| - | ====== 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:// | ||
| - | |||
| - | The board and schematic used for the ACAB installations are board/ | ||
| - | |||
| - | 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/ | ||
| - | 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/ | ||
| - | 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. | ||
| - | |||
| - | To program the RS485 bridge: | ||
| - | cd rs485bridge | ||
| - | make | ||
| - | make fuse | ||
| - | make program | ||
| - | ==== Bootloader ==== | ||
| - | |||
| - | The bootloader for the boards can be found at https:// | ||
| - | |||
| - | 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. | ||
| - | |||
| - | === Scripts === | ||
| - | ./ | ||
| - | Starts to send the select command to the bus. If a lamp with a bootloader reboots and has the corresponding id programmed, | ||
| - | it will get selected. If no id is supplied any lamp on the bus will get selected. After a lamp got selected, the scripts returns. | ||
| - | If a lamp got selected, it turns green. If a lamp is not selected it stays red. | ||
| - | |||
| - | ./set-m644p < | ||
| - | Sets the address of a lamp to < | ||
| - | multicast addressing. Example: set-m644p 5B | ||
| - | |||
| - | ./ | ||
| - | Loads the binary at < | ||
| - | |||
| - | ./ | ||
| - | Starts the program inside the selected lamp. This command always return with a timeout. | ||
| - | |||
| - | === Usage === | ||
| - | == If a new lamp needs to be configured and flashed == | ||
| - | Flash the bootloader to the lamp: | ||
| - | cd ubloader | ||
| - | make | ||
| - | make fuse | ||
| - | make program | ||
| - | | ||
| - | Compile the moodlamp firmware: | ||
| - | cd moodlamp-bus | ||
| - | make | ||
| - | |||
| - | Connect the RS485 bridge with the lamp and apply 24V power to the lamp. The lamp starts to light up red. | ||
| - | cd ubloader | ||
| - | ./ | ||
| - | ./set-m644p < | ||
| - | ./ | ||
| - | ./ | ||
| - | |||
| - | == If a single lamp needs to be flashed with new firmware == | ||
| - | Compile the moodlamp firmware: | ||
| - | cd moodlamp-bus | ||
| - | make | ||
| - | |||
| - | Start to select any lamp: | ||
| - | cd ubloader | ||
| - | ./ | ||
| - | | ||
| - | Connect the RS485 bridge to the lamp and apply 24V power to the lamp. The lamp turns green. | ||
| - | ./ | ||
| - | ./ | ||
| - | |||
| - | The lamps should now boot the new firmware. | ||
| - | |||
| - | == If a lamp is inside an installation and needs new firmware == | ||
| - | Compile the moodlamp firmware: | ||
| - | cd moodlamp-bus | ||
| - | make | ||
| - | |||
| - | Start to select the specific lamp | ||
| - | cd ubloader | ||
| - | ./ | ||
| - | |||
| - | Toggle the power of all lamps, The specified lamp turns green and the script returns. | ||
| - | |||
| - | Flash the new firmare: | ||
| - | ./ | ||
| - | ./ | ||
