| Post subject: | lirc problems. can't transmit to set top box |
Hi, I have built a mythtv box, but cannot get the IR transmitter to work. Specs: Knoppmtyh Release 5 F27 TV Card : Hauppauge Wintv Go Plus w/ remote (silver/dogbone?) Video Card: Nvidia The Myth TV part seems to be working fine. I can record and playback shows fine. I can even get the Hauppauge remote to work fine to change menus on mythtv. The irw commands work fine. However, I cannot get the IR transmitter to change the channels on the cable set top box. From what i understand, I do not have a serial transmitter. Most of the docs i see out there mention serial IR transmitter and requiring two lirc instances. Mine is part of the cable that comes out of the IR port on the Hauppauge card. Basically, the IR port on the card has a cable plugged into it that splits out to an IR receiver and an IR transmitter. The IR receiver works fine. I cannot get the IR transmitter to work. When I do a: Code: irsend SEND_ONCE DCT700 info I get this error: Code: irsend: command failed: SEND_ONCE DCT700 info irsend: hardware does not support sending When I run: Code: irsend LIST DCT700 "" That gives back a response. I'm thinking this command only looks at the /etc/lircd.conf command and not actually send anything to the IR transmitter. Syslog says: Code: Jun 2 15:36:42 mythtv lircd-0.8.3[2678]: accepted new client on /dev/lircd Jun 2 15:36:42 mythtv lircd-0.8.3[2678]: error processing command: SEND_ONCE DCT700 info Jun 2 15:36:42 mythtv lircd-0.8.3[2678]: hardware does not support sending Jun 2 15:36:42 mythtv lircd-0.8.3[2678]: removed client I tried this with lircd-0.8.2 and still had the same problems, so I decided to get the newest lirc and compile it myself. I compiled lirc 0.8.3 with: Code: ./configure --with-syslog --with-transmitter --with-driver=hauppauge ./configure --with-kerneldir=/usr/src/linux --with-moduledir=/lib/modules/2.6.18-chw-13/kernel/drivers/lirc/ --with-syslog --with-transmitter --with-driver=hauppauge install, something about not able to find crtbeginS.o It seemed to install okay since the logs are showing the newer version of lirc. I'm not that familiar w/ compiling programs. Is there a way to check if I've setup lirc okay? I have several entries in /etc/lircd.conf DCT700 is the cable box set top box model. I've put those codes in /etc/lircd.conf. lircd.conf also has entries for: blaster, Hauppauge, hauppauge_pvr, Hauppauge_350 From my understanding, the lircd.conf should have entries for the cable tv stb (IR transmit) and the remote control unit (IR receiver). It seems that I can specify anything (e.g., DCT700, junk, blah, etc.) in the IRSEND command and get the same error message. Some other specs: crw-rw-r-- 1 root video 61, 0 Jun 2 02:25 /dev/lirc0 srw-rw-rw- 1 root root 0 Jun 2 02:25 /dev/lircd ----------------------------- dmesg | grep lirc lirc_dev: IR Remote Control driver registered, major 61 lirc_i2c: chip 0x10005 found @ 0x71 (Hauppauge PVR150) ---> Not sure why it says PVR150. lirc_dev: lirc_register_plugin: sample_rate: 10 ------------------------------------ root@mythtv:/usr/src/mylirc/lirc-0.8.3# lsmod | grep lir lirc_i2c 12420 2 lirc_dev 16644 1 lirc_i2c i2c_core 20864 20 ivtv,lirc_i2c,i2c_ec,cx88_vp3054_i2c,cx88xx,saa7134_dvb,saa7134,ir_kbd_i2c,tda1004x,dvb_bt8xx,tuner,tea5767,tda8290,tuner_simple,mt20xx,tvaudio,bttv,i2c_algo_bit,tveeprom,i2c_i801 ----------------------------- # /etc/lirc/hardware.conf # LIRCD_ARGS="" START_LIRCMD=false LOAD_MODULES=true DRIVER="default" DEVICE="/dev/lirc0" MODULES="lirc_dev lirc_i2c" --------------------------------- root@mythtv:/usr/local/sbin/lircd --driver=?
