Hi Jason:
I've done a number of PIC projects in assembly language because it like it.
I like the 8 pin parts where they are all that's needed. But if you want to have USB or LAN connections then you'll
need one of the much bigger parts or better already assembled boards.
With a simpler part there's less to learn. Here's an example of a circuit that
has 12 LEDs all driven from 4 PIC pins.

This is an LCD clock and it uses the PIC 16F88 and is interrupt based, where assembly coding is mandatory because every
machine cycle is critical in how the interrupts are handled. This is a "time nuts" clock where the external frequency
reference is the heartbeat of the micro controller. The time can be set to a millisecond (the 1 PPS output is as good
as the reference oscillator) and the date functions go back to fifteen hundred something as well as day of the week.

Have Fun,

I've decided I finally want to tackle learning how to use a PIC chip for some
smaller projects. Can someone recommend me a good (and
cheap) PIC, and possible some literature (be it a book or website)? I have a
fairly recent willem eprom programmer that I'm hoping I
can use.
I don't know what all the features PICs have, but for my first project I would
like to have it connected to a serial port on one of
my Soekris' where it can grab info (i.e. the current time, or NTP/GPS info) and
output that on a little LED display.
