Pyboard D Series MicroPython Board Features STM32F7 MCU, WiFi and Bluetooth

Pyboard D Series

Micropython is a lightweight implementation of Python for microcontroller which we covered first in 2013. The port is supported by various hardware platforms, and I even tested Micropython on ESP32 a little while ago, but the developer – Damien George – also launched officially supported boards starting with Pyboard in 2014 with an STM32F4 microcontroller. At FOSDEM 2019, the upcoming Pyboard D-series (aka Pyboard D, or just PyBD) board was introduced during the Micropython presentation with a faster STM32F7 Cortex-M7 MCU, as well as built-in WiFi and Bluetooth connectivity. Pyboard D preliminary specifications: MCU – STMicro STM32F7xx Arm Cortex M7 microcontroller at 216 MHz with 512KB RAM, 2MB flash Storage – micro SD card slot, and 2x external flash chips Connectivity – WiFi & Bluetooth with on-board antenna and u.FL antenna connector USB – 1x micro USB port for power, flash disk access, and USB to serial debugging/programming Expansion 2.54mm pitch through holes for 16x GPIOs 1.27mm pitch castellated and …

FOSDEM 2019 Open Source Developers Meeting Schedule

FOSDEM 2019

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where developers meet on the first week-end of February to discuss open source software & hardware projects. FOSDEM 2019 will take place on February 2 & 3, and the schedule has already been published with 671 speakers scheduled to speak in 711 events themselves sorted in 62 tracks. Like every year, I’ll create a virtual schedule based on some of the sessions most relevant to this blog in tracks such as  open hardware, open media, RISC-V, and hardware enablement tracks. February 2 10:30 – 10:55 – VkRunner: a Vulkan shader test tool by Neil Roberts A presentation of VkRunner which is a tool to help test the compiler in your Vulkan driver using simple high-level scripts. Perhaps the largest part of developing a modern graphics driver revolves around getting the compiler to generate the correct code. In order to achieve this, extensive …
