Re: Switch to turn on and off the P4

I do it via a dtoverlay, dtoverlay=gpio-shutdown . Momentarily grounding GPIO 3 will have Raspbian / Pi OS do a proper shutdown. And by default, grounding that pin again will have it boot back up. As long as you don't unplug the power supply. Enabling i2c will stop the shutdown from working via GPIO...

Re: How do i change the time

IMHO adding a RTC is the way to go if you want accurate date and time on bootup. I have a couple of portable setups that there is no guarantee that they will be able to connect via WIFI. And they display the date and time, plus other info. Adding a RTC saves manually having to reset the date and tim...

Re: Thermal paste or pad for Argon One Pi4?

I'm with pidd, thermal past is great for close contact scenario's. With any kind of gap I'd be using a thermal pad, and one that is the same of close to the same thickness as what was in there originally.

Re: DS3231 problem on Rpi 3B

Ok, when you said "same problem all the time on the one not working" I thought you meant the DS3231, but you meant the Pi. I'm pretty sure there is a second alternate i2c bus that can be enabled, I have never done it, and don't know how its done though?

There is no ARM Windows for the Raspberry Pi. Is it possible to install windows on a raspberry pi. Not on a Pi 4 no. You can install Windows 10 Internet of Things on a Pi 3B but Windows 10 IoT isn't your standard Windows. It's a very basic and IMHO limited interface. And I think you'll need some Vi...

It likely has a short to ground on one of the i2c pins. It's for sure a hardware issue. If you have soldered a header on it double check the soldering.

Thanks for that. Weird thing is, I have been using it for over a year now, plug + play without having to do anything extra? It works right out of the box in Stretch or Jessie. If that driver will get it working I'll happily install it though.

Re: Raspberry Pi 4 White/Red Case Sufficient

I also really like that case, from a looks perspective. It's a nice quality case. But, unless something has changed, IMHO, it's lacking in ventilation. There are no vent holes to let hot air out. The Pi 4 will not overheat, but if it does get overly hot it will throttle back to keep from overheating...

Re: No red LED Pi 4B

I would think that if the voltage was so low that the LED didn't turn on, that the Pi wouldn't even boot up? Maybe the LED got flipped around backwards some how, and its reverse biased? The red LED turns off when the voltage falls below 4.63V, IIRC. This is well outside the specified minimum of 4.7...

Re: Raspberry Pi shows a colorful screen when booting raspberry pi os desktop

As mentioned, that's normal to see that screen flash up on boot up.
You can disable that if you don't want to see it.
You just edit the config.txt file

sudo nano /boot/config.txt

and add

disable_splash=1
