I CAN RUN SCRIPS BUT THEY STOP - CJMCU 3212 - INFO about wifiduck HOT 63 OPEN

The new "duck" works but sometimes script are not executed right ?

from wifiduck.

something wrong here perhaps ? not same connexion than model, so perhaps problem ?

try to change in source D1 (GPIO5) by D3 (GPIO0) ?

In config.h (ESP part) change
#define I2C_SCL 5
by
#define I2C_SCL 0

from wifiduck.

It looks like only serial is enabled, so that isn't a problem I think.

from wifiduck.

For me model gpio (describe on github project for DIY wifiduck) are not the same than on this hardware

@Z3R0NULL
have you try to change gpio for scl gpio from 5 to 0 in communication settings ?

I just flashed but it's still the same without any changes, it's still working but it stops sometimes... I'll upload a video of my error so you can analyze it better... @todely

I just changed ESP/Config.h like you said

Probably need to change somewhere else i didn’t check all the code bit ot’s explain on github project page : new connexion between esp and atmega from old duke to new duck

from wifiduck.

I will check when i will receive hardware but i’m pretty sure probleme come from this.

from wifiduck.

I have look the video ok

It’s our problem

from wifiduck.

@michalmonday have found same thing than me :i2c is not connected on 3212 but soldering missing 2 connexion is possible
@michalmonday where is j2 on the board ?

edit: found header pin

need to solder slc and sda to esp to make i2c work

@Z3R0NULL could you check if these 2 pin are not already connected to esp somewhere ? (With multimeter)

I'm not at home right now, tell me which pins you want me to check, I have a multimeter...

Draw them for me in the images that I sent you.. i Will check when i get back to home.

I just follow official tutorial for DIY on wifiduck, you see SDA is connected to SDA and SLC to SLC to talk by I2C protocol and not RX/TX
https://github.com/SpacehuhnTech/WiFiDuck#diy-hardware

if you connect wrong pin or touch 5v there is possible damage.
But wait i try by myself, easy to get in my country.

I have to find a smaller iron than the one i have or order small grip by the way.

Well, I'll wait.
you will be my hero.

I don't want to touch without knowing to not damage it.

but I think that impatience and curiosity won me over. 😅

i hope @spacehuhn reply to me i would like to get it working.
i posted the ATMEGA debug serial monitor but i wanna see more detailed debug but i dont know how to do it...
i wanna see the ESP debug how i have to do?

ill let this pics of my board

I think it is related to the error @spacehuhn :c
Maybe I have to change something for my hardware idk

im triyin to learn the languaje just for fix this error, would like help :c

from wifiduck.

i think the error is related by the times or something like that because, it run scrips sometime so it work fine, but sometimes not..
maybe is related to comunication times beetwen esp and atmega i dont know im talking from ignorance.

from wifiduck.

DAY: 3 - I am trying to communicate with other people who know about the topic. I hope they answer I've been trying to solve it for days and they are my last option.

from wifiduck.

DAY: 4 - I saw that I will not receive help soo, I started to investigate for myself. I have learned a lot about the arduino language which is based on C / C++ but I still don't understand the code of the Wifi_Duck project.

from wifiduck.

DAY: 6 - I can't, I already tried everything, I still don't want to give up but I don't know what to do anymore. One good thing is that I learned many things. Well I'll keep trying, never give up.

from wifiduck.

Hope find solution, i will get the same hardware

from wifiduck.

DAY: 10 - I think we're going to need help... I will upload a photo of diagram and my hardware modified.

IN THIS IMAGE WE CAN SEE PIN DIAGRAM TO FLASH ESP OR ATMEGA

HERE MY CJMCU WITH SWITCH

i solder a switch in CJMCU to switch between ESP or ATMEGA flash modes. GPIO0 & GND
It is a good hardware because it have 3 modules SDCARD,ESP,ATMEGA but there is not enough information.

from wifiduck.

Hope find solution, i will get the same hardware

You can do it work but with the old wifi duck repositori, i dont like the old because no languaje layout like EEUU,FR,AR,ES,JP, etc...

from wifiduck.

Hi, could you post your Communication Settings section settings from config.h files of both ESP and Atmega? No idea if that's the case but maybe you enabled both: I2C and Serial, and they sometimes interfere with each other because they seem to use the same buffer?

Yeah i think that i enabled Both i2c and serial idk maybe you can help <3
How should I configure the i2c or serial?... anyway, now I'm posting my Communication Setting..

from wifiduck.

My Communication Settings ESP/Config.h

My Communication Settings ATMEGA/Config.h

@michalmonday

from wifiduck.

It looks like only serial is enabled, so that isn't a problem I think.

the configuration when flashing can give problems?
I'm using this anyway...

Maybe that's the problem, why the old Wifi-Duck-Old repository works but the new one doesn't?

Maybe you have to adapt the Wifi-Duck-New code to make it work.

We have to look at the Wifi-Duck-Old code and adapt the new one from there... maybe change the GPIO code as you say?

Unfortunately I don't have the knowledge of electronics or arduino programming for that...

I tried to do this a few days ago, but failed.

I tried to pass the code from Wifi-Duck-Old to Wifi-Duck-New...
but it didn't come out

from wifiduck.

I just recorded a video.
as you can see in the video the script never ends successfully, but the atmega runs as a keyboard.

I have to say that sometimes the script does finish successfully.

@michalmonday have found same thing than me :i2c is not connected on 3212 but soldering missing 2 connexion is possible
@michalmonday where is j2 on the board ?

edit: found header pin

need to solder slc and sda to esp to make i2c work

@Z3R0NULL could you check if these 2 pin are not already connected to esp somewhere ? (With multimeter)

from wifiduck.

We are looking for where slc and sda are on the board, if they are free or connected to something

to make duck work i2c have to been connected between esp and atmega

solution is probably to solder slc and sda from esp to slc and sda on atmega (pin i have mark in red on board picture in my last post, you can try with small « alligator clip » to avoid soldering for nothing)

No continuity in both pins, im doing good?? IDK
How long for you get your CJMCU @todely ??

from wifiduck.

Ok so can you connect sda to sda and slc to slc with some grip or anything else ?
I will get it in 10 days i think

there is no possibility of it being damaged? or something?
because here in my country it is impossible to get these things, since amazon and those stores do not work.

from wifiduck.

After this defeat not sure i will tell you if it works !!
😇

did it arrive?
will you try it?
ooh i'm so nervous 😭
I hope it works.

from wifiduck.

Just kidding about football match argentina / french (i’m french)
Not arrive for the moment

Oooh i understand now 🤣🤣
I thought we would lose in the second half.
I went to the bathroom one minute and when I got back France had 2 goals 😯.
here in Argentina people turn crazy in the streets.

And how Long to it to arrive?

from wifiduck.

hope you have a nice Christmas.

from wifiduck.

Yup, so how are you.
Is there any news about that?
😅

from wifiduck.

Hello how are you, I decided to take a risk xd.
since I have it saved and if I don't risk it I won't be able to use it.
But I need a little of your help. I only have to solder those wires or what? Can you guide me? thank you very much :D

from wifiduck.

Hello !
I have check and item is moving from china today (after 1 month stay somewhere...! )
Expecting a delivery in few days (it was a 10 day delivery)

If you wanna try you need to test with some electronic grip (better than soldering for testing purpose)

from wifiduck.

Receive, use i2c for communication between esp and atmega
Wifi server is ok

Does you have a script who doesn't work for you ? (The one in your video have error on "ctrl+", i have to remove this line)

Edit:
Parameter in esp sketch

from wifiduck.

Soo
Hii... did you manage to make it work? does it work fine and no errors?

from wifiduck.

Everything seems to work but your script (in your video) have an error on line "ctrl+"

Does you have a script not working For you and you want i try ?

from wifiduck.

Hey @Z3R0NULL pudiste darle solucion al problema?

Hey @Z3R0NULL pudiste darle solucion al problema?

Nope, and you?
i think the jumper is the only option like todely says in te comments.

from wifiduck.

@Z3R0NULL Any idea what going on?

from wifiduck.

I think should make mouse move little bit to fix it, but it doesn't quite make sense.

from wifiduck.

Any update?

About what?

from wifiduck.

Any update?

Hello, I already have my CJMCU 3212 working correctly, you just have to make a jumper as Todely says, from the pins marked in the image SDA TO SDA AND SDL TO SDL from the esp to the atmega

Check The images above
