Hi
Sorry for the late reply - I don’t have enough time lately. I think I have too much passion, hobbies, interesting things to do. Besides, work, family, and it’s winter and I like skiing …
Regarding the DIY module - well, I made a dedicated PCB, assembled it, well … it works,
looks like this:
I added an emergency button function in the software. I am currently testing a DS18B20 digital temperature sensor with 1-wire interface, LCD display, small buzzer, etc. I have some ideas for their functionality but it’s just more fun than any real need.
A soon I’ll prepare a short movie where you can see the details better and I will share
all necessary files to make such device.
By the way, I was a bit surprised because I ordered a 4 pin cable from Snapmaker. I cut it in half to connect it to my module. But I saw that this is probably somehow different (maybe new) version.
The longest pin is GND and it is connected to the black wire. It makes sense, of course.
But it is the opposite of the cable cut by other users from this forum (e.g. Streupfeffer.)
P.S.
By the way, I am preparing a description /guide on CAN communication in Snapmaker 2.0, which includes examples, message identifiers, my program code fragments, etc.
It is 80% ready - I want to supplement it with examples and log files from CAN Bus Sniffer
to make everything better understandable. In a few days it will be ready.
