Raspberry Pi single board computer market share of total PC market in 2020
For a report I’m preparing for a bank, today I’ve calculated the market share of the Raspberry Pi single board computers (all models) in the worldwide PC market in 2020. Here it is: 2,69 % (at 7.4 Million shipped Raspberry Pi units in 2020) Here is how I came up with this figure: Calculated the…
WeiterlesenTurn 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…
WeiterlesenWill the Raspberry Pi 400 be available in an 8GB version?
The Pi400 already has a lot of basic models due to the languages, which of course is a bigger logistic challenge for Raspberry Pi and its partners.The standard version of the Pi 400 with 4 GB covers most (consumer / school children / students) application purposes. 8 GB are rather needed in the area of…
WeiterlesenThe technology & security foundations of PiCockpit
I was asked to elaborate a bit about the security & technology foundations of PiCockpit. The parts which are involved PiCockpit consists of several parts: picockpit-client picockpit-frontend picockpit-backend picockpit-api (“papi”) the database the MQTT server the picockpit Package repository The MQTT server Data between the picockpit-frontend and picockpit-client is exchanged using the MQTT server (called…
WeiterlesenFlashing the PCCB Raspberry Pi Industrial Compute Module Carrier Board using a Windows computer
The PCCB is our Raspberry Pi Compute Module carrier board with industrial interfaces: I will describe how to flash the PCCB flash using a Windows Computer. Prerequisites USB power supply (or DC power supply) PCCB compute module with on-board flash (Raspberry Pi Compute Module Lite variants do not have Flash on board) microUSB to USB…
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…
WeiterlesenStress testing a Raspberry Pi 4 with PiCockpit – temperature monitoring
Using the new PiCockpit v2.0 release, you can monitor the current SoC temperature of the Pi in an easy to use webinterface (in PiStats). Simply click on PiStats, and enter temp into the search: this will narrow the display down to just the SoC temperature. The temperature will be updated every second. I also recommend…
