| Post subject: | LIRC and Home Brew IR Blaster Not Working |
Hello, I have just brought online my installation of MythTV. For the most part all is working however I cannot get LIRC to work as a second instance to change channels on my Cable box via a homemade IR Blaster. Some background: I have a P4 w/ 1 Gig Ram 2x 80 Gig SATA w/ 3Ware Raid 1 (OS) 1x 250 Gig SATA for Myth Content nVidia GForce 5700 w/ 256 Mb Hauppauge PVR-250 Fedora Core 2 w/ most recent patches running 2.6.9-1.6 kernel. My cable box is a Scientific Atlanta Explorer 4200 I have downloaded and successfully compiled a second instance of LIRC using JDS' excellent howto and script located here: http://losdos.dyndns.org:8080/public/my ... _LIRC.html My problem is that my IR Blaster does not change channels. My homemade IR Blaster seems to work -- at least when I put a normal led and tell it to change channels it blinks. Also with an IR LED (Several actually) and using the "Camera Trick" using the display of a digital camera see that the LED is blinking. I am using lirc-0.7.0pre8 and made sure I uncommented the two lines in the myth-ledxmit.sh script. All compiles and makes seem OK. I am using the code from SA2000 in my /etc/ledxmit.conf. Several have verified that the SA2000 is compatible with the SA4200HD. Only thing I can see that may be casuing the problem is the following error I get when I load the modules (ledxmit_dev & ledxmit_serial) for the second instance of LIRC. Badness in sleep_on_timeout at kernel/sched.c:3022 [<022a689e>] sleep_on_timeout+0x5d/0xd0 [<021171fc>] default_wake_function+0x0/0xc [<0211ea6f>] __request_region+0x84/0x8d [<42e708e7>] init_port+0x1f0/0x254 [ledxmit_serial] [<42e710f7>] init_module+0x33/0x89 [ledxmit_serial] [<0212e8e0>] sys_init_module+0x116/0x238 ledxmit_serial: auto-detected active high receiver ledxmit_dev: ledxmit_register_plugin:sample_rate: 0 I found one article googling that discusses this, however after applying the patch provided and recompiling the problem persists. Here is the link to the article: http://lists.atrpms.net/pipermail/atrpm ... 01294.html Any assistance in this matter is appreciated. Sincerely, Babak Pasdar bpasdar1 !at! yahoo.com |

I have had no problems with the circuit and a dct2000 cable box but did see that error with an early version of lirc. I got the cvs version and that worked I recommend you do the same. I used http://members.cox.net/rwraithr/IRBlaster_Howto.txt instead following his steps exactly this involves a bunch of edits of major devices. His script does help. If this doesnt help I could tar up my files for you. Good luck James |
