Stap 4: Montage-code voor 8051 microcontroller
Compileer deze asm-bestand met elk 8051 assembler-programma. Ik heb dit ASEM-51 -assebler gebruikt. Het creëert een hexadecimaal bestand, die we nodig hebben om te uploaden naar de microcontroller met 8051 programmeur. Ik heb gebruikt "Top win universele Programmer". Controleer het hier boven winnen producten. Het kan worden geïnterfacet met zoveel microcontrollers, eeproms enz.
