[mythtv-users] IR transmitter WORKING

[pete]

After Hours of screwing with this I finally got it to work! (At least
it's flashing an led, yet to see if it actually will control my dish
receiver) :)

Following this guide:
http://www.mmdsi.com/mythtv/MythTV_DISH_IR_LED_TX_via_Modified_LIRC.html

Except for the following notes.

1. Unfortunately, I had somehow screwed up my kernel .config and I had
no idea what the original was supposed to be. So, I was getting
"unresolved symbols" whenever i compiled lirc. To fix, I used apt-get:	
	# export MYKERNEL=`uname -r` 	
	# apt-get --reinstall install kernel-source#$MYKERNEL

once this was completed, everything worked as expected.

2. add these lines to /etc/modules.conf:
	# Module for IR out
	alias char-major-72 ledxmit_serial
	below ledxmit_serial ledxmit_dev
	options ledxmit_serial irq=4 io=0x3f8
	pre-install lirc_serial /bin/setserial /dev/ttyS0 uart none
# I'm using com1

3.	# /sbin/depmod -a 
	# /sbin/modprobe ledxmit_serial
