ROT Installation guide

mounting the board

Make sure there is no gap left. Press the two PCB so you can hear/feel a litlle "click" ...

RPi - 512MB special note:

At the 512MB version board of RPi the connector handles have become very big. The hole provided at the ROT is 2.9mm only!! Therefor the handle needs to be removed:

UPDATE: The newest RPi charge even uses a 3mm thick connector. This is about 0.1mm too big for the slot at ROT. In case you got one of those RPis you must rasp away some micrometers of ROTs slot to make it fit.

System

The i2c-bus number used below might differ depending on yr RPi version or kernel

TPUART - EIB/KNX bus access

You need to free-up the serial line used by ROT remove any references to ttyAMA0 in:

/etc/inittab - comment or delete: T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
/boot/cmdline.txt - and reboot!

RPI3 + JESSIE:

add to:
/boot/config.txt
dtoverlay=pi3-miniuart-bt

change:
/boot/cmdline.txt
dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

commands to issue:
sudo systemctl stop serial-getty@ttyAMA0.service
sudo systemctl disable serial-getty@ttyAMA0.service
sudo reboot

then:

sudo -u pi eibd -i -D -T -S -e 1.1.251 tpuarts:/dev/ttyAMA0

(For Banana Pi the device is called: /dev/ttyS2)

ETS configuration to access ROT - use SCAN-button to find IP-address:

Onewire

echo ds2482 0x18 > /sys/bus/i2c/devices/i2c-0/new_device

use owhttpd or similar to access bus

EEPROM

echo "24c02 0x50" > /sys/class/i2c-adapter/i2c-0/new_device

try:

hexdump -C /sys/bus/i2c/devices/0-0050/eeprom

RTC

echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-0/new_device

use: hwclock

compiling eibd on RPi

wget http://www.auto.tuwien.ac.at/~mkoegler/debian/pool/main/p/pthsem/pthsem_2.0.8.tar.gz
tar -xzvf pthsem_2.0.8.tar.gz
cd pthsem-2.0.8
./configure
make install
ldconfig -v

cd ..

wget http://www.auto.tuwien.ac.at/~mkoegler/debian/pool/main/b/bcusdk/bcusdk_0.0.5.tar.gz
tar -xzvf bcusdk_0.0.5.tar.gz
cd bcusdk-0.0.5
./configure --enable-onlyeibd --enable-tpuarts --enable-eibnetip --enable-eibnetipserver
make install
