带解码的红外头，接3.3V（1脚）地（6脚）输入（12脚）

以下操作使用ssh

增加模块
$ sudo vi /etc/modules
lirc_rpi

$ sudo modprobe lirc_rpi

确定驱动监视了“GPIO18”脚(引脚12号)
$ dmesg|tail
。。。
lirc_dev: IR Remote Control driver registered, major 251
lirc_rpi: module is from the staging directory, the quality is unknown, you have been warned.
lirc_rpi lirc_rpi.0: lirc_dev: driver lirc_rpi registered at minor = 0
lirc_rpi: driver registered!
input: lircd as /devices/virtual/input/input2
lirc_rpi: auto-detected active low receiver on GPIO pin 18

确定中断监视
$ cat /proc/interrupts
。。。
188: 3793 GPIO lirc_rpi

杀掉进程
$ pgrep -l lirc
348 eventlircd
1724 lircd

$ sudo kill 1724

看到数据序列，证明红外头有输出
$ mode2 -d /dev/lirc0

需要配置文件
$ sudo /etc/init.d/lirc start
[ ok ] No valid /etc/lirc/lircd.conf has been found..
[ ok ] Remote control support has been disabled..
[ ok ] Reconfigure LIRC or manually replace /etc/lirc/lircd.conf to enable..

录制配置，每个遥控器按钮，按下至少2个点，不超过10个点。
$ irrecord -d /dev/lirc0 ~/lircd.conf
。。。
Press RETURN now to start recording.
................irrecord: no data for 10 secs, aborting
irrecord: gap not found, can't continue

============没完成============
sudo mv /etc/lirc/lircd.conf /etc/lirc/lircd.conf.bak
sudo cp ~/lircd.conf /etc/lirc/lircd.conf

Afret reboot you can check LIRC:
irw

难道红外头还这么挑频率。
http://www.newark.com/jsp/search/produc ... KU=60K6999 居然ebay要9美元。美帝真这么有钱？傻逼啊。

有趣，持续关注一下
最好能发一下外围电路
是在开发版上搞得？内核是不是console=ttySX,监听了串口？

● sudo modprobe lirc
lirc_bt829 lirc_imon lirc_serial lirc_zilog
lirc_dev lirc_parallel lirc_sir
lirc_igorplugusb lirc_sasem lirc_ttusbir

居然没 lirc_ftdi。最常用的这种usb2uart的，多方便。http://www.huitsing.nl/irftdi/


难道真要加mcu，自己解码再去接串口转usb。。。。。

● sudo modprobe -r lirc_serial
● sudo modprobe lirc_igorplugusb

----------------------------------

● sudo lircd -n -H pinsys -d /dev/ttyUSB0
lircd: can't open or create /var/run/lirc/lircd.pid
lircd: No such file or directory

or in /etc/lirc/hardware.conf set these fields:

REMOTE_DRIVER="pinsys"
REMOTE_DEVICE="/dev/ttyUSB1"
REMOTE_SOCKET=""
REMOTE_LIRCD_CONF="pinnacle_systems/lircd.conf.pctv"
LOAD_MODULES="false"

and then run
/etc/init.d/lirc start
