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
| Page | Byte |
| 0 | 64 |
- This byte represents the hour (time) of the last system startup.
| Page | Byte |
| 0 | 65 |
- This byte represents the minute (time) of the last system startup.
| Page | Byte |
| 0 | 66 |
- This byte represents the second (time) of the last system startup.
| Page | Byte |
| 0 | 67 |
- This byte represents the day (date) of the last system startup.
| Page | Byte |
| 0 | 68 |
- This byte represents the month (date) of the last system startup.
| Page | Byte |
| 0 | 69 |
- This byte represents the year (date) of the last system startup.
| Page | Byte |
| 0 | 70-72 |
- 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).
Data output modules (Page 1-10)
- Page 1 – 10 -> Contains data of the output modules, 32 bytes per module, 8 modules per page, 10 pages (80 modules maximum, 640 outputs -> 0-639)
| Page | Byte |
| 1 | x |
- This page is entirely used for output module 0-7:
- * Module 0: Byte0..31
- * Module 1: Byte32..63
- * ...
| Page | Byte |
| 2 | x |
- This page is entirely used for output module 8-15:
- * Module 8: Byte0..31
- * Module 9: Byte32..63
- * ...
| Page | Byte |
| 3 | x |
- This page is entirely used for output module 16-23:
- * Module 16: Byte0..31
- * Module 17: Byte32..63
- * ...
...
| Page | Byte |
| 10 | x |
- This page is entirely used for output module 72-79:
- * Module 72: Byte0..31
- * Module 73: Byte32..63
- * ...
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
Data shutter modules (Page 11-14)
- Page 11-14 -> Contains the data of the shutter status
| Page | Byte |
| 11-14 | 0-255 |
- Page 11 Byte 0-3: Information regarding Shutter 0

- Every Roller/Shutter has 4 bytes:
- First byte: Shutter status
- BIT0: =1-> direction UP, =0-> direction DOWN
- BIT1: =1-> shutter is locked, =0-> shutter is unlocked
- Second byte: Current Timer up value
- Third byte: Current Timer down value
- Fourth byte: Current shutter position
- First byte: Shutter status
