Hi Poki,
I checked and tested various encoder, and I have had multiple response different from different encoder.
So my solution to cover is this:

 #define BASIC_ENCODER_ALGORITHM
// #define MISCHIANTI_ENCODER_ALGORITHM
// #define SEQUENCE_ENCODER_ALGORITHM_REDUCED
// #define SEQUENCE_ENCODER_ALGORITHM
// #define POKI_ENCODER_ALGORITHM

I give the possibility to use different algorithm for different encoder like this

void updateEncoder(){
    changed2 = pcf8574.readEncoderValueSequenceReduced(P6, P5, &encoderValue2);
    changed = pcf8574.readEncoderValue(encoderPinA, encoderPinB, &encoderValue, true);

//  int vale = pcf8574.readEncoderValue(encoderPinA, encoderPinB);
//  if (vale!=0){
//      changed = true;
//  }
//  encoderValue = encoderValue + vale;

    bool val = pcf8574.digitalRead(P2);
    if (val!=valPrec){
      changed = true;
      valPrec = val;
      encoderButtonVal = val;
    }
    bool val2 = pcf8574.digitalRead(P4);
    if (val2!=valPrec2){
      changed2 = true;
      valPrec2 = val2;
      encoderButtonVal2 = val2;
    }
}

With this solution I can use different modules and different encoders with succes.

Give me a feedbback.
Bye Renzo

There is another bug

byte encoderValues = B00000000;

must be

volatile byte encoderValues = B00000000;

Try It also please.
Thanks Renzo

Hi poki,
I had tested with 2 encoder and BASIC_ENCODER_ALGORITHM work fine for me, but with yours first encoder only increase.

But I’m going to to do more test.

Hi Poki,
thanks for your solution, but your solution not work with my encoder, the first encoder only increment when rotate, the second work correctly.
I think there are some difference from the encoder, so I’m going to add you r algorithm to the library for all people that have your same type of encoder.
Now we have:

#define POKI_ENCODER_ALGORITHM
//#define BASIC_ENCODER_ALGORITHM
//#define MISCHIANTI_ENCODER_ALGORITHM

Thanks for your support.

Hi poki,
change this lines

// Select an algorithm to manage encoder progression

#define BASIC_ENCODER_ALGORITHM

//#define MISCHIANTI_ENCODER_ALGORITHM

comment MISCHIANTI_ENCODER_ALGORITHM and decomment BASIC_ENCODER_ALGORITHM, and give me a feedback.

Thanks Renzo

Hi Poky,
I never test the internal implementation with 2 encoder, It’s possible that there is a bug,

to bypass the problem you can try to implement externally the management of 2 encoder, there is an example of external implementation on the relative tutorial

PCF8574 i2c digital I/O expander: Arduino, esp8266 and esp32, rotary encoder

But I try to fix as soon as possible.

Hehehhe,

no no, sorry, I did not understand, and I have not included examples that use pins different from the standard.

Instead of use this constructor

DHT12 dht12;

you can use this

DHT12 dht12(D1, D2);

and you can specify the alternati pins you want.

I think It’s what you need.

Hi Mohammed,

I use this declaration

uint8_t sdWrongReadNumber = 0;

You can find the complete sketch of the Power One aurora Inverter at this link.

GitHub repository of ABB Aurora inverter web interface.

If you need more info, ask.

Bye Renzo

Hi Dave,

I think you don’t need to use alternate pins, you can connect more than one device to the same 2 pins, you must only put the a different address.

Usually there is one master and one or multiple slaves on the line, although there can be multiple masters, but we’ll talk about that later.

Both masters and slaves can transmit or receive data, therefore, a device can be in one of these four states: master transmit, master receive, slave transmit, slave receive.

You must pay attention only if you manage i2c with interrupt.

 

Tell me if this can be a solution.

Hi mohammed,

there is a topic with the informations you need, here you are

Send a simple mail including the value of a declared variable in the message

Bye Renzo

[Renzo Mischianti]

Hi Martin,

any news?

Bye Renzo

[Renzo Mischianti]

Hi Mohammed,

to send email from your iot project you can follow this guide

Send email with attachments (EMailSender v2.x library): esp32 and esp8266 – Part 2

[Renzo Mischianti]

It’s strange,

please check the connection schema, and tell me, all the data that device return It’s wrong.

Bye Renzo

[Renzo Mischianti]

Hi Jones,

I check and seems that esp8266 have TwoWire and I think I must include in esp8266 implementation.

I try to test.

Bye Renzo

[Renzo Mischianti]

I had thought about that, but the problem is that I must add an identification that use some byte (58byte is the limit of the packet) to identify the ack of the message and so lost a lot of space.

And the other problem is that when receive message from multiple device, so I must add another id for the device, and lost other space, It’s a problem.

I can’t find a generic solution without use a lot of resources.

Bye Renzo
