Let’s start with that I’ve never – ever – soldered anything before. Although we define this pcb-build as beyond Arduino, I felt hopeful I could pull this off because of the excellent equipment in the lab and the guidance of @Blok2009. In the end it took me about 2,5 hours Read more
Another day at the market looking for parts. Happy hunting with a long list of things to get. The ground floor of one of the buildings used to be a beautiful mosaic, but it got smashed and broken by the amount of commerce taking place on top of it. Negotiating Read more
Huaqiangbei – to some of our group it already feels like smelling something from your childhood, to others it is a new shock to the circuit. After much browsing in the overload of little stalls with parts, knick-knacks and anything that can possibly be connected, the first actual purchase was a Read more
We were excited to see CITE and had ourselves an early start. We had some wonderful Chinese bread for breakfast – with the undetermined pork or fish sugary floss – and set out in the foggy morning. The big trade-show hall is within walking distance of our temporary home. When the Read more
Since the last post I spent quite some time with my new tool to dump sequences from my commercial debugger. After comparing these dumps to various codebases I found online (libswd, cmsis-dap, mchck) and comparing them to the various manuals on the subject, I managed to extract the command sets Read more
One of the great breakthroughs of the Arduino has been that to get started, you only need the device itself and the software. The try/fail/try again cycle of development got reduced to altering your code and pressing run (again). Most other platforms completely fail in this respect. Many chip-manufacturers have excellent Read more
by Krzysztof Foltman After the initial success with LPC810, I was ready to work on something with more memory and more I/O. Searching the Farnell catalogue for simple, low-cost and hobbyist-friendly MCUs, I found the tiny STM32F030F4P6 microcontroller made by ST Microelectronics. The microcontroller The chip is based on an Read more
by Krzysztof Foltman This is my first successful attempt to do something with a 32-bit microprocessor in a circuit of my own making, instead of relying on commercially-available development boards. After some prior unsuccessful tries using STM32F051 and TQFP64 to DIP breakout boards, I decided to start over with something easier. Something that Read more
Lauri just did some in-depth testing of MIDI roundtrip latency on USB devices! On USB latency Every so often someone mentions the dreaded USB latency. MIDI is MIDI, and USB is USB, do we need to mix both, and can that work reliably? Read all about it HERE!
I’ve had some great fun with the microgameboy from the Yellow Panel. See here: Adding levels with a custom level editor: And.. because you sortof have to… I made a small midi-file converter and attached a piezo beeper to a leftover GPIO pin… Initially I had some trouble getting Read more
