It is alway cool to solder up a modul, plug it in and see that it is working – ok half a modul. Had to use the old CAN Hub as I have not soldered up any of the new main boards yet. I urgently need the NMEA2000 interface as a friend have problems in…

Following up on my previous entry – I think the new header on sub-diagrams worked out well. Colors/background can be changed in preferences, but the symbol is very different from function call and it is square to make it easy to attach lines. I could have used the more classic UML Package, but that header…
UML State is in effect a sub-diagram and I need a few improvements on how I visualize sub-diagrams. Under is a classic example on how I would draw 2 diagrams with 8 events/methods that goes from diagram to diagram. While this is possible and sometimes wanted it is also a bit clumbersome. To improve…
One of the challenges is how to visualize ECU in BSA. The symbols below are highly exprimental and mostly added to drive the discussion about how to do this in a system diagram if you have an ECU with sub-modules. How do I visualize this in a diagram creating code for that ECU? The “PWM…
RL have a tendency to hit in with to much work sometimes reducing the amount of time I can use on these projects, but I finally decided to do a push on BSA again and complete print & copy functions. Below is some pictures – the first shows a mock-up diagram with all symbols on…
This first picture show an open box with Ethernet + 5 Add-On modules. Screw holes fit perfect, cables line up and it was a dream to assemble one box with full content. The mechanics of this project is a success. Cloed box with M12’s and MX23 sticking out below. I only need minor adjustments on…
The 3 x Analogue module below will get some siblings, The current module is experimental as I need to play around with analogue input a bit and see what I can achieve, The target is vibration sensors this time that is ok with 0-5V input. But, the module is so much more capable than this…
An old modul to the left and two new moduls to the right – I thought my old module was small… This is the first run on this series so the main issue right now is mechanical design + correcting bugs – don’t worry, I have found some already – mechanical ones, but that is…
A quick draft of a 8 Digital Input Channel module allowing 24V or 5V selectable per channel. I will receive the first batch of PCB’s tomorrow so fun will start, but I fancied having a look at a 8 channel digital input where I can select between 5V and 24V levels per channel.
With a main board and up to 8 sub-modules I need to design ipc communication between them. The sub-module uses a fast, exclusive serial port 1:1, but we also need to take into account Ethernet, RS485 and CAN as media. The essense of easyIPC is that I want a protocol where I don’t care about…
