проблемы с чтением EEEPROM, может и с записью

В общем :

Скетч использует 27126 байт (88%) памяти устройства. Всего доступно 30720 байт.
Глобальные переменные используют 996 байт (48%) динамической памяти, оставляя 1052 байт для локальных переменных. Максимум: 2048 байт

мало места ...

Ужимался где мог, в итоге EEPROM стал лажать почему-то.

Вот что получается при чтении данных (при загрузке контроллера)

time off       [0][-] 0
time on       [1][-] 0
time dt       [2][-] 0
H`% off       [3][-] 0
H`% on       [4][-] 44
H`% D       [5][-] 5
t`C on       [6][-] 28
t`C off       [7][-] 22
 

Прикладываю исходник, проблема в void options_get(), void options_put().
