I have found interesting things, if i cut the 3,3v powersupply of the arduino, it still running, gets power from the d-pins of the esp. Bacause of an mistake i burned the arduino, tomorrow i will try a new one, try to use ProMiniExtender module to talk with it instad of using pwm signals. i will go ...

No, Same Result with DI4007

Hello,

i'm using a ESP8266 to check the speed of a Fan.

I tested it with 5 and 3,3V input, in both ways i get a result vor a short time, than the ESP does a reboot.
Is Puscounter is disabled, the ESP runs.

any ideas?

Best regards

Michael

Leider keine Verbesserung, nicht auf LOW/CHANGING/RISING/FALLING TOTAL oder Total oder Count lassen sich nicht abspeichern. Ich habe jetzt meinen Arduino dazwischen, der mir ein PWM Signal von 0-1000 liefert, der Lüfter ist nicht mehr direkt angeschlossen. Trotzdem kommt nix an. :-/ Unter Hardware s...

I got no Reaktion

Is there anybody with an idea to read Pulse from an Input Pin an use it in rules?

Arduino

is it necessary to use Raw commands?

OK, now i have enabled Rules in Advanced settings, have a Clock Event:
How can i get the pwm value from GPIO?

can you build a smal totorial?
i have no idea to get this value in the dummy

sorry, thats to high for me, please help.

now i have a PWM inputsignal on GPIO 4 and GPIO 10 build from my Fan Arduino. 0 to 1000 mapped from 0 to 2500 rpm of fan. (Fan1 and Fan2)

what have i to do to see this PWM signal anywhere? maybe dummy.

ok, i undestand that there is no way to do it nativ on EasyESP, i could calc it to pwm with my buildin arduino.
Is it possible to get this pwm value, as it is possible to set pwm values?

best regards

Michael

Meine Lösung

Hallo Zusammen, gibt es eine Möglichkeit mit EasyESP die Geschwindigkeit eines Lüfters auszulesen? Mit Arduino würde ich das so lösen: // Konstanten const int tachoPin = 2; // Pin des Tachosignals des Lüfters // Variablen float rps = 0; // Variable mit Kommastelle für die Berechnung der Umdrehungen ...

Problem solved with PWM communication.

because it is not possible to change internal timing of ESP8266.

My new idea is to talk to an arduino, give him 0 to 5V to convert it in percent and control pwm fan with the arduino, without noise.


4V = 80% speed

the result of adding the condensator is that speed is always i think 100%

is it posible to use 2 outputports to set a voltage from 0 to 5 V or 0 to 3,3 V.

like 80% = 4V

did it somebody with existing modules?

in witch way would you build in the capacitor?
pwm + and ground - ?

I had testet with case PLUGIN_INIT: { // add this line analogWriteFreq(31300); //should give 31300Hz // go on with existing code no reaction, same result, fan is making noise if it is set under pwm 900 on arduino is no noise with void setup() { TCCR1B = TCCR1B & 0b11111000 | 0x01; // Setzt Timer...

Hello, I have a Problem with hard coded frequency because of noices that a PWM controled fan does if you don't bring it into an area where you cant hear it. In arduino you do it like void setup() { TCCR1B = TCCR1B & 0b11111000 | 0x01; // Setzt Timer1 (Pin 9 und 10) auf 31300Hz } what have i to d...
