Я изучаю (и пытаюсь научить) электронику/программирование с некоторыми друзьями. Мы решили построить светодиодный куб, используя пусковую панель для нашей задачи.
Здесь проблема, с которой мы сталкиваемся:
Для наших анимаций мы храним их в двухмерном массиве. Мы получаем ошибку, если мы определяем массив как константу
Я не хочу, чтобы этот массив находился в ОЗУ, потому что у нас нет очень доступного.
EDIT: см. ниже код
Я надеюсь, что это будет опубликовано в правильном месте.
Не время (я думаю?) Я меняю любой массив, они все установлены один раз вручную и просто зацикливаются. Я не уверен, что пытается (неявно?) Преобразовать
Информация при необходимости:
MSP430G2553 Вспышка 16 КБ ОЗУ 0,5 КБ
Спасибо за помощь
UPDATE: Хорошо HansPassant сказал мне, почему эта ошибка появляется. Но я все еще получаю переполнение ОЗУ (по-видимому, он не хранится во флеше?)
Еще одна вещь, которую я пробовал, вместо #define RON (Row ON) я объявила ее как const. (поэтому, когда был создан массив анимации, он был создан явно только с константами), я надеялся, что он сохранит его во флеше.
Здесь полный код при необходимости:

const int RON = HIGH;
const int ROFF = LOW;
