With Model 5, the Raspberry Pi Foundation has also introduced an updated version of theRaspberry Pi OSdistribution. Although the desktop appears unchanged visually and in terms of operation, major changes have been made behind the scenes: Raspberry-Pi-OS now uses Debian 12 “Bookworm” as its b...
GPIO BCM (GPIO.BCM) is the Broadcom Soc Channel numbering. In the diagram above, you can find the number after GPIO. For example, on the Raspberry Pi 5, the pin below 3v3 is GPIO2, so the number for this pin is 2 in BCM mode. A downside to BCM is that they have changed between...
When searching for accessories for your Raspberry Pi 5, you really need to make sure that they are compatible. The GPIO may look the same, but some HATs no longer work and require a software workaround in order to be used. Confirm that the software for your chosen board will work before...
The access to USB bulk endpoints on the Raspberry Pi 1-3 in no-hub configurations was occupying the whole USB bandwidth, which was not allowing to access other endpoints on the same USB device. The I2C master was not initialized on the Raspberry Pi 5 insample/34-sounddevices. ...
For example GPIO3 and GPIO 4 are also SDA and SCL I2C pins used to connect devices using the I2C protocol. To use these pins with these protocols we need to enable the interfaces using the Raspberry Pi Configuration application found in the Raspbian OS, Preferences menu. I2C, SPI and UART...
