lyc - Linux Yamaha receiver control (over serial / RS232 interface)

Yamaha RX-V3800 and some older models like DSP-AX1 are great AV-Receiver, but unfortunately they have no control / web interface to manage it from outside. With a USB-Serial adapter connected to the reciver RS-232 interface, a computer or router and lyc you can control the reciver. In addition, a web interface can be created with wlyc to provide a web access to all network devices like PC, smartphone or tablet.

GitHub repository
https://github.com/panticz/lyc

Download binary
http://dl.panticz.de/lyc/i386/lyc - i386 compiled
http://dl.panticz.de/lyc/ar9132/lyc - Atheros AR9132 (TP-LINK TL-WR1043ND / TL-WDR4300 router)

HowTo compile and run
1. download lyc.c and Makefile
2. compile with: make
3. set up USB Serial adapter http://www.panticz.de/USB-Serial-adapter
4. run command:

./lyc input dvd
./lyc volume up

Run on OpenWrt router
1. download sources
2. comile with
make mips
4. copy lyc to OpenWRT router:

scp lyc root@OPENWRT_IP:/root/lyc

5. login to root@YOUR_OPENWRT_IP
6. download wlyc (OpenWrt wget can not access https, use http redirection)

wget -q http://dl.panticz.de/wlyc/wlyc -O /www/cgi-bin/wlyc
chmod 755 /www/cgi-bin/wlyc

7. Open im broser:
http://OPENWRT_IP/cgi-bin/wlyc
Example: http://ROUTER_IP/cgi-bin/wlyc?p1=input&p2=dvd
