Re: HDMI and official dsi screen at the same time? Pi2

Finally got this to work, desktop now on official 7" screen, and HDMI. I have delivered the Pi to my children, so can't remember exactly what I did, I think I did apt-get install libxinerama1 Which seemed to be already installed, but is now set as 'manual install' rather than automatic. Found the me...

Re: Raspberry Pi ham repeater

Re: HDMI and official dsi screen at the same time? Pi2

More info: Original monitor was DVI, TV is Polaroid. If I power up just the Pi, either screen displays the desktop. Powering the official screen, I only get the rainbow splash on the bigger screen and no further than that - official screen is ok. On the iiyama DVI, and the TV have tried /opt/vc/bin/...

Re: Raspberry Pi High Quality Camera Launched !

That distance is from the sensor plane to the front of the locking ring.
That's useful, but not quite what I asked, specifically from the sensor plane to the *rear* of the board.

HDMI and official dsi screen at the same time? Pi2

Have dug out a Pi2 attached to the official dsi screen, and updated to the latest full version of raspbian. Power supply is adequate I believe. I have tried various combinations of legacy/fkms/FB from the raspi-config menu: at times the HDMI/DVI monitor works and shows the desktop, but mostly the 4p...

Re: Raspberry Pi High Quality Camera Launched !

A technical question: there's a drawing of the new camera board face-on with dimensions. I haven't seen a diagram with dimensions edge-on, showing the exact distance from the plane of the sensor to the back of the circuit board/tallest component. I'm thinking about the feasibility of using a HQ came...

Re: Exterior Gate Alarm, Horse Farm, Wireless

Just a suggestion, shoot me down in flames if it's not feasible, 😁; how about attaching something at the *hinge* end of the gates - rather than just open/closed, you could generate a signal proportional to the swing of the gates. Perhaps doing both, would show if gate was opened for human/horse/hors...

There's a guy somewhere on the forum asking if he should get his son a Pi for going to uni. He's going to need a key-ring, isn't he? Giving your son a bottle opener for the university may send the wrong message. I think an official Pi heatsink shaped into the Raspberry logo (along with a 3B+ to ins...

Re: GPS MODULE

The Adafruit Ultimate GPS (Hat or breakout board) also has a 1pps pin, which can be used to synchronise a NTP server, should you wish to build one.
Not required in all use cases, but useful if you want one.

I have used the Adafruit ultimate GPS breakout. The PPS signal is taken from the 1pps pin on the breakout board, and needs to be fed to a GPIO pin, and referenced in your code.

Re: Red Artifacts on Video from HDMI

I had something similar: HDMI to dvi lead into a TV/monitor, screen would occasionally flash red intermittently, wiggling it made it better/worse, until I replaced the cable.

Try some other HDMI cables & see if the problem goes away.
