Arduino handheld programmable controller - article in EdW 06/2022

This year I've decided that not only I will finish arduino handheld programmable controler project but I will also write an article describing it in detail. And I did. You can read about it in polish magazine "Elektronika dla Wszystkich" released in June 2022 (picture below). Also check this link. I know that this article may not be accesible to every person on the planet. Nevertheless I'm happy that it was interesting enough to be released to a bigger autience. If you wanna know how this device works I also recorded short video available below.

ArduSTL - arduino handheld programmer

Recently I've made this setup (in the picture). It's arduino nano connected to OLED display and 5 buttons. Basically what it does is you can program this device without connecting it to computer. You can just select instructions (statements) that will be executed one after another. This statements are simple assembler like instructions. Language is based on STL or SL - statement list (it is used in Siemens PLC's).  It's my new idea so as of now code is in mess and there is no documentation. It's a work in progress.

 

AT90USB162 Arduino Programmer

Recently I came up with an idea to make my own arduino programmer using the same board I used to make USB MIDI controler. As you can see on the pictures below board had some design flaws that I found this week but I managed to lunch it successfully. As in the previous case I've used LUFA's (Lightweight USB Framework for AVRs, formerly known as MyUSB) slightly modified USB Serial example. I'm going to use this circuit as AVR Node programmer and front panel controller.
