@denman0000_gitlab You can have a local json library stored on spiffs or embedded. It doesn't have to be remotely accessed.

@moose4621 ...Thank you soo much and ditto .. also happy to help you
@moose4621 ..you need sleep my friend .. make sure you get it
@moose4621 will catch up when you're well rested .. :)_

@denman0000_gitlab Reading the arduinojson library, looks to me like just what you need.

@ashthespy
@moose4621 -- did you crack the array?, @denman0000_gitlab evening!
Chris Dalby
@moose4621
@denman0000_gitlab Ha ha thanks, early morning hereand is me most productive in the 'puter.
@ashthespy Yes thanks Ash. I have a working version. But.... I was wondering why I now see what appears to be 4 arrays in the console. Or is it one array being read 4 ways?
Ash
@ashthespy
depends on how you are dumping it out in the console!
Chris Dalby
@moose4621
@ashthespy connection.onmessage = function (e) { console.log('Server: ', e.data);
Ash
@ashthespy
What happened to the typed arrays? ;-)
Chris Dalby
@moose4621
@ashthespy
if(event.data instanceof ArrayBuffer ){ var buffer = new Uint8Array(event.data);
@ashthespy @denman0000_gitlab Off to work again. :-(
Ash
@ashthespy
print out buffer and not e.data :-)

@moose4621 yes seems so re JSON ...
I read somewhere its a good idea to rather create static tables than dynamic ones
can anyone confirm ?
@ashthespy Howdy Ash .. hope all's well with you :-)

@skorokithakis yassu re tikanis ?
hi all has anyone played around with measuring dc voltages with ESP ? was just wondering what resistor sizes to use .. read somewhere that the ESP pin is 1,0 v max ?
den har
@denman0000_gitlab
This is what I was reading as a start

@moose4621 @ashthespy I found the problem that was confusing me .. turns out I was reading the wrong filename fromspiffs for my .js aaargh LOL go figure...So I have my string coming through in the payload and printf shows the line as I need and want it : value,value,value, etc. Now I just need to know how to save the payload data as a line in SPIFFS ... I currently can write or append to a file on spiffs but can't get the Variable type correct :-(

haha, hi @denman0000_gitlab
has anyone played around with small servos? why do they jitter so much when i try to drive them from the ESP?
den har
@denman0000_gitlab
@skorokithakis Hi .. sorry man I can't help there .. but maybe too much current drain ? maybe not sustained current ?
@skorokithakis Just a thought
Stavros Korokithakis
@skorokithakis
I don't think so, it just jitters while sitting there
thanks though
den har
@denman0000_gitlab
maybe its noise ? Perhaps feedback ? try pop a low drop diode into feed for servo ?
maybe a snubber circuit needed ?
I have in the past found that as an issue when driving mechanical relays ( they have a coli too) inductive load
Stavros Korokithakis
@skorokithakis
hmmm yes, i think it might be noise
i'll try mitigating that, thanks
den har
@denman0000_gitlab
saw this which might be an issue
esp8266/Arduino#4296
Stavros Korokithakis
@skorokithakis
that seems to be for a stepper
den har
@denman0000_gitlab
Try check the noise with a scope or drive from 12V (or other) battery
Stavros Korokithakis
@skorokithakis
I think I figured it out, because it's software PWM, the noise is crazy when you're connected to wiofi
wifi*
i'll try the ESP32, it might work better
den har
@denman0000_gitlab
Sorry Stavros .. got my wires crossed haha
Stavros Korokithakis
@skorokithakis
no problem man
den har
@denman0000_gitlab
wont caps and/or inductor help with that
Stavros Korokithakis
@skorokithakis
caps on the signal line?
or do you mean on the ESP power rail?
i think the timings are off because of the interrupts
