- SYNOPSIS
- elf2bin [-s hexadr] [-e hexadr] [-w] [-r] [file]
|
|
<

- DESCRIPTION
- Copies the Elf memory to a binary file (or stdout) on the Raspberry Pi. The Raspberry Pi GPIO is used as interface to the Cosmac Elf SBC (e.g. Elf Membership Card parallel port). The generated data is written to the standard output stream or to a file. Caution: Overwrite file if it exists. Use > for redirecting (save the file) or | for piping to another command (e.g. hexdump). All switches an the Elf Membership Card have to be on the up position except for the READ switch, the READ switch has to be on the down position.

- OPTIONS
- Non argument options that are duplicated on the command line are not harmful. For options that require an argument, each duplication will override the previous argument value.
- -s hexadr
- start address in hex (0 is default)

- DESCRIPTION
- Copies the content of binary file on the Raspberry Pi to Elf (Membership Card) memory. The Raspberry Pi GPIO is used as interface to the Cosmac Elf SBC (e.g. Elf Membership Card parallel port). Use < for redirecting or | for piping from another command. All switches an the Elf Membership Card have to be on the up position except for the READ switch, the READ switch has to be on the down position.

- DESCRIPTION
- Controls the mode, sets data switches and gets LED data of an Elf (Membership Card). The Raspberry Pi GPIO is used as interface to the Cosmac Elf SBC (e.g. Elf Membership Card parallel port). If a command is missing, the default command is then get. All switches an the Elf Membership Card have to be on the up position except for the READ switch, the READ switch has to be on the down position.

-
- load
- sets the mode to load (WAIT and CLR active, is equivalent to switches down)
- run
- sets the mode to run (WAIT and CLR inactive, is equivalent to switches up)
- wait
- sets the WAIT to active (is equivalent to switch down), option -n inverts the WAIT to inactive (is equivalent to switch down)
