<DIV><FONT size=2>HELP, I am new to the electronics arena (I'm a registered
Civil Engineer) and have recently completed a chronograph project where the
results are displayed as time (milliseconds) The system was built using TTL
logic and works just fine however I want to convert the displayed data into a
velocity( ft/sec or M/sec).&nbsp; I can generate data with existing components
such that all I have left to do is take the inverse (1/xxx) of the data and
display it.&nbsp; I want to pursue using an MCU and all I read tells me the PIC
products are the way to go but I am confused with all the available hardware and
software available.&nbsp; Question is what do I really need to buy?? most of
what I do is strictly R&amp;D/one of a kind stuff.&nbsp; I do have some
programming experience in fortran, cobal, basic etc and I do do industrial

greatly appreciated and I promise no more Books to the list.</FONT></DIV>

Yes, this can be done with a PIC.  You can start with a PIC16F84 which
is EEPROM.

NONE at all.  The development software MPLAB is free. You can download
it at the Microchip website (http://www.microchip.com).  It includes a
simulator and an assembler.  You must learn the assembly language (only
30+ instructions).

For the programmer, you can DIY it (do it yourself). Check
http://www.gbar.dtu.dk/~c888600/newpic3.htm for the diagram and the
software.  This is a serial port programmer and requires no external
power to operate (power is taken from RS232).

regards,
Reggie
