При вызове LcdStr(FONT_1X, s, NORMAL); пишет "function parameter 2 not compartible with its declaration"
Хочу отметить кое-что. Еще до того, как я начал пытаться читать и писать в EEPROM я не мог вывести на экран даже обычную строку, хотябы через кавычки. Помогло, когда в объявление функции void LcdStr ( LcdFontSize size, char *dataPtr, LcdPixelInverse inverse ) Я вместо char написал char __flash.
Однако, прочитанную из EEPROM строку так не выведешь, ошибку типа выдает. Я убрал flash.
Как мне вызывать получившуюся в итоге функцию, чтобы:
1. Выводить строки из flash.
2. Выводить строки из EEPROM
3. Выводить значения переменных, которые им присваиваются в ходе работы программы.
p.s. Текст некоторых функций я убрал, так как сообщение не отправляется из-за большой длины. В аттаче все файлы.
