I've written in assembly language for 30 years now. I still write in
assembly language for some projects, but most of my embedded programming is
in C these days.

My current project uses a PIC16F877 and I used the Hi-Tech C compiler.
Easiest time I ever had with an embedded system. There isn't the first line
of assembly language in it, and yes it uses interrupts.

This is a commercial product and the first production run of 500 ships to a
single customer in less than 2 weeks. (International no less!)

I like assembly language, but it is not as required as it once was.
Understanding the chip and the subsystems is the tricky part if you really
are a C expert, but then it took about 10 years and 3 million lines of code
for me to become a real C expert. It is not always easy to outwit the
optimizer.
