How the EEPROM is used:
|
||
|
|
|
||
|
|
|
||
|
|
First byte: shot counter offset
|
||
|
|
Second byte: hit counter offset
|
||
|
|
|
||
|
|
Each counter is a 32-bit unsigned integer (4 bytes). When it reaches a treshold
|
||
|
|
which is < 100,000 (the recommended EEPROM cell write limit) a new offset is calculated.
|
||
|
|
This way we ensure no cell is written over 100,000 times (assuming the EEPROM is
|
||
|
|
new) and you can click away until you run out of EEPROM.
|
||
|
|
|
||
|
|
|
||
|
|
For initialisation set ShotCounterOffset and HitCounterOffset to
|
||
|
|
different values. Keep in mind that Offset * 4 must not be greater than
|
||
|
|
the amount of available EEPROM!
|
||
|
|
|
||
|
|
Shot/HitCounterInitial defines the default value to write for
|
||
|
|
each counters.
