Modos Flow – An FPGA-based 13.3-inch USB-C touchscreen e-paper monitor (Crowdfunding)
Modos Flow is a paper-like, 13.3-inch USB Type-C touchscreen monochrome or color monitor that builds upon the Modos Paper devkit introduced last year with an AMD/Xilinx Spartan-6 LX16 FPGA and STMicro STM32H750 Arm Cortex-M7 microcontroller. The main difference is that the Modos Flow is more like a consumer product with a full enclosure, a touchscreen, and optional stylus support, 4096-color e-paper display, and frontlight. Modos Flow specifications: FPGA – AMD Xilinx Spartan-6 LX16 FPGA running Caster gateware like the earlier devkit MCU – STMicro STM32H750 Arm Cortex-M7 microcontroller for USB communication, firmware upgrades, and standalone applications. Display 13.3-inch e-paper display with 3200 x 2400 resolution Refresh rate - 60 Hz with additional power, 40 Hz via a single USB-C cable Monochrome or 4096 colors/16 levels of grayscale Touchscreen support Optimized display modes for reading, browsing, watching, and writing Amber-tinted frontlight (color model only) Video Input - USB Type-C DisplayPort Alt-Mode with
So I found one problem, there is a trace that shorts out this component. Very likely I moved a bunch of component after routing. *screms*
Tried cutting the trace on the board but it was still shorted. This is just one shorted component, a few other places were shorted as well, even on the boards with no components.
In any case I did up a new board that's slightly wider for more routing space and fixed up the footprint for the regulator.
Some thougts whilst working on the board:
- 0805 size is good for me to solder even without magnification.
- I tried drag soldering the mcu and got one pair of pins shorted, and I could not get rid of it, even using a wick.
- I cannot tell visually if the pins were shorted, I had to use my phone's camera, and even then it was _barely_ visible. Likely I will get one of those el-cheap usb microscopes to check.
- Using a penknife to cut through a pcb is zzzzz XD
Serial Terminal: кастомный веб-терминал для последовательного порта на Web Serial API
Полностью браузерный терминал для работы с последовательными портами (COM-портами). Приложение не требует установки, работает прямо в Chrome или Edge, и при этом поддерживает все необходимые фичи для отладки микроконтроллеров, общения с сетевым железом или просто мониторинга UART-трафика. https://github.com/GidroByte/web-serial-terminal-ru Весь код одним файлом. Не требует компиляции и сборки, леко править обычным блокнотом — открыл и работаешь.
Веб-терминал для последовательного порта (Web Serial API). Альтернатива PuTTY/minicom в браузере. Поддержка UART/RS-232: скорость, биты данных, чётность, стоп-биты. HEX-режим, таймстампы, автопрокр...
«Ща будет шрифт»: история одного русского embedded‑шрифта
Ни когда не думал, что программированием можно увлечься, но около года назад я узнал про существование микроконтроллеров и тут началось. Мне нужен шрифт, причём срочно! — Так я подумал спустя полгода. В сумбурном поиске я попробовал много вариантов, приводивших к систематическому разочарованию. Спустя еще пару месяцев этот вопрос начал тормозить моё обучение и вводить в депрессию.
A NEW way to use STM32CubeMX and STM32CubeIDE - STM32 Short #12
A side-effect (possibly unintentional) of ST splitting up STM32CubeMX and STM32CubeMX2 is that one can now use CMake files throughout - even when using STM32CubeIDE. This video will explain how.
This approach was not possible with the pre-2.0.0 version of STM32CubeIDE but it is actually much better than the old.
#STM32 #Tutorial #STM32CubeMX #STM32CubeIDE #CMake #STM32World
#embedded #stm32 #CortexM0 #arm #codium #podman
So I've got a pretty decent recipe now for creating a containerized embedded build environment for ARM Cortex devices using slop-free tooling like PodMan and Codium.
It's a bit more work than using VSCode and the built in devcontainer support, but I think it's still useable for a typical embedded developer.
It works on Windows and Linux and (I'm assuming) MacOS as well.
Is this something the community would be interested in reading about?
TITLE FIGHT STM32 vs. RP2350 - Who is the WINNER | RP Pico #2
In an earlier video we asked the question which MCU is best - STM32 or RP2350. We never really answered that question. In this video we will attempt just that ;) So buckle up and watch a battle between STM32F4, STM32C5 and RP2354.
