I'm still a novice C programer, so I guess I'm uclearon the difference
between a library and a built-in function.  One of the reasons I went with
CCS was its rich set of available functions for A/D, serial I/O, PWM,
interrupt handling, etc.  There are also a lot of example programs and
quite a few of what I would call "libraries" -- that is, a set of
functions that can be #included in your program.

Some are less useful than others, yes -- like the LCD and keypad routines,
which you would of course have to modify for your hardware.  A lot of
others, though, are highly useful.  For example, the compiler will
determine by the pin assignments in a pragma statement whether serial I/O
is being done with the hardware UART or bit-banged, and use appropriate
code on its own - though you can even specify to use bit-banged serial
using the hardware UART pins, for example if you want to send 8 bits plus
parity.  The ADC routines are simple but save an awful lot of time, and
generate code almost exactly the same as what I'd do in assembler.

So I don't know, does HT has that sort of thing built in?  At their prices
it wasn't a viable choice for me.  Personally, though, I *really really
like* having such things as putc(), getc(), pwm(), read_adc() and that
sort of thing available without having to write them from scratch and
#include them in every program I write.
