Re: Ускоряем работу Arduino
Всем привет, и огромное спасибо за библиотеку, как автору, так и тем кто тут принимал активное участие в тестировании и доработках.
Делал себе очень похожий вариант для Меги 2560. Только ещё вспоминаю С/С++ после 17-и летнего перерыва, так что "сильно не пинайте". Полностью всё, ещё не проверял, но может что-то сгодится для Cyberlib:
заголовки. Файл Arduino.h:
PHP код:
/**
* For smaller program to Arduino IDE
*
* @author Arhat109 at june 2015. [email protected]
*/
#ifdef _ARHAT_
# include "arhat.h"
#else
# include "Arduino_orig.h"
#endif
Оригинал переименован для того, чтобы втыкая в скетч строку
переключать компиляцию скетча с типового файла на этот:
PHP код:

Ну и моя реализация wiring.c (таймер времени и функции задержек). Поскольку пока ещё не силен, часть выдрал из типового wiring.c (отмечены).
PHP код:

*
* use timer0 as default and prescaler 1/64 for each 4 microseconds with 16Mhz CLK.

*
* For use other timer you need predefine all constants in block TIME_DEFAULT

Основной недостаток, который вижу - это пересчет из тиков таймера по 1024мксек на 1000 при чтении времени. Там, насколько смотрел результат сборки подключается целочисленное деление из стандартной библиотеки. Наверное это "долго".
В общем, "на суд сообщества", ну и может будет что-то полезно. Наименования функций "придумывал сам", ещё до знакомства с Cyberlib. На этом ещё мало чего написано, можно поменять названия функций на более популярные грепом.
Идея была в том, чтобы постараться адресовать порты и биты по номеру пина платы Arduino Mega 2560. Прописаны все пины, в т.ч. сделаны заготовки под неподключенные.
