For Wednesday 6/29: Face to Face COMMUNITY PROJECT MEETING (click here)

TriEmbed Community Project ESP32C3+Dialog Mixed Signal FPGA
ESP32C3+Dialog Mixed Signal FPGA DIP or SMD adapter board

On Wednesday, 6/29/22 at 6:30pm at the Forge Initiative, 2172 N Salem St Suite 001, Apex, NC 27523 there will be another meeting of the TriEmbed comunity project to create and use development tools coupling ESP32 microcontrollers with Dialog mixed signal Field Programmable Gate Arrays (FPGAs).

Best to park on the street or in front of an adjacent building if possible so that folks who find the hill hard to walk can park in front of the door.

This will follow up from last month’s “installathon” format to refine tool chain installation and get as many people as possible up and running while turning attention to the Dialog Synthesis tool and creating and running some simple FPGA applications. There will also be demos of things around the corner and related technology (Aaardvark has a graphing function now!) A lot of work has gone into the project (special thanks to alpha testers Jaime Johnsen, Rob Mackie and Dawn Trembath and note taker Glen Smith). Bring your laptop (currently best support is for Linux followed by Windows Subsystem for Linux (WSL) but raw Windows will succeed with extra work and Docker images are in the works to take the sweat out. An ESP32 dev board is highly desirable but there will be a few spares at the meeting. The meeting will be facilitated by the usual suspects Rob Mackie, Nick Edgington and Pete Soper and is scheduled to end at 9pm.

The daily infection rate in Wake county is currently 433 per day and there will be high risk people at the meeting. Please wear a mask (available at the meeting). There will be an ice chest with some soft drinks to enjoy outside but you’re invited to bring your favorite.

FOR DECEMBER 13: Nick’s mixed signal fpga board AND COMMUNITY BOARD PROJECT STATUS

The normal meeting format will be followed (welcome new attendees, announcements, problem/design review of the month, presentation, community project status, show and tell). This month’s presentation will be by Nick Edgington of Edgington Labs. Nick will share details of a very inexpensive line of mixed signal FPGAs (initial breakout board coming from OSH Park). Additional meeting time will be devoted to the status of the TriEmbed Community “Espressif 32 bit processor board + FPGA(s)” development board project.

MARCH MEETING: PYTHON MODULES & LTE HAT for PI ZERO

We will meet via Jitsi at 7pm on Monday, March 8th. Jitsi works best with the Firefox web browser.

The online meeting URL is in a recent posting available in the email archive on this page .

Agenda:

– Welcome

– Announcements

– P.O.T.M. (Problem of the Month)

– CROTM (Code Review of the Month)

                Modules for Python – Carl Nobile

– Show and tell (open to all to share with the group)

Paul will show an LTE HAT for Pi Zero talking to the Internet in a remote setting

Raspberry PI becomes a brand

With the introduction of the Raspberry Pi Pico , “Raspberry Pi” can now be thought of as a brand with two distinct product types. The Pico board features a Foundation-designed chip on a small board only needing header pins, offering an inexpensive but very powerful and versatile microcontroller suited for applications where Linux is less well suited.

With two M0+ Cortex cores, six independent banks of SRAM totaling 254KB, support for execute in place (XIP) from up to 16MB of outboard flash (2MB on the Pico board) at up to 133MHz, and support for variable clock rate and novel programmable I/O control, this is not your everyday low-end Cortex board. Below is a list of links to more details about Pico, its processor chip, firmware, software and tool chain, as well as the complete collection of related source repositories. (1/26/2021: Some host platform-specific tools are also included now. Thanks, Mike Fulbright!).
