Turn off the Adafruit Capacitive Touch PiTFT Plus Display (#2423) on power-off

Using a device tree overlay it is easy to turn off the Adafruit display backlight once the Pi goes into power-off state.Simply add the following line to the end of /boot/config.txtdtoverlay=gpio-poweroff,gpiopin=18,active_low="y"This will drive this particular pin #18 (which is responsible for the backlight on the Adafruit PiTFT display) low on shutdown, and will keep it [...]

Raspberry Pi Compute Module 4 vs Compute Module 3

Raspberry Pi launched Compute Module 4, as a successor to Compute Module 3B+. The Compute Module 4 (CM4) is a so-called System on Module (SoM), which contains core parts which make up a Raspberry Pi 4, for example, and in addition to that eMMC Flash in different sizes (ranging from none for the Lite module [...]

Controlling LEDs on Alpine Linux using the command line

We have developed an embedded Raspberry Pi Compute Module carrier board for industrial use: the PCCB.As you can see, there are three (directly) user programmable LEDs on the PCCB: USER / INFO / ACT.These are defined in the device tree. For example, we can define the following in our device tree overlay://LEDs fragment@11 {   target [...]
