Re: Pi 4 Installation Issues

With its new BOOTROM (EEPROM) regular flashing of the green ACT LED will occur if the RPI doesn't detect start.elf, so only if the ACT LED flashes in an irregular pattern, the PI is booting! you can check this by removing the SD-card (and all other potential boot media) and turn the PI on, the ACT L...

Re: STICKY: Is your Pi not booting? (The Boot Problems Sticky)

This information is written especially for the RPI 4B . Unlike previous Raspberry PI's the RPI4B boots with the use of code from a built in EEPROM, that means it can use more complex boot code with more flexibility, and the ability to add new features. consequently when the new bootcode doesn't det...

Re: Help choosing a proper display for emulation.

For best performance you should use a display that doesn't need its own RPI driver, that is either HDMI or use the official 7" LCD. If you use a small display that uses an SPI interface you need a "framebuffer driver", that constantly copies the framebuffer (video RAM) to the display using a serial ...

Raspbian Is 32-BIT so its compatible with previous PI's.

If you MUST have a 64-bit OS (although its slower, and uses more memory) use another OS, there are several that support 64-bit

Thats not a QR code, QR codes are easily recognizable by the three alignment squares in three corners of the square.
not every two dimensional barcodes are QR (Quick Recognition) codes.

That would work, but if you program the GPIO as an output, and the switch is closed a large current would flow, which destroys your PI, so I would also add a 330 Ohm resistor in series with the GPIO, like this. button_schem.png also again, the voltage the switch is connected to MUST BE 3V3, as show ...
