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…
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…

LetsTrust TPM ist eine Aufsteck-Platine mit elektronischen Komponenten in den Abmessungen 12 mm x 15 mm x 5 mm. Sie ist zum Einsatz mit dem Raspberry Pi Einplatinencomputer vorgesehen. Die Hauptkomponente von LetsTrust TPM ist ein Kryptographie-Chip, der Infineon Optiga™ SLB 9670 TPM 2.0. Die anderen Komponenten auf LetsTrust TPM sind passive Komponenten, sowie eine…
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…
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…
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…
WeiterlesenPiCockpit v2.0 released – amazing new features!
Yesterday, on the 6th of October 2020, we have released the new version of PiCockpit – which has many new, exciting features. And best of all: PiCockpit continues to be free of charge (as in free beer), for up to 5 Raspberry Pis! Get started for free today. What is picockpit.com? PiCockpit is an easy…
WeiterlesenHow to bring up the camera and display on a compute module carrier board
We have developed our own Compute Module Carrier Board, called PCCB. It is compatible with Raspberry Pi Compute Modules 1 – 3 Plus, and has a number of very useful features for industrial use (RS232, CAN Bus, RS485, TPM, DC/DC Stepdown). Today, I verified the camera and 7’’ display interface which we provide on the…
