GPIO viewer does not work

[Marcelverhoeven]

I installed the latest release of GPOI viewer (1,0,3) I installed https://github.com/me-no-dev/ESPAsyncWebServer I entered in the gpioviewer.ino (= example code) my SSID and Pass I have added code: In the setup: pinMode(4, OUTPUT); and digitalWrite(4, LOW); In the loop: digitalWrite(4, HIGH); delay(1000); digitalWrite(4, LOW); delay(1000);

The Led connected to GPIO is flashing as expected at the rate of 1 sec, I also restated Arduino,

On my browser I see the Picture of the ESP DevKit v1 but ALL pins remain at "0" What might be the issue???

What view are you using in the web application ?

[Marcelverhoeven]

I also tried several other views and port 8080 and 5555

still the same issue

[thelastoutpostworkshop]

if you refresh your browser, you should see a message on the Serial monitor indicating that the ESP32 is connected to the web application :

I also tried port 8080 and 5555

[Marcelverhoeven]

Note: Free heap and Free Sketch are alive

But no GPIO info

[thelastoutpostworkshop]

Try clearing your browser cache data. Also, do you see the value of free heap changing ?

[Marcelverhoeven]

Try clearing your browser cache data ==> DONE Also, do you see the value of free heap changing ==> YES No solution,

that is strange, have you the latest version of Espressif boars :

I was experiencing the same problem but got it to work. I had to downgrade the board from version 2.0.14 to 2.0.11 and recompile.

[thelastoutpostworkshop]

Thanks for you help @wazzaguy, I am going to do some test with version 2.0.14

[thelastoutpostworkshop]

Just tested the library against Espressif Esp32 boards v.2.0.14 (latest version) and everything is working

[wazzaguy]

I updated from 2.0.11 to 2.0.14 and its not working again. @Marcelverhoeven does downgrading to 2.0.11 work for you?

@thelastoutpostworkshop which Board Manager URL are you using? I'm using https://espressif.github.io/arduino-esp32/package_esp32_index.json

[thelastoutpostworkshop]

@wazzaguy I have used the boards manager in the Arduino IDE 2 :

This is the library : https://github.com/espressif/arduino-esp32

This Worked for me as well. The Board version is the Problem 2.0.11 works fine. BTW, great tool. Thx.

I also encountered the same problem, web server, development board images, IO not working, always in 0. [ VSCODE PLATFORM]

#include <gpio_viewer.h> GPIOViewer gpio_viewer; void setup() { gpio_viewer.setSamplingInterval(50); gpio_viewer.connectToWifi("KM-Electronic(2.4G)", "00000000"); gpio_viewer.begin(); pinMode(16, OUTPUT); } void loop() { digitalWrite(16,!digitalRead(16)); vTaskDelay(1000); }

I had the same issue. I rolled back to 2.0.11 and it works.

[thelastoutpostworkshop]

I am kind of thinking that the reinstallation of the ESP32 boards solve the problem, if someone could try to go back to 2.0.14 to test it again please.

I updated to 2.0.14 and it was no longer working. I have reverted to 2.0.11 and it is now showing something again. I have noticed, however, that there seems to be a lot of activity for a very basic program. All I am doing at the moment is flashing a single LED, but 14 other pins are randomly switching state.

[thelastoutpostworkshop]

Thanks for trying it, I will have to investigate further. As for the activities, this could be "floating pins", the library reads the actual value of the pins

Same "issue" for me. 2.0.14 not working with s2 mini board. Reverting to 2.0.11 gets it going, but there is a lot of activity on non-used pins and after about 20-30 seconds the board resets and it takes some time to get back up. This pattern repeats itself.

I also run a simple blink program and use the LOLIN S2 Mini

GPIOViewer gpio_viewer;
#define LED_GPIO 1

void setup()
{
  Serial.begin(115200);
  gpio_viewer.connectToWifi("removed", "removed");
  pinMode(LED_GPIO, OUTPUT);
  gpio_viewer.begin();
}

void loop() {
  digitalWrite(LED_GPIO, HIGH);
  delay(1000);
  digitalWrite(LED_GPIO, LOW);
  delay(1000);  
}

[Marcelverhoeven]

I installed 2,0,11 and it works! This is really a great library!!! I am not strong enough to find out why 2,0,13 does not work ==> It would be nice if someone could put his teeth in it. I will recommend it to my friends.

[thelastoutpostworkshop]

Glad it's working now
