Вопросы:
- почему компилятор вставляет функции (TransmitByte) на место их вызова
- как сделать штоб функции нормально вызывались
P.S. Сори если вопрос дурацкий
Компилятор считает, что "накладные расходы" по сохранению/восстановлению контекста при вызове функции выше, чем просто проинлайнить такую функцию с инкрементом аргумента во внешнем цикле.
