Overview
The Likoboard ([1]) is an Open Hardware pcb that can be used to interface with an Elphel camera over USB.
Some quick specs:
- Based on GNU GPL library MyUSB
- Compiled by GNU GCC
- Can be upgraded by standard USB DFU tools
- Atmel at90usb162 USB chip in QFN 5mmx5mm package
- Atmel/Quantum QT1106 touch sensor in QFN 5mmx5mm package
- World smallest 16MHz quartz
- Micro buzzer
- BC807/817 500mA transistors
- Special sensor layout routed on one side of PCB for human touch control
- Secured debug connector
- Size: 39mm x 16mm x 4 mm
Compiling
You can get the latest package including binaries for libusb, libhid, liblikoboard and php_likoboard with:
git clone git://ocube.ath.cx/likomapper-bin.git
and install it on the camera with something like:
cd likomapper-bin tar c . | ssh root@cam tar xv -C /
To build binaries from source you need:
- the axis crisv32 compiler,
- libusb-0.1.11 from sourceforge (version 0.1.12 is broken)
- libhid-svn from http://libhid.alioth.debian.org/ I used revision 634. (svn co svn://svn.debian.org/libhid/trunk libhid-svn)
- liblikobard (git clone git://ocube.ath.cx/liblikoboard.git)
- php_likoboard (git clone git://ocube.ath.cx/php_likoboard.git)
You will need to modify some "configure.in" so that crisv32 is accepted as host type (eg adding "*" after "cris") before ./configure works, and some "libtool" script so that crisv32-axis-linux-gnu-ranlib is found (adding path) before make install works.
You can use crisv32-axis-linux-gnu-strip to strip the resulting binaries.
Build libusb-0.1.11 with :
. /?/elphel.env ./configure --host=crisv32-axis-linux-gnu --build=i686-pc-linux-gnu --prefix=/usr/local/crisv32 --with-pic make make install
Build libhid-svn with:
. /?/elphel.env ./configure --host=crisv32-axis-linux-gnu --disable-swig --with-pic --prefix=/usr/local/crisv32 make make install
Build liblikoboard with:
. /?/elphel.env ln -sf Makefile.crisv32 Makefile make make install
Build php_likoboard with:
. /?/elphel.env export LDFLAGS=-llikoboard ./autogen.sh phpize make cp modules/php_likoboard.so /usr/local/crisv32/usr/local/lib/php/extensions/no-debug-non-zts-20060613/ .
Configuration
The main configuration file is located at
/etc/conf.d/likomapper.conf
Setting DAEMON=0 in /etc/conf.d/likomapper.conf allows you to run likomapper from the command line, without patching the firmware.
