May 29 03:35:32 <nerdboy> rcn-ee: are you thinking about adding cubox-i to your wiki stuff?
May 29 03:36:01 <nerdboy> imx6 quad with later vendor stuff than wand/udoo...
May 29 03:36:45 * nerdboy still waiting for more allwinner dtbs
May 29 16:10:06 <nerdboy> moin
May 29 17:12:08 * moto-timo half dreaming half awake
May 29 17:12:33 <moto-timo> dogsitting and they got excited by Mr. Possum last night
May 29 17:12:38 <moto-timo> zzZZZZZzzzzz
May 29 17:36:32 <Abhishek_> ds2: wanna have a look at the scope traces?
May 29 17:52:15 <ds2> Abhishek_: sure
May 29 17:53:12 <azizulhakim> av500: need some suggestion on what video compression can be used for slow data path like usb. the processing + transfer time should be around 1/4th of the total time required for uncompressed data.
May 29 17:53:23 <azizulhakim> I tried with RLE, but it wasn't effective
May 29 17:54:57 <ebadawy> azizulhakim: I recommend you ffmpeg
May 29 17:55:43 <azizulhakim> Thanks ebadawy :)
May 29 17:56:14 <ebadawy> you are welcome :)
May 29 19:16:22 <Abhishek_> ds2: uploading
May 29 19:17:00 <Abhishek_> ds2: https://drive.google.com/file/d/0B7U2bJEjkNeZWW04dERRVHkyWmM/view?usp=sharing
May 29 20:39:21 <ds2> got the trace of VSYNC with backlight on?
May 30 02:28:17 <Abhishek_> ds2: it's similar to HSYNC
May 30 02:28:30 <ds2> hmmmm that does't seem too bad
May 30 02:28:54 <Abhishek_> You able to see the 1Vpo noise on page 2 or 3?
May 30 02:28:55 <ds2> you saw about 1V P-P but from what I can tell it is like 2.8-3.8V
May 30 02:29:06 <ds2> yeah I saw that
May 30 02:29:33 <Abhishek_> And the spikes on the power supply look like ringing
May 30 02:29:55 <ds2> I am assuming some of that noise is artifacts from probing
May 30 02:31:13 <Abhishek_> I see
May 30 02:31:37 <ds2> i was schooled by an analog engineer and shown these special probes
May 30 02:31:52 <ds2> it is like a small tweezer with one side ground and other side signal
May 30 02:35:53 <Abhishek_> hmm
May 30 02:36:33 <ds2> I'd try lighting the backlight with an external supply next
May 30 02:37:44 <Abhishek_> I think I would add a snubber at the inductor to reduce the spikes
May 30 02:39:17 <Abhishek_> ds2: Could making the power trace thin be a problem (apart from current handling stuff)?
May 30 02:39:42 <ds2> yes
May 30 02:39:52 <ds2> but layout is a bigger thing
May 30 02:40:05 <ds2> there are current spikes and the area of the loop matters
