I recently made a Data Logger using a Nucleo-144 board and 16 bit ADC’s – the project works well and I am a bit surpriced over how easy it was to create both electronics, firmware and PC software, so I will attempt an even more advanced Data Logger illustrated below: A functional block diagram over…
Fork and Join are part of UML State diagram heritage that I imported into PLD. The example below show a potential usage to take a signal, duplicate it to three threads and wait until they all are finished before you continue. Fork and Join are drawn as bars that can be horisontal or vertical –…
One of my concerns on 600V design is how to make ADC readings in the 600V area. I need 3 x Current sensors, 1 x DC Voltage Sensor and 1(2) x Temperature sensors in addition to support for up to 3 resolver sensors as well as an external motor temperature sensor. That sums up to…
This MCU started to interest me because it is a low price alternative with a lot of contents. ST’s price is 1.7 USD, but that is 3++ USD through Digikey in low volume. It is a 128Kb Flash version, but it has a promissing build-in Bootloader that I want to experiment with. If you build…
Testing and fixing bugs are part of a normal development cycle. I created a diagram of BSA itself for testing and as it re-loaded it looked good. I then moved BSASymbol and got a shock as several of the lines was linked to an invisible ghost symbol. The original lines was from the save, but…
The “Main” or Central Computer if you like is basically a large MCU with 3 x CAN ports and 10 x Modul links. It only need a 5V PSU and can be used stand-alone or combined with other modules to form a larger entity. The central computer controls the entire system of both internal and…
I created the footprint for GX16-8 and updated the 3D with a few details. I will see if I can add the thread as well. I quite like these connectors, but I am a bit concerned that I only find them on one source on Aliexpress + I realized that these connectors have a different…
I will upload these packages on github (here) because it is 2 days wasted work having to draw them and I depend on others publishing their 3D packages myself. Just be aware that these are Beta – their accuracy is subject for testing. I will draw the last five as I get them. Have fun.…
I fancied using GX16 connectors in a project since they are low cost, robust and can be made water proof. I found 2,3,4,5,6,7,8,9,10 and 12 pin versions with bend pins so they can be mounted directly on a PCB and fixed to a panel. But, what I did not find was 3D models for KiCAD,…
I have lately had the priviledge of working with two vendors of mobile, electrical vehichles – one used a self-developed system designed for volume production series, the other was a larger industrial vehiche on prototy level where they started with a standard PLC and a small cabinet. Usage of a standard PLC “kind of works”,…
