Hello,
I am working on a project to control lights and devices from the internet.
My goal is to fit a 433mhz transmitter in a wrt54gl to control some wireless powerswitches. (http://www.gadgetgarden.nl/archives/gggkktt_klik0.jpg)
These switches have a 433mhz receiver and come in different types (on/of , dim , sunscreen (up/down) )
thanks to a dutch forum ( http://gathering.tweakers.net/forum/lis … es/1077675 ) i now have a 433mhz transmitter hooked op to a serial port.
and a config file for LIRC. It's working fine with WinLIRC and this config file.
The second stage was the linksys,
I bought a WRT54GL, installed Openwrt, and used 'esteevens' LIRC package from this thread http://forum.openwrt.org/viewtopic.php?id=735'
I also had to install libgcc (ipkg install libgcc) for it to work
if i send the 'irsend SEND_ONCE klik J1ON' command the DMZ Led starts flashing and the goes off again.
So far so good.
So i took out my soldering iron and removed the DMZ led. then i connected a wire to GPIO7. (the pin closest to the WLAN led of the DMZ Led)

And added 2 wires to power the 433mhz transmitter from the serial port header, ( pin 1 and 10)
I attached a Led on the wire from the GPIO 7 and the Ground, But somehow the led is now INVERTED.
if i execute 'gpio enable 7' the led goes ON, en 'gpio disable 7' turns it off again.
Same goes for LIRC, if i start lirc the led goed on, while sending the command it flashes rapidly and the stays on again.
I connected the 433mhz transmitter anyway but of course it ont word because teh signal is now inverted.
So i have the following Questions
1. Did i used the correct pins, or do i need to solder to other points on the wrt54gl
2. Can i invert the signal in lirc, (winlirc has this option but i can't find this option in LIRC)
3. With which language can i execute shell commands from a webpage in OpenWRT, PHP is probely to big for its memory ? (Third stage, creating a WebUI)
