Hello to all!
I'm trying to debug IR signals on a A20 based board with Arch Linux.
I'm trying to test if I'm able to read values from a remote IR control.
During boot I can recognise the ir as follow:
[ 2.478959] input: sunxi-ir as /devices/virtual/input/input0
Looking on the devices I get:
# cat /proc/bus/input/devices
I: Bus=0019 Vendor=0001 Product=0001 Version=0100
N: Name="sunxi-ir"
P: Phys=RemoteIR/input1
S: Sysfs=/devices/virtual/input/input0
U: Uniq=
H: Handlers=sysrq rfkill kbd event0
B: PROP=0
B: EV=3
B: KEY=ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff
fffffffe
(...)
Then, using this command I expect to see some signals:
# evtest /dev/input/event0
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100
Input device name: "sunxi-ir"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 1 (KEY_ESC)
Event code 2 (KEY_1)
Event code 3 (KEY_2)
(...)
Event code 247 (KEY_RFKILL)
Event code 248 (?)
Event code 249 (?)
Event code 250 (?)
Event code 251 (?)
Event code 252 (?)
Event code 253 (?)
Event code 254 (?)
Event code 255 (?)

I've tested a PHILIPS remote, no signal, and a SAMSUNG remote. On the
samsung remote I get values.
Event: time 1417698487.436218, type 1 (EV_KEY), code 2 (KEY_1), value 1
Event: time 1417698487.436227, -------------- EV_SYN ------------
Event: time 1417698487.959104, type 1 (EV_KEY), code 2 (KEY_1), value 0
Event: time 1417698487.959113, -------------- EV_SYN ------------
Event: time 1417698489.688749, type 1 (EV_KEY), code 2 (KEY_1), value 1
Event: time 1417698489.688757, -------------- EV_SYN ------------
Event: time 1417698489.989063, type 1 (EV_KEY), code 2 (KEY_1), value 0

Event: time 1417698491.069059, type 1 (EV_KEY), code 2 (KEY_1), value 0
Event: time 1417698491.069065, -------------- EV_SYN ------------
Event: time 1417698491.961707, type 1 (EV_KEY), code 2 (KEY_1), value 1
Event: time 1417698491.961715, -------------- EV_SYN ------------
Event: time 1417698492.269065, type 1 (EV_KEY), code 2 (KEY_1), value 0
Event: time 1417698492.269072, -------------- EV_SYN ------------
Also the device works. All remote are working used on their own devices.
My goal is to remplicate the signal of a remote command of an automatic
pellet stove. I would like to clone the signal. The remote works on the
stove, also it's not a remote issue. Is there a way to debug or to know if
the remote is incompatible? Reading the instructions it's defined as Infra
Red. Are there different IR signals? I've read that in some cases, values
sent above 255 are ignored. Could be the case? How in case to solve?
Thanks!
Simon
