The Teensy boards are especially popular among hobbyists, thanks to their high performance and compact size.

Here is the procedure to connect the Teensy 3 to the Pervasive Diplays EXT3.

One of the most critical challenge of embedded systems is managing the power budget. And very often, measuring power consumption turns into another major challenge.

Nordic comes with an interesting option: a universal ammeter with 8 logic inputs, with a dedicated application running on Linux, Mac and Windows.

How to display pictures on a remote screen?

This project uses the open-source MQTT protocol. To save bandwidth, the pictures are first compressed on a local PC. An ESP32 board receives and displays the images on the e-paper panel.

The transition from macOS to Linux, and from Xcode to Visual Studio Code, was easier than expected.

Although the offer of modern IDEs is rich, with PlatformIO and the new Arduino IDE 2.0, I am still missing some features and flexibility.

Porting embedXcode to the new environment required virtually no changes, except some minor adaptations of paths ​

embedXcode is now emCode.

emCode runs seamlessly on Linux and Windows with Windows Subsystem for Linux (WSL). It leverages the built-in debugger of Visual Studio Code and remote development for WSL.

I haven't decided yet to share emCode as I did for embedXcode.

How to build a low-power weather station with off-the-shelf components?

• The Pervasive Displays E-Paper Display Pico Kit (or EPDK) brings the controller board and the e-paper display. This technology only requires power to change the display and keeps the display unchanged even when powered-off.
• A Bosch BME680 sensor measures temperature, relative humidity, barometric pressure and gas, actually a level of volatile organic compounds (or VOC).
• Dedicated libraries based on the Arduino SDK drive the screen and the sensor.

How to start exploring e-paper technology?

The Pervasive Displays E-Paper Display Pico Kit (or EPDK) provides everything to start with. The kit includes a 2.66" screen, an e-Paper EPD Extension Kit Gen 3, a 20-way cable and a Raspberry Pi Pico RP2040. Library, documentation and examples are available online.

The boards based on the Espressif ESP32 are very popular. Here is the procedure to connect the ESP32-DevKitC to the Pervasive Diplasy EXT3.

Thank you to W. Shepherd Pitts and Joe Harrison from NCSU for the idea.

One of the major complain about e-paper screen is the slow update.

Here is an interesting solution from Pervasive Displays: a new version of the 2.71" e-paper screen with embedded fast update.

How faster does it perform? Read the full test.

Porting embedXcode to the new environment was very easy with virtually no changes. Only the paths needed to be adapted. ​
