Re: RaspiWiFi - Headless wireless configuration for embedded

I do not get RaspiWifi running on my pi.

Re: RaspiWiFi - Headless wireless configuration for embedded

Great idea, 1+ for this project. I was looking for something like this. I found this project on github. It also provides a web interface to configure the wifi settings headless: https://github.com/marko8904/raspberry-wifi-conf.git It is not running stable, so I am looking for an alternative. I will ...

Glad that my pi is back to normal :-)

Restore PI3 to factory settings w/o Resin.io

I have successfully installed a resin.io image on my pi3. https://resin.io Now I can't boot the PI with a normal Rasbian image anymore. I realized that I do not need Resin.io and I just want to get back to normal again. The problem is that the pi doesn't boot anymore with a normal rasbian image and ...

Re: Backlight Control on Waveshare 5" Touchscreen

I didn't found anything that could suggest the backlight can be controlled. Looking at those low-res photos I can only tell that BL circuit is made on PT4103 (this circuit looks identical). I don't see anywhere any mentions about BL control nor there is no solder pad (or goldpin) to connect to free...

Saper_2 many thanks for giving your opinion :-) Very much appreciated! Thanks for your help. I also think that the way how you are controlling the backlight of your display is more an upgrade than a hack. Hacking sounds forbidden and your solution is not illegal ... so lets call it an upgrade ;-) I ...

I don't see a reason why the touch function shouldn´t work anymore. Just to make sure, is the touch screen still working, after you have hacked it?

Re: Backlight Control on Waveshare 5" Touchscreen

Ok, if it´s only possible to reset the usb ports and if the usb ports are permanently powered, it won't be easy to find a way to control the backlight of the waveshare 5" HDMI display by software. :(

Re: Backlight Control on Waveshare 5" Touchscreen

I just had the idea to set max_usb_current = 1 in /boot/config.txt to make the PI supply as much power as possible to the USB port. Then it might be possible to power the display via USB. I am not a 100% sure if the 1.2 A current that can be drawn from the power rail of the pi are sufficient to powe...

Maybe a problem with your power source? Christian, it was a problem with the power source. My 7" display was powered via the GPIO pins of my PI2.
