| serial_printf is a printf for Arduino Serial output that uses no dynamic allocation (malloc) | |
| and constant stack space (in addition to that of printf). | |
| Supports the same syntax of the standard Arduino/AVR printf-like functions. | |
| Returns the number of characters printed. | |
| Examples: |
| // Just an experiment to build a minimal "fix" for | |
| // https://github.com/golang/go/issues/20135 | |
| // using go generics. | |
| // | |
| // It's actually a better "go" map than the builtin | |
| // ones, as the zero value is a valid map. :) | |
| // | |
| // WARNING: ONLY MINIMAL TESTING HAS BEEN PERFORMED. | |

This document lists ISA or processor implementation wishlists/ideas.
They are mostly random ideas; they are not reviewed, guaranteed to work, or even just make sense, but at some point I had good use cases for each one of them.
ISA wishlists found elsewhere.
| # there's a bunch of things that don't work properly: | |
| # - can't capture computer audio output - it desyncs | |
