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.

Following Module structure is used:

Page Byte
1-10 x
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
