Introduction
The AIO has an onboard FRAM connected via I2C to the DSPIC33E (The Master). FRAM is used to keep track of the real-time change, Eeprom is used to store the settings. This document describes the FRAM memory locations used.
General Configuration Bytes (Page 0)
- Page 0 -> General data
- This byte represents the hour (time) of the last system startup.
- This byte represents the minute (time) of the last system startup.
- This byte represents the second (time) of the last system startup.
- This byte represents the day (date) of the last system startup.
- This byte represents the month (date) of the last system startup.
- This byte represents the year (date) of the last system startup.
- These 3 bytes represents the number of hours this system is ON. Byte 70 is the MSB (Most Significant Byte), Byte 72 is the LSB (Least Significant Byte).

Following Module structure is used:
- Byte 0 (or 32 or 64 ...): Output state of this output (8 outputs, 1 bit per output, 0=OFF, 1=ON)
- Byte 1 (or 33 or 65 ...): Dimmer value of output 0 of the concerning module
- Byte 2 (or 34 or 66 ...): Dimmer value of output 1 of the concerning module
- Byte 3 (or 35 or 67 ...): Dimmer value of output 2 of the concerning module
- Byte 4 (or 36 or 68 ...): Dimmer value of output 3 of the concerning module
- Byte 5 (or 37 or 69 ...): Dimmer value of output 4 of the concerning module
- Byte 6 (or 38 or 70 ...): Dimmer value of output 5 of the concerning module
- Byte 7 (or 39 or 71 ...): Dimmer value of output 6 of the concerning module
- Byte 8 (or 40 or 72 ...): Dimmer value of output 7 of the concerning module
