How avoid that updating library, eagle change value of the components
replaced to a default value?
In Eagle help I found:
If the VALUE command is used in the device edit mode, the parameters ON
and OFF may be used:
On: Permits the actual value to be changed in the schematic.
Off: Automatically enters the actual device name into the schematic
(e.g.74LS00N). The user can only modify this value after a confirmation.
If I set in device mode VALUE ON updating library eagle erase value
If I set in device mode VALUE OFF updating library eagle set default value.
Is possible change only symbol or package?
