rf-bitbanger ============ Simple tools for experiments with bitbanged RF communication. License: GPL v2. See the COPYING file. Disclaimer ---------- Do not use the tools and code in situations where operation or lack of operation may result in property damage, personal injury, or death. Rules and regulations may control the use of RF communication at a national level. Do not use rf-bitbanger tools or code to break applicable laws and regulations. rfbb driver ----------- LIRC style device driver that transmits and records pulse and pause-lengths using gpio. Uses code from lirc_serial.c by Ralph Metzler et al. See rfbb_hardware.txt for information on how to connect the GPIO to a common 433 MHz TX module. To build on target: > cd rf-bitbanger/rfbb > make KERNELDIR=~/linux > sudo insmod rfbb.ko Check for device node and add if not already there using dialout as group: > ls -al /dev/rfbb > dmesg > sudo mknod /dev/rfbb c 252 0 > sudo chown root:dialout /dev/rfbb > sudo chmod g+rw /dev/rfbb rfbb_cmd -------- rfbb_cmd is a small tool, that acts as a remote control for switches that use simple unidirectional communication based on OOK (On Off Keying) modulation on a 433 MHz carrier. rfbb_cmd uses the linux rfbb kernel driver. To build: > cd rf-bitbanger/rfbb_cmd > make > sudo make install A simple test on an old style (not selflearning) NEXA/PROVE/ARC set to group D, channel 1. > rfbb_cmd -d /dev/rfbb -i RFBB -p NEXA -g D -c 1 -l 1 > rfbb_cmd -d /dev/rfbb -i RFBB -p NEXA -g D -c 1 -l 0 Issue rfbb_cmd --help to get more information on supported protocols and options. Note! All protocols might not be fully tested due to lack of receivers and time :). rfcmd ----- rfcmd is a another small tool that acts as a remote control for switches that use simple unidirectional communication based on OOK (On Off Keying) modulation on a 433 MHz. rfcmd use tellstick (www.telldus.se) as transmitter instead of rfbb. To build and test: > cd rf-bitbanger/rfcmd > make > sudo make install > rfcmd /dev/ttyUSB0 NEXA A 1 1 > rfcmd /dev/ttyUSB0 NEXA A 1 0 Issue rfcmd --help to get more information on supported protocols and options. /Last update: 2012-07-03 Tord Andersson
