Minix original ir remote has a few buttons. Thus we want to need a lot fuctions with remote. I will explain add new remote on x8hplus. I use new remote (ir)
We can use old amlogic box remotes. for this
1-need to be rooted device
2-terminal emulator
3-ESexplorer
**********************
Code:
* dmesg :     Where you will get your information
* Remotecfg :     Used to load new Remote.conf files and checking for errors in them
* /system/etc/Remote.conf :     File which maps your remote scan codes to linux key codes
* /system/usr/keylayout/Vendor_0001_Product_0001.kl :     File which turns Linux Key codes to Android Key codes for the Amlogic IR device
open ESexplorer
goto and open /system/etc/remote.conf
after modifiye this line
Code:
#amlogic NEC remote
factory_code    = 0xfe010001
work_mode          = 0
repeat_enable = 1
repeat_delay = 40
repeat_peroid = 50
release_delay    =    100
debug_enable     = 0
to
Code:
#amlogic NEC remote
factory_code    = 0xfe010001
work_mode          = 0
repeat_enable = 1
repeat_delay = 40
repeat_peroid = 50
release_delay    =    100
debug_enable     = 1
after we can look remote scan codes

start to terminal
write su
after
write dmesg -c (for clean dmesg)

- Click remote buttons respectively.

write dmesg | grep "code is 0x"

see the following code for the button (in the example, OK)
Wrong custom code is 0xaabbcccc
scan code is bb
for example: open remote cfg
you can look below
key_begin 
0x47 105 #DPAD_LEFT
our remote send scancode 0x47 to ourbox 
ourbox known with remote.conf (What is mean 0x47) key 105
