Yes, all the DC negatives (grounds) should be tied. Optionally tie that to AC ground as well to possibly further reduce noise. Note that 'transformer'...
Yes, the software is the same. PT100 amps use SPI communications and the LCD uses I2C - these have different pins. I'm fairly confident this isn't a s...
Again, its really difficult to diagnose without a schematic and/or pictures. EMI is tricky to resolve... and there is no real way we can offer up much...
Sounds like it does. The ve are power, the signal is likely Active Low... meaning ground. Specifically, that would mean -ve to ground, +ve to +5V (not...
I don't think a opto-isolation is the problem. Without a schematic (and/or pictures) of how you have it wired, I really can't give you accurate direct...
It is likely a ground and/or noise isolation issue. Can you post up a schematic of how this is all wired?
Sorry... never saw this. I don't know why you would want to reset a microcontroller via itself. If it is working and communicating, it is working and ...
Sorry... the adafruit one isn't very costly... best to grab one of those.
It looks like it could work, but I see a different chip than the one on the Adafruit LCD backback, so I cannot day for certain. You could try it, or s...
Actually, we didn’t publish a specific FW for the NodeMCU. There are a lot of ESP8266/85 variants which makes it tricky to support. When we finalize ...
That's cool! I appreciate your efforts extending the software! That said... maybe don't put too much more work in. I think we have something imminent ...
Hi BC Users, We posted v1.1 Release Candidate (build v1.0.1.14). Updates in this build:1. Added a Primary Value setting for Counter, Hydrometer, and P...
I'm not sure why anyone would write a script line setting the background to a value higher than 3? We would rather not stop a running script unless it...
I understand... Not sure how to solve this... would we just make the one side dynamic?
