-====== ACAB Setup Instructions ======
-The goal of this page is to gather all information needed to set up an ACAB installation from the ground up.
-===== Hardware =====
-The currently used hardware can be found at https://github.com/schneider42/moodlamp-rf
-The board and shcematic used for the ACAB installations are board/buslamp.{brd,sch} and are designed with EAGLE.
-The hrdware uses RS484 to signal data to the lamps and a 24 V to 28 V supply voltage. Both the RS484 signal and the supply voltage
-are crried on a single cable. To keep the cost down standard Cat 5 network cables are used.
-To communicate with the host computer, the RS484 interface has to be adapted to another interface. The device described by board/ub.{brd,sch}.
-It is intended to be used with our IPv6 home automation project, but can also be used to act as an USB to RS485 bridge.
-===== Software =====
-==== RS485 Bridge ====
-The software for the RS485 bridge can be found inside the rs485bridge/ directory. It translates frames from a normal serial connection to
-the RS485 bus used by the system. When used with the device mentioned above, it can be used to connect an ACAB installation to a PC.
-==== Bootloader ====
-The bootloader for the boards can be found at https://github.com/schneider42/moodlamp-rf inside the ubloader/ directory.
-The bootloader is used to update the firmware of the lamps while they are inside an installation and therefore inaccessible.
-It consists of a small bootloader program, running on the lamps, and a set of Python and bash scripts to upload new firmeare to the lamps.
-The bootloader can upload new firmware to a lamp and program arbitrary parts of the EEPROM. To single out a lamp on the bus and only programm a single one,
-the bootloader can be used to compare an arbitrary section of the EEPROM to data transmitted via the bus.
-The scripts use this feature to select a single lamp after all lamps performed a power on reset.
-To flash lamps which have not yet a uniqe EEPROM content, the bootloader can be forced to consider the lamp selected.
-=== Usage ===
-  - Program the RS485 bridge
-    - cd rs485bridge
-    - make
-    - make fuse
-    - make install
-  - If a new lamp needs to be flashed
-    - Flash the bootloader to the lamp:
-      - cd ubloader
-      - make
-      - make fuse
-      - make install
-  - Compile the moodlamp firmware:
-    - cd moodlamp-rf
-    - make
-  - If you want to set up a single lamp that has not yet been configured:
-    - Connect the RS485 bridge with the lamp and apply 24V power to the lamp. The lamp starts to light up red.
-    - cd ubloader
-    - ./select-m644p
-      - This command selects any lamp connected to the system
-    - ./set-m644p $hexadecimal_number
-      - Replace $hexadecimal_number with a uniqe hexadecimal number greater than 0x10. Numbers smaller than 0x10 are reserved for multicast addresses on the bus
-      - This command sets the address of the lamp on the bus to this number
-    - ./flash-m644p
-      - This command loads the firmware from the moodlamp-rf directory and sends it to the lamp.
