Доброго времяни суток !
Хочу освежить компилятор. Скачал пакет avr-gcc-4.7.2-mingw32 , как здесь посоветовали. Уже установлен WinAVR-20100110. Обычно пишу и компилирую из под встроенного редактора pn.exe .
Не хотелось бы эксперементировать в слепую, тем более назначение практически всех программ я незнаю. Как мне обновить компилятор ? Просто скопировать содержимое папок с заменой ?

Просто скопировать содержимое папок с заменой ?
Да. Если боитесь, сделайте резервную копию папки WinAVR.
Вписать в path путь на C:\avr-gcc-4.7.2-mingw32\bin (перед winavr-овским). Но лучше вместо. tools я оставляю атмеловскую сборку (make.exe оттуда, например).
скопировал, теперь при обьявлении таблице во flash-памяти :\
Чего не так ?
Код
uint8_t tabl_rb1[] PROGMEM={0,2,3,7,3,1,5,4,6};
ругается :Код
error: variable 'tabl_rb1' must be const in order to be put into read-only section by means of '__attribute__((progmem))'
Чего не так ?

Оно хочет чтобы вы сделали массив константным.

const uint8_t tabl_rb1[] PROGMEM={0,2,3,7,3,1,5,4,6};

да я поставил const перед таблице , скомпилировал, выдало несколько новых ругательств:Код
const uint8_t tabl_rb1[] PROGMEM={0,2,3,7,3,1,5,4,6};

FlashRGB2.h:22:1: warning: optimization may eliminate reads and/or writes to register variables [-Wvolatile-register-var]
ну с этим более менее понятно , почему только оно раньше не вывдавалась и что с этим делать ? как я понимаю нужно включить указанный ключик
Вообще протокол компиляции меня както напряг.
