Hello for everyone! Another year - another HackadayPrize. And we love it! And of course, for participate in the contest, you need to create new project page. In this year I enter to the contest with side project from my main big work - #Rhoby.The Social...
Aiming to improve in embedded firmware, electrical engineering, and software design. --- Features -------------------------------------------------------------- Makefile + SWD GDB upload and debugFreeRTOSBSP is essentially cores/teensy3Dispatch...
New release v0.11 is now available! The major change in this release is that I reworked the whole adapter so that the second core does not run FreeRTOS anymore. So it's essentially bare metal. That was a lot of work and I will make a separate log...
ProblemWith the rising rates of Covid patients in many countries with the removal of lockdown and people returning to normal lives it is necessary to prevent contact to public interfaces like machines or touch panels, doors etc as much as possible.There...
I'm a couple months into this already, so I've already tried and discarded a dozen ideas. Right now, I have an STM32F746 dev board driving the Sharp LCD at speeds up to 60FPS (finally), though I'm dropping that to 30-40FPS for practical usage. ...
Summary Time to Rise and Resurrect work on this project after languishing a few months. When I left off, I was having a Devil of a time getting eLua to work with absolute stability on my NetDuino/STM32Workbench/FreeRTOS platform. I am taking...
Hardware Block SchemaHardware is built around the STM32F103 microcontroller. CPU timing is derived from an 8MHz crystal; it provides a clock stable enough for an on-chip USB interface to function correctly. An auxiliary low-speed precision 32.768kHz...
Hello !I can imagine it's been a while since I last wrote, but I'll try to make it up in this entry.Since last time I've made some major changes. I decided to use ILI9320 lcd ( whichis at my place, and soon 'll be tested), also I'll buy an 2,2" touch...
Summary: I am trying to replace the malloc() implementation so as to get an idea of memory usage patterns. Along the way, I discovered some interesting things about the internals of libc, eLua, FreeRTOS, and some features of the linker. Deets:...
ESP32 development is done using ESP-IDF (Espressif IoT Development Framework) which is official framework. But nice people also created Arduino framework for it which makes this really easy for anyone familiar with Arduino. The standard Arduino IDE is...
Most makers working with the ESP32 can easily accomplish their goals by using the ESP-IDF integration with the Arduino IDE. With my background in hardware and low-level software, I wanted to learn a bit more about the ESP32 and went with the ESP IDF...
The keyboard is attached via SPI, clocked at 8MHz. Pi Pico is SPI slave. Unlike most emulators that connect a PS/2 or USB keyboard, the keyboard matrix is scanned by the actual software. So each OUT to the column select port is sent over to the...
It is aimed to run OPC UA server on ESP32 board (xtensa toolchain). The information model is handled under models.c/h file. It contains a temperature sensor(DHT22) read port 4, a callback method to call ESP32-WROOM on board LED and 2 relays, which can...
OK, now for code demolition! I work at a local public-access TV facility. I've been there since it opened, and I have overseen three major renovations of our technical spaces (and will see a fourth renovation, after the pandemic!) We...
