Fix - repeated keys bug

Recommended Posts

Hello all,

If you get sometimes phatoms or repeated key press from OpenElec try just to change your XBMC TV resolution to 60Hz instead of 50Hz !
For me this is the only permanent fix for getting Flirc usable with my RPi and my Phillips Full HD TV...

Hope this will help.

6 monthes to find this tip !

Enjoy

Yet another try ?

On RPi, with OpenElec, I just add to cmdline.txt the

dwc_otg.fiq_fsm_enable=1

as https://github.com/OpenELEC/OpenELEC.tv/issues/3091

Now, after some rebots my remote still press normaly (without phantom and repeated key)

 

Hope it is the good tip this time !?...

I try another (personnal) hack...

will give feedback in few days if results stay correct !!!

 

:wacko:

I have to take some steps to have FLIRC working fine, without any keypress bug !

- Put my RPi and FLIRC under the TV table

- Put a black scotch on the front of the IR of FLIRC

- All are on a powered HUB

 

Now it's okay, but It's not really explainable...

 

Edited : Do not work for a long time !

:unsure:

We have a "Troubleshooting keyboard presses" section of our knowledge base. https://flirc.zendesk.com/hc/en-us/sections/200669959-Troubleshooting-Keypresses

Does this help?

 

Already tested but without great success...

 

The next test/solution : use the FW V3.3 !

 

;)

 

Thanks

 

The version V3.3 help to suppress most of phantom keys.

There are still some issue with still press key when waking up the RPi but this is mainly usable.

 

Thanks...

This subject is still open.

 

It is a RPi / IR / TV problem.

Let me explain my latest results.

 

I use an RPiB with the latest up to time version of OpenElec.

It is controlled with an USB FLIRC plug and XBox IR Remote.

I have some issues from the beginning of my tests, less with the FLIRC Firmware upgrade, but still some, sometimes.

I have also an A/V Amplifier between the RPi and the TV.

A/V is a Cambridge AZUR-351R recently bought and TV is a 42PFL9603H (2008).

I have tested hardware possible issues by switching versions of differents model of power supply, HDMI cables, connecting directly to TV, powering from USB HUB, differents remotes same PowerSwitch source connection for all the peripherals (RPi, A/V, TV).

I have tested all, or not so far all, differents conbinations of parameters from bootloader to OpenElec and XBMC.

remote console logging give no intersting results.

 

The only fact is, that the remote used to control the RPi is disturbed by the TV.

If the TV is powerd ON, I may get double OpenElec click like issue with single click only on my IR remote.

 

If I try to hide the TV IR sensor, or if I power OFF the TV (with the navigation sound activated in XBC to verify the issue because no TV for HTPC installation is not a very confortable solution...) then the click seems to be correct.

 

I get some tries to switch to another ARM manufacturer solution, actually giving a chance to the OdroidC1, but this one has a great bug unresolved for now, HDMI Flicker/Drop of video signal and sometimes sound.

But it is another adventure in the land of the ARM debugging life.

 

So, I read a lot about IR issues and troubleshout.

I search also about the HDMI troubleshout subjects.

 

A lot of questions, from a long time, but no correct results nor valuable explanations.

 

I discover that the Modern Flat Panel TV had an hidden advanced factory menu.

Why am I not surprised ?

I get into the Philips advanced parameters and choose to get a try of disabling CEC (2 parameters intially ON, advanced CEC and CEC, where modified to OFF).

I get my OdroidC1 some tests, but still not verry successfull.

Factory IR Remote of the C1 work out of the box, the OdroidC1 had an integrated IR sensor and the default keymap is XBMC.

 

I get better results yesterday with switching video of the C1 to 720p.

After some hours of TV watching without any problems I fell that I may get a workaround.

 

But back to TV today, I get again some HDMI/VIDEO drops.

 

I return back to the primary HTPC (the RPi with FLIRC) and get a try.

 

If you have read all this long feedback report, then you may hope the end of the suspens.

 

What ?!

No more phatom key, no still pressed issue ?

 

Is it a CEC issue (disabling it in the RPi in OpenElec is not of any help) ?

 

I will give more tests and may complete (again) this post if needed.

But obscoured, closed, hidden, code may have been responsible, again, of a huge lost of time, and not for me only I suppose.

 

Hopes this may help anybody to, simply, watch his/her video and get a popcorn time been a pleasure !

Enjoy...
