ще дадем и пълният програмен код от примера. в предния урок има линк от където можете да си го изтеглите, но все пак ще дадем кофа и като текст тука за по прегледно съдържание. готовият компилиран *.hex файл можете да си изтеглите от рар архива от този линк http://karadev.net/basto/adc_leson/adc_leson.rar
отново ще покажем схемата според която е написан софтуера и неговата функционалност
