Tiny vs. C8051 ????
Jim, Indeed, much weight has to given to the familiarity of the tools and the device. If one device has hardware advantages over another that needs to be weighed against the time/...

Using EEPROM with variables in AVR
simplify eeprom_update_dword(( uint32_t *)EE_P_P,P_gain_room); eeprom_update_float double EE_P_gain_room = eeprom_read_dword((uint32_t*)EE_P_P); eeprom_read_float
