FOSDEM 2023 schedule – Open-source Embedded, Mobile, IoT, Arm, RISC-V, etc… projects

After two years of taking place exclusively online, FOSDEM 2023 is back in Brussels, Belgium with thousands expected to attend the 2023 version of the “Free and Open Source Developers’ European Meeting” both onsite and online. FOSDEM 2023 will take place on February 4-5 with 776 speakers, 762 events, and 63 tracks. As usual, I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Open Media”, “FOSS Educational Programming Languages devroom”, “RISC-V”, and others. FOSDEM Day 1 – Saturday February 4, 2023 10:30 – 10:55 – GStreamer State of the Union 2023 by Olivier Crête GStreamer is a popular multimedia framework making it possible to create a large variety of applications dealing with audio and video. Since the last FOSDEM, it has received a lot of new features: its RTP & WebRTC stack has greatly improved, Rust […]

Raspberry Pi Pico W to get Bluetooth LE support very soon

The Raspberry Pi Pico W board was launched with a WiFi 4 and Bluetooth 5.2 LE module based on the Infineon CYW43439 wireless chip in June 2022, and I wrote a tutorial showing how to connect to WiFi a few days after the launch, but nothing about Bluetooth LE. That’s because while the Raspberry Pi Pico W hardware supports Bluetooth LE, we were told that Bluetooth was not enabled at the time, but might be at a later stage. The good news comes from Alasdair Allan, who is responsible for the Raspberry Pi documentation, saying Bluetooth LE support is scheduled for the upcoming 1.5.0 release of the Pico C SDK. There’s currently an open ticket on GitHub for Bluetooth support added to the 1.5.0 milestone. At the time of writing, there are 14 open issues for the 1.5.0 milestone with no due date, but Alistair expects to see support publically […]

Bouffalo Lab BL616/BL618 RISC-V MCU supports WiFi 6, Bluetooth 5.2, and Zigbee

Bouffalo Lab BL616/BL618 is a 32-bit RISC-V wireless microcontroller with support for 2.4 GHz WiFi 6, Bluetooth 5.2 dual-mode, and an 802.15.4 radio for Zigbee, Thread, and Matter designed for IoT applications. We first spotted the BL616 RISC-V IoT MCU during the BL602/BL606 announcement in November 2020, but we had virtually no additional information about it so far. It appears both BL616 and BL618 will be launched next month with the main difference between the two being that BL616 has 19 GPIOs and BL618 comes with 35 GPIOs. Bouffalo Lab BL616 and BL618 specifications: MCU core – 32-bit RISC-V CPU (RV32IMAFCP) @ up to 320 MHz with FPU and DSP, 32KB instruction cache & 16KB data cache VPU – MJPEG video encoder Memory – 480KB SRAM, 4KB HBN RAM, embedded 4 or 8MB pSRAM (optional) Storage – 128KB ROM, 4Kb eFuse, embedded 2, 4, or 8MB flash (optional), XIP QSPI […]

Merlot is an open-source hardware tricolor wireless E-paper display

paperd.ink Merlot is a tricolor E-paper display with an open-source hardware control board based on ESP32 wireless SoC that is programmable with Arduino, MicroPython, or the ESP-IDF framework. We first wrote about the paperd.ink 4.2-inch ESP32-based monochrome e-Paper display last year, but the company has now refined its design with the “paperd.ink Classic” replacing the 3D printed enclosure with a vacuum cast enclosure and adding a 1,900 mAh battery. They also launched a new model, the Merlot, based on the same design but with a display supporting three colors: black, white, and red. Merlot specifications: Wireless module – ESP32-WROOM-32 module with ESP32 dual-core processor, 4 MB SPI flash, 2.4 GHz WiFi 4 & Bluetooth LE connectivity Storage – MicroSD card slot for storing images, files, etc Display – 4.2″ tricolor e-Paper display with 400 x 300 resolution; full refresh: ~ 17 seconds; partial update: also 17 seconds… USB – 1x […]

Pinecil V2 Bluetooth LE soldering iron gets a web interface

It’s now possible to make use of the Pinecil V2 soldering iron‘s Bluetooth LE connectivity through a web-based interface used to monitor and/or set the temperature and power of the RISC-V soldering iron. When the Pinecil V2 soldering iron was launched with a Bouffalo Lab BL706 RISC-V Bluetooth microcontroller last summer, we were told there were main potential cases to make use of the Bluetooth LE features: OTA firmware upgrade and remote telemetry and control. The latter is now being taken care of by Joric who has written a web application to visualize telemetry data and even control the temperature of the soldering iron. To be able to use the Bluetooth features, you’ll first need to install the latest Pinecil V2 firmware with blisp flashing utility before going to https://joric.github.io/pinecil to pair your soldering iron as explained in the wiki. Note the implementation relies on the Web Bluetooth API which […]
