Additional MCU to ESP modul

[velja]

How to connect ESP modul with other MCU (AVR 90S2313)? What settings for ESPEasy to use?

My idea is that AVR MCU work some counting and calculation (wind speed, rain, wind direction) and in interval of 10 minutes ESP, which do some other measurements, call AVR and send all data to remote receiver.

idea 1
check out the promini extender plugin. it uses I2C to communicate between an avmega 328, but provides io extension only. this would need to be adapted to your idea.
idea 2
use dummy device on esp easy, connect serial between avr and esp, then use taskvalueSet function via serial ( not sure if this is possible)to write the data from avr to dummy device. dummy device should be able to send data to the controller

Hi,
I just create dummy device and can vrite from rules values on it but I don't know how make to write data from serial port (I use terminal program in this phase). How to connect serial port?



There are rules:
__________________________________________________________
on System#Boot do //delay 5 seconds to get the time
timerSet,1,5
endon

on Rules#Timer=1 do
TaskValueSet 4, 1, 11
TaskValueSet 4, 2, 22
TaskValueSet 4, 3, 33
TaskValueSet 4, 4, 44
endon

Check out http://www.letscontrolit.com/wiki/index ... _Reference According to this you can just send the command TaskvalueSet via Serial (meaning on AVR you say something like Serial.Print(TaskValueSet.....), so you should be able to use serial monitor of Arduino IDE to simulate this with a USB/TTL adapter (either a built on adapter like on NodeMCU/Wemos). Just type the command in the serial monitor and hit enter. Settings is 115200 bps

For the connection, ESP Easy uses GPIO 1&3 for Serial communication. Connect these to your AVR serial pins( often labeled UART). For in case you use an 5V AVR, its probably necessary to use a level shifter

By the way, why not use an ArduinoNano(clone), they cost about 3 € instead of AVR90S2313 and should be able to do the same?

So this is a point: How to populate values? I send characters through terminal, (via TTL adapter) but values stay untuched. How to write value for Sensor1 (Sensor2, Sensor3...) from serial device? When I use ser2net this characters went out to Putty terminal but Sensor1 value stay unchanged.

Ser2Net is definitly not what you a looking for, as it routes an Serial connection to an TCP connection (Telnet) and not at all what you are trying to do. Try the serial monitor from Arduino IDE, type

Code: Select all

TaskValueSet,4,1,11

then hit enter. Will try this at home later (if I find time)

i can confirm this works(with arduino serial moitor), i can write values via serial into dummy device. however strange enough, i had to first put serial log level to 4, before it worked. now after switching back to level 2, still works fine. you can also use this to let avr control outputs,

[velja]

I'll try tomorow morning.
Thank you

[velja]

Yes, it work! Now there is no problem with some interface that is not support by ESPEasy.

hello,
could you explain how to create the dummy device, I don't have in the list of possibles devices ?
I use ESP Easy R108
I would like to use the ESP module to send data from Wifi to a big display connected to the ESP via serial.
regards

under devices tab, just add a new device and chose dummy from the dropdown list

[38domo]

I don't have dummy in the dropdown list.
May be it is due to my version of espeasy. I use R108 for the moment.

True, you have to update

[38domo]

hello,
I have tried to update esp easy to V120 but obtain one error during compil:


error:
C:\Users\gegel\Documents\Arduino\ESPEasy\ESPEasy.ino:221:25: fatal error: ArduinoJson.h: No such file or directory

#include <ArduinoJson.h>

I have used espeasy sources v120 from github and replaced source and libraries to arduino lib and ArduinoJson.h is present in arduino\libraries\ArduinoJson
arduino ide : 1.81
esp8266 version 2.3.0
esp 12E selected

[velja]

Use firmware from
http://www.letscontrolit.com/wiki/index.php/ESPEasy

v120 (stable). Download and unzip. Then connect to to your device through serial communication or 192.168.4.1, option OTA upgrade. There is manual how to do that on ESPEasy wiki

[38domo]

hello, I have updated the version using flash.cmd included in the zip. Update OK. After reboot I can see now the dummy device in devices list.
I have now to understand how to send datas from mqqt to esp and to the serial port
regards

afaik taskvalueset command does not work via mqtt

[paxi]

You are right toeffel. But one can "wrap" that command in a rule and trigger this new event via mttq.

@38dome:
I haven't used it yet but from the description ser2net should be capable of what you're trying to to (send data to serial port) but you'll have to use telnet instead of mttq.

true, but how do you get the values to set?
They also Come via mqtt, or am i getting it wrong. Ahhh but the event value could work...just checked. Wrapping event in conjuction with %eventvalue% should work.

[paxi]

Yes, this should work for @velja.

Be carefull, @38domo kind of hijacked this thread and we're actually discussing two different topics here (desired direction of data flow over the serial interface).

[akulla]

Hello,

I am working on a home project with a arduino to get and process some analog values. I thought of using espeasy to get the data from the arduino via serial. First thing i try was to create a serial server device in espeasy and connect the arduino tothe esp via serial. Then with node-red i successfuly connect to the serial server tcp port and send data that i was able to see in the serial monitor(arduino serial monitor). But the problem is that i can not do the other way (send data from the serial monitor to node-red), there seems to exist some problem...
Then i come across this thread and saw the idea of set the task value of a dummy device via serial, beautiful!!! I set the dummy device and start receiving device value via MQTT that is a good solution too for me. The problem is that the command TaskValueSet,x,x,x does not work... So my question is anybody have done this with success? If yes i apreciate your help.

Thank very much.
