Was noch gemacht werden muss, bis der Tastatur-Treiber funktionieren könnte:
2015-10-10 22:45:02 +00:00
☑ Support für beliebige Typen in Copper
☑ Pushen von Typen != INT
☑ erweiterung von pushi um typcode (u?int(8|16|32), bool)
☑ erweiterung von pushr um typcode
☑ Simple type checks in Copper
☑ Custom types in Copper
☑ Native function calls in Copper
☑ Bitwise Operations
☑ outb und inb
☐ eventuell hex literals für Copper
