab palette you will find
a HOW-TO menu with a tutorial. Note that we will now replace the name PICLab in
all the files shortly.
