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…

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…

WeiterlesenVuetify :: Open detail row programmatically
For the upcoming PiCockpit v2.0 release, I am preparing a GPIO application. The GPIO entries are table rows – and to configure them, we want to be able to access the detail row by clicking on the configure button: clicking either the chevron or the configure button will lead to the detail row opening: Here…
Weiterlesenenabling and disabling a systemd service in Python using DBus
The upcoming picockpit-client reacts to deletion events from the frontend by disabling it’s service (the application will stay installed, however). Similarly, when you decide to run picockpit-client connect again, the service will be re-enabled and started automatically for you. This is possible using the Python DBus interface. the DBus is a bus system for interacting…
WeiterlesenRaspbian SSH Server fails after upgrade from Stretch to Buster (no SSH connection)
I used this excellent guide to update my Raspbian from Stretch to Buster: https://pimylifeup.com/upgrade-raspbian-stretch-to-raspbian-buster/ After rebooting my Pi, the SSH connection was gone. Logging into the Pi using the attached keyboard and monitor allowed me to debug the issue: service ssh status journalctl -u ssh -n 200 „Missing privilege separation directory /run/sshd“ This directory needs…
WeiterlesenHow to set unique object ids in embedded documents across a MongoDB collection
MongoDB’s updateMany can be used to update all documents which are matched. Problem If, however, you want to set unique new ObjectIDs in your update, you would find that MongoDB sets the same ObjectID for every entry: db.getCollection(‚mypis_collectedpis‘).updateMany({}, {$set: {apps: { „com.picockpit/core“: { meta: { version: „2.0“, name: „PiCockpit Core“, image: „“, description: „PiCockpit.com…
Weiterlesenswitching from JSON to MsgPack in a backwards compatible manner with Paho MQTT (JavaScript)
picockpit.com makes heavy use of MQTT. For the upcoming version 2.0 I have decided to switch it to MsgPack. Why MsgPack? MsgPack (actually called MessagePack – packages tend to use MsgPack) is a binary format, aimed at compatibility with JSON, but decreasing file size (which is good for saving bandwidth & server resources). Another advantage:…
