Conflict with OneWire?

[thelastoutpostworkshop]

Thank again it will help. I do not know yet when I will be able to test it, stay tuned!

Yes there is probably a conflict, I dot not have a DS18B20, but I will try to find a way to test it.
Can you try with version 1.5 of the GPIOViewer library to see if you get the same results ?

Hey hey, ok so I had success. The following versions had a compiler issue:

• 1.5.0
• 1.5.1
• 1.5.2
• 1.5.3

The error was:

In file included from /Users/myname/Documents/Arduino/sarel/sarel.ino:1:
/Users/myname/Documents/Arduino/libraries/GPIOViewer/src/gpio_viewer.h: In member function 'int GPIOViewer::readGPIO(int, uint32_t*, pinTypes*)':
/Users/myname/Documents/Arduino/libraries/GPIOViewer/src/gpio_viewer.h:500:33: error: 'analogGetChannel' was not declared in this scope; did you mean 'analogChannel'?
  500 |         uint8_t analogChannel = analogGetChannel(gpioNum);
      |                                 ^~~~~~~~~~~~~~~~
      |                                 analogChannel

exit status 1

Compilation error: exit status 1

When I tried 1.5.4 it compiled, and upon running it I got a good result:

GPIOViewer >> Connected to WiFi
GPIOViewer >> Release 1.5.4
GPIOViewer >> ESP32 Core Version 3.0.4
GPIOViewer >> Chip Model:ESP32-D0WDQ6, revision:100
GPIOViewer >> No PSRAM
GPIOViewer >> Web Application URL is: http://192.168.107.132:8080
19.00
19.06
19.00
19.06
19.06

Tried version 1.5.5 and that was fine too:

GPIOViewer >> Connected to WiFi
GPIOViewer >> Release 1.5.5
GPIOViewer >> ESP32 Core Version 3.0.4
GPIOViewer >> Chip Model:ESP32-D0WDQ6, revision:100
GPIOViewer >> No PSRAM
GPIOViewer >> Web Application URL is: http://192.168.107.132:8080
19.06
19.06
19.06

So it appears the bug is with 1.5.6 specifically.

ok thanks for doing the test, Do you see pin activity on your GPIO 33 (oneWireBus) in the GPIOViewer web application ?

[sarelvdwalt]

Any time :) Yes, I do see activity on it - but only after a while.

• v1.5.5 (where it's working fine) - I see activity immediately, and it's binary (so it shows "High" with a red circle)
• v1.5.6 (where it's broken) - after initial startup it doesn't show anything, and after a while (around a minute later at most) it shows Analog red, value 4095.
