the like. The advantage of the C language portability is lost
when these different various hardware configurations
depend on a unique set of configuration and operating
parameters. C just makes this job harder.
3. I just enjoy programming and knowing what is
going on in the logic of the microcontroller. There is
nothing between me and the hardware. There’s something
satisfying in knowing exactly what the hardware is up to
and manipulating the program at its most ‘intimate’ level.
In addition to controlling my TV’s volume, I control
the audio from my older Yamaha receiver that’s plugged
into a multi disc CD changer. I can now adjust the audio
as I like from across the room. I just grabbed an old
remote from a defunct TV to use as the IR controller.
Now, if I can just remember where I left that remote.
