AuVidea HDMI-In boards

Hi, I am finishing off with a project which involved the purchase of a bunch of HDMI input 'shields' for the pi. For sale i have: 2x B101 Rev 4 with the I2S header & I2S cables 1x B102 Rev 4 with the I2S header & I2S cables All come in anti-static bags, with the ribbon cable. None of them have been ...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

Using ffmpeg just means the data gets written into a Linux pipe instead of writing to disk immediately. I'm now a little confused as to why the last change to yavta isn't behaving as I was expecting. Someone's borrowed my TC358743 board for the moment, so I'll have to reclaim it to do any more test...

Use SD card for OS on CM1

Hi,

I am shifting some code from a CM3L to a CM1, i noticed the CM1's only come with on-board eMMC, so I'm wondering if I have any option of running an OS off an SD card (processed by the CM1), or if i have to shift the OS onto the eMMC.

Thanks.

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

I tried to overclock the Raspberry Pi, but I still got dropped frames . I decided to check if the issue was with the SD card and tried to record the video in /dev/shm . I managed to have a mp4 video without dropped frames with yavta/ffmpeg :D So the bottleneck seems to be the sd card . Awesome. Wha...

CD0_SCL to GPIO45 CAM0_IO1 to GPIO2 CAM0_IO0 to GPIO3 6by9 can confirm, but i think these connections needed to be made to work with the new userspace app, though I'm sure he can confirm if...

The CSI2 bus has 5 dedicated pairs (4 data, 1 clock) back into the SoC for CAM1, and 3 pairs (2 data, 1 clock) for CAM0.

Re: Thoughts on a completed ADC HAT + Advice / feedback welc

Would this give that much better performance than the standard (cheap) USB sound cards? They are 16-bit 44.1-48 ksps. Wouldn't there be enough noise floating around on a Raspberry Pi that 16 vs 24 bits would be rather moot? Follow your dream but do you have some performance figures v. much less exp...

You need to tell the Pi what the ip of the nameserver (DNS) is. echo "nameserver 8.8.8.8" | sudo tee --append /etc/resolv.conf Sorry for bringing up a dead thread, but this is the only solution i can find that works after i've bumped my firmware using rpi-update.

Re: Fastest way to verify I2C write on flaky hardware

Bumb my own post.

I ended up going with some C routines, about a hundred times faster than using terminal commands like i2cset.
