Infrared remote control version of NetEase Yun music player based on raspberry pie. The following is a schematic diagram of the remote control keyboard:

CH- CH CH+ > | |-+ EQ 0 100 + 200 + 1 2 3 4 5 6 7 8 9

Musicbox uses the current user's favorite playlist as the channel list. CH-/+ represents switching to the first / next channel. Press the CH key to broadcast the relevant information of the current channel, and double press the CH key to restart musicbox. For switching to the top / next track, press the | key to play / pause the current track. + /-is the volume adjustment key. Press EQ to broadcast information about the current repertoire. If a single / a pair press the 0 to 9 keys, the corresponding ordinal tracks will be played. For example, if you press 6 alone, you will play the track with ordinal 6; for example, if you double press 7, you will play the repertoire with ordinal 77. Press 100 + to broadcast the current date and 200 + to broadcast the current time.

VCC connected to 3.3v pin, GND grounded, IN connected to GPIO 18.

Open the file / boot/config.txt, find the configuration that starts with dtoverlay, read the comments, and modify it as follows.

Dtoverlay=lirc-rpi,gpio_in_pin=18

Infrared default output is 18 pins, after the above, gpio_in_pin=18 can not be written. If the infrared receiver head is connected to other pins, the corresponding pins need to be modified.

After installing the lirc software.

$[sudo] apt-get install lirc

Edit the file / etc/lirc/hardware.conf to modify some of the contents as follows. After modification, save and restart the system, and use the ls / dev/l* command to check whether the infrared device works, and if there is a lirc0, it can be used.

LIRCD_ARGS= "- uinput" DRIVER= "default" DEVICE= "/ dev/lirc0" MODULES= "lirc_rpi"

To test the infrared reception function, first use the command / etc/init.d/lirc stop to shut down the LIRC software, and then execute the following command.

$[sudo] mode2-d / dev/lirc0

Finally, overwrite the file musicbox/lircd.conf to the corresponding file of the LIRC software

$[sudo] cp ~ / lircd.conf / etc/lirc/lircd.conf installation self-startup script

Copy the file musicbox to the directory / etc/init.d/

$[sudo] cp musicbox / etc/init.d/

Modify the execution permissions of the copied file

$[sudo] chmod 755 musicbox

Add boot startup item
