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.txt dtoverlay=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…
WeiterlesenRaspberry 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…
WeiterlesenLite version of PCCB
The PCCB is a carrier board for the Raspberry Pi Compute Module 1 – 3 B+. We are able to remove any parts of the full PCCB you do not need, thereby cutting your BOM cost & time to market significantly: For this particular customers only the following features remained: 10 / 100 Mbit/s LAN…
WeiterlesenControlling 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…

WeiterlesenGmail Workspace / Gmail Suite send e-Mail from server using msmtp
We are in the process of migrating to Gmail, to be able to delegate managing a mail server. We used ssmtp on our server to email mails before, using our own mail server (Zimbra). I have now managed to get Gmail Workspace working, and would like to share some pointers on how to do that.…
WeiterlesenUpdate picockpit-client for compatibility with v2.0
The new PiCockpit release has many new features, which require a new picockpit-client version (at least v2.0.1) for compatibility. What do you get by upgrading the picockpit-client / using PiCockpit v2.0? GPIO: control GPIO pins (input / output / software PWM to dim LEDs for example) PiControl: run commands on your Pi from the webinterface…
