I just tried this: char filbuff1[86410]; char filbuff2[86410]; void setup() { // put your setup code here, to run once: filbuff1[0]=0; filbuff2[0]=0; } void loop() { // put your main code here, to run repeatedly: } Which gives: region `dram0_0_seg' overflowed by 68512 bytes Which basically means not...

I just compiled this test: static char filbuff1[86410]; void setup() { // put your setup code here, to run once: filbuff1[0]=0; } void loop() { // put your main code here, to run repeatedly: } Which gives: Global variables use 10888 bytes (3%) of dynamic memory, leaving 284024 bytes for local variab...

If you declared them in a function, they are not counted as 'Global variables' but are 'Local variables'. Global declaration: char filbuff1[86410]; void setup() { // put your setup code here, to run once: filbuff1[0]=0; } void loop() { // put your main code here, to run repeatedly: } Gives: Global v...

and you still need a free pin to feed your sensors.

Yeah, you are right, what was I thinking when I made that post?
No idea...

You can have the sensors do their conversions one at a time

Yes, that is of course a possibility.

I did not mention that as it adds to code complexity and you still need a free pin to feed your sensors.

To be fair, there were some OneWire issues some time ago. I am using DS18B20 sensors for some of my projects for the last years and the issue mainly was that 'some' transactions went 'bad' as in the checksum was not valid. These transactions ( I had a rate of about 1 in 50 transactions going bad, de...

I recently stumbled upon this repo:
https://github.com/botofancalin/M5Stack ... cilloscope
Might find some info there.

A power supply problem? Are you using parasitic power? Feeding all that sensors from a ESP32 pin?
I use 3 DS18B20 sensors in a project, fed by dedicated power, and they keep running, well forever.

... then ALL sensors goes blank.

Blank means what exactly?

Thanks Neil! EDIT: These scripts work for Linux only. If anyone could port these scripts to Windows and/or OSX and post them in this thread it would be greatly appreciated. /EDIT I now got it working like I want it. The script has become 2 scripts. One for flashing, let's call that one flash.sh : ec...

After consulting a well known search engine I got this thrown together: rm version.h echo -n 'const char * sketchVersion "' > version.h git --no-pager describe --tags --always --dirty>>version.h echo -n '";' >> version.h which is basically what I want, but produces this output: const char * sketchVe...
