HiFiLOGIX 0.2.0 (Fix 1)
|

|
!!! IMPORTANT NOTICE !!!
|
|
|
|
As of 0.2.0 EEPROM support is no longer considered to be beta and has been
|
|
fully integrated in to the main build. You should be aware of the following:
|
|
|
|
It uses EEPROM addresses 1020 - 1023
|
|
It will erase any data you may have there during the initilization routine.
|
|
|
|
If your EEPROM is smaller, or you don't want to use 1020 - 1023; then you'll
|
|
need to change their #define to match what you want/need.
|
|
|
|
Pin 2 is used for the hardware interrupt trigger that writes the data. It's
|
|
set to run fall. This will be done in hardware by isolating a capacitor for
|
|
the Arduino and tying pin 2 to the part of the power supply that will drop
|
|
first. The reserve current should last long enough to update the values before
|
|
draining.
