I finally got new PCB’s for this utility driver and I still can’t get the programmer port to work automatically. All engineering is like that some times – try and fail – two steps forward, one step back. In this case it sadly involves waiting 6+ weeks for a new PCB once I find ut…
I decided to change the Call Instruction to the one below. As we return with an event code we consume the NIX and process the first “On” that will test for event code and continue to next “On” if not. At this point I can consider dropping “On” and replace it with “If” or “Switch”…
All the Plain entries in here have served their design purpose as I consolidate and wrap up Plain Specification. I usually never bother with a specification on software I do at home, but the complexity and technical design of both language and VM have to many details that needs to be right. The new VM…
Josef Prusa recently launched 2 3D Printer upgrades that are worth noticing. One is the MK3 and the second is the new MMU Upgrade for the MK3. The total price of these will be something like 900.- EUR. I have copied pictures of them below: MK3 implement new technologies that are very interesting comparing with…
My first laser printer (a HP) stopper working after years of usage, and I have been in the marked for a color laser for some time. They had a Brother DCP9015CDP on sale, so I went for it. This is a large All-In-One printer with Wifi. It was dead easy to set up and my…
A blog is excellent for sharing ideas down and returning to evolve them later. It’s been a while since I wrote about Plain. I basically stopped because I had other things I wanted to work on, but I think it is time to review/consolidate the specification and move on. Is it worth it? Will it…
I have been in the marked for a CAD program for some time and finally realized that Autodesk Fusion 360 is free for non-commercial and minor commercial usage. It also have loads of training videos to get you started. I have only been using it for a day, but it seems to do the job.
#4 on the picture above is Servo channels. I discovered that only 8 of there are working as expected. The 4 last ones have GPIO 34-39 that failed in testing – and reading small notes in the datasheet I realize that I have missed out a “input only” note on these pins. And guess 3…
I have tried PlatformIO twice. Once for STM32 and now for ESP32. PlatformIO promote itself as open source, but it looks more like a commercial solution with version No 0.14. It can be added to Visual Studio Code. It imports existing Arduino Projects etc. But, well – two attempts and it is still sorted under…
Having used Arduino IDE to develope the ESP32 Utility Driver code I must admit that while I in general like Arduino I also miss a proper code editor. Sticking to Arduino (for now) I decided top try out Visual Studio Code. Visual Studio Code is basically a free and liteweight version of Visual Studio. In…
