PWM with AtTiny85

tanik1:
excuse my stupidity.

the link provided Simple SD Audio Player with an 8-pin IC

what software do you need to view the source codes?

and can this be done with the arduino?

or is there someway the arduino can view this code?

If you're comfortable with AVR code and Arduino then you can embed the asm into the c.

I have done zero AVR assembler. I am fascinated at the idea of having 32 CPU registers to work with but so far the compiler is tight, faster to write, and does the right thing if I'm careful plus I already know C/C++ well enough for my Arduino needs.

There was an audio project with a wavetable or two earlier this year.
