Re: Connecting a TM1637 4-Digit Display
ESP-01 has only 512k memory, so we cannot install v2.00 or mega version
Re: Connecting a TM1637 4-Digit Display
Hi papperone,
I have posted a problem I have with SendToHTTP in this thread. I am informing you as well, in case it relates to your build.
Thanks!

Re: Connecting a TM1637 4-Digit Display
Nope.
The old version (Usually on a blue PCB) has 512K
Newer versions (Black PCB) have 1MB and can be used with the 1024-Binaries of ESPEasy 2.0.0/Mega.
Please beware:
At this time there are some ESP-01 with a PUYA flash chip.
These flash chips do not work with ESPEasy atm, they have a problem with SPIFFS memory.
This problem is under investigation, but that will take a while.

Re: Connecting a TM1637 4-Digit Display
There is solution, but we still have to implement it.
Re: Connecting a TM1637 4-Digit Display
Nice! Good job.
But still no solution that is ready to use

Re: Connecting a TM1637 4-Digit Display
I received finally the new 7digit modules with M1637 and new config (6 digits and with decimal dots).
I will try to find some spare time to update the plugin to have support for them, about the SendtoHTTP bug I don't this can be connected but I'll have a look.

Re: Connecting a TM1637 4-Digit Display
Either I'm not lucky at all (and I got 4 DOA brand new displays from Robodin) or something is weird here...
None of the brand new 4 displays I've got, despite I bought branded ones, seems to work![Bedroeft :(](./images/smilies/icon_e_sad.gif)
@Grovkillen: can you connect one of the new type of displays you got as well and see if they react with old plugin? they are pin to pin compatible so at least the digits shoudl be shown...

Re: Connecting a TM1637 4-Digit Display
Meanwhile I've found last night a differen library for Arduino (not working on ESP8266) which can drive both old and new type of displays...
That's weird as they both uses TM1637 and I build the plugin from scratch using the info taken from the IC datasheet, but... obviously I overlook something or the new display have something different which I cannot still spot.
Anyhow I think it will take longer than expected as I will need to reverse engineer the new lib I've found to understand how it is driving the IC and to implement the same changes in my plugin (which does not uses any library).
I do apologize for the delay![Bedroeft :(](./images/smilies/icon_e_sad.gif)

Re: Connecting a TM1637 4-Digit Display
hello,
on my side I have made supplemental tests. I have 2 displays available
First test: connect on arduino Uno with a small prog to display random data --> OK on the 2 displays
2nd test : connect on Wemos with espeasy v2 : No. don't work- no display
3d test : connect on ESP12E with espeasy V2: NO- don't work- no display
espeasy works fine on wemos and esp12 with gpio tests ( leds connected)
As there is a level potential issue on the displays (5V on arduino, 3V3 on ESP) I have ordered level shifters to check.
regards

Nevrtheless on a bare ESP8266 with the original library I've the same behaviour while using a different library I'm able to drive both old and new type displays.
Something must have changed in the TM1637 IC as there's no other explanation nor components on the module to explain such behaviour; I'm currently working to understadn the difference between old and new library to fix the plugin...

Re: Connecting a TM1637 4-Digit Display
I just wanted to add that I bought several of these units and unfortunately they also don't work with this plugin. There is no output visible. They work from Arduino or from Raspberry Pi. Weird, right?

Re: Connecting a TM1637 4-Digit Display
I have made a PR here:
https://github.com/letscontrolit/ESPEasy/pull/996
This PR fixes the No Display (+ also hangs, crash, etc...) issue for a recent (RobotDyn in my case) 4seg display, using a NodeMcu v2.
You can test it by compiling my branch fixTM1637
Please reports IN THE PULL REQUEST ONLY :
- does it STILL work on older displays (that used to work with the previous code) or not?
- is it stable (no over Load usage, or hangs) or not?
- is it working with your recent displays?
if it doesnt work on your diplay , you can experiment with a bigger TM1637_BIT_DELAY, ie 100, and report
If it is reported to work on both old and new displays, maintainers will certainly merge it fast.![Mr. Groen :mrgreen:](./images/smilies/icon_mrgreen.gif)

Thanks for the proposed fix. Would it be alright to trouble you for the compiled firmware; i.e. would you be willing to post that somewhere? Preferably for a 4M-version ESP8266?

Re: Connecting a TM1637 4-Digit Display
Ah, right. I can confirm that my TM1637 units (the ones obtained here: https://nl.aliexpress.com/item/4-Digit- ... 69551.html) work. Thanks for fixing this!
By the way, when I send "7dn,8.5", the display reads "8", where I would expect it to read "8.5". And when I send "7dt,8.5" it reads "8:5°", where I would expect "8.5°". Is my expectation wrong, or could this be an issue related to this specific module? Any thoughts?

Re: Connecting a TM1637 4-Digit Display
Thanks for the quick PR but I had already fixed the timing issue; I am still working to handle better this new display which has both "dots" and "colon" (that's causing the strange behaviour of last post from victorclaessen).
As soon as it's completed (including the handling of the 6-digits TM1637) I'll make the PR in order to have it tested...

Re: Connecting a TM1637 4-Digit Display
yes, I know, so far i've got 4 different displays (I've received all of them so I can test all before to release next version).
1) 4 digits and only colon
2) 4 digits and only dots
3) 4 digits with both colon and dots
4) 6 digits with dots

Re: Connecting a TM1637 4-Digit Display
Unfortunately after some struggling and reverse engineer of module (3) I've found out that despite the display has both "colon" in the middle and "dots" after each digit the "dots" are not connected to the TM1647...
![Bedroeft :(](./images/smilies/icon_e_sad.gif)
Long story short, module (1) and (3) behave exactly the same, so I removed module (3) from the drop down, already implemented module (2) and tested.
As it's late and I've lost my focus on coding I'll finish implementing module (4) tomorrow then will make the PR (after verifying that MAX7219 still works and I've not broken anything!)

I tried to commit the new version of the pluing into the 2.0 branch but for some reasons GitHub desktop still keep adding it to the HLW8012 PR which is pending since month waiting for a solution.
Despite in GitHub I created a new PR when I try to merge it GitHUB (on the web) keeps adding anythign to the previously opened one.
If someone can explain how I can make GitHUB desktop understand I really want a new commit separated from the pending one(s) it woudl be very apreciated!!!

**NOTE** if your TM1637 4-digit module has both colon and dots most probably only colon is connected thus it will work same as the one described as "TM1637 4digit (colon)"
Please forgive me the bad code but those modules are really weird, most of them the digit addresses are in the right subsequencial order (e.g. 1234 or 12345678) but the ones 6-digits I've got have all swapped order "321654"

It's works fine . thanks a lot for the development.
I can manage the brigthness using the web interface but how can we manage the brightness by command (http/mqtt or Rules)?

Re: Connecting a TM1637 4-Digit Display
Is it possible to use multiple LED displays at once ESP ?
only one works

Re: Connecting a TM1637 4-Digit Display
Hi, Papperone,
I'd like to create a bit more flexibility in what the plugin can display on the 7-segment modules, to allow for some alpha characters (I want to be able to indicate an error condition and loss of wifi, that sort of thing... Err, dISc, Off, ...)
I was thinking of copying the plugin and making the changes in the playground, but then I found this thread and I see that you've had to do some "interesting" stuff to make the code work with the different versions of the TM1637, so I thought maybe it would be better to suggest the changes to you and see if you have the time to make them, rather than for me to break something!
What I'm thinking, is:
- 7db,n,n,n,n for binary data - each 'n' would be a decimal value 0-255 representing the binary bits sent for that digit of the display; this allows us to switch on any combination of segments;
- 7ds,"ABCD" for string data (e.g. hexadecimal or text)... the characters AbcdeFhIJLoPStuy should all be possible to create with 7 segments.
What do you think, is that something you could do, or is it better if I learn how to modify the plugin and try my skills?
Thanks!
Jeff

Re: Connecting a TM1637 4-Digit Display
1) yes currently only one display is allowed, still need to spend some time to implement multiple displays...
2) definitely yes, it was somethign planned to add alphabetical chars but still not done; I'll fin dsome free time to implement this new features and will take your suggestion but I'm puzzled what is the application for the "binary" feature you asked, can you please elaborate more?

The "binary" idea was to allow any arbitrary pattern that the user might want to display - maybe "=", three bars, two vertical bars, etc. The controller chip takes 8 bits of data per digit, so I was thinking that those could be encoded by the user/user code into a 1-byte number (0-255) and then 4 (6, 8) of those passed to the plug-in which would simply send on the bit patterns to the display chip.
That said, if we extended the alpha character set to include "=", "-" and "|" then I can't really think of any other patterns that one could make so the binary probably isn't going to add anything!

Re: Connecting a TM1637 4-Digit Display
I was trying to apply MAX7219 along with the encoder, I wanted to display time, date, temperature, humidity in the room and temperature and external humidity, taking data from another module. I can use the rules to display rotating encoder temperature and humidity (without the letter) but I do not know the command to display time and date, if in the rules impose% syshour%, %sysmin% or %systime%, does not happen as clock set in device, what is the correct command?
Sorry for my english using translator
Congratulations again for the work done, I really like it
PS if I use the command 7dn,[Clock#Time] the system crashes and restarts

Re: Connecting a TM1637 4-Digit Display
I did not plan in the plugin to be able to show date/time manually with a command rather than automatically...
I noted this as new future fature to implement in next release, thanks!

Re: Connecting a TM1637 4-Digit Display
testing new functions as below; please let me know asap if anything missed so I can still add it before new plugin release:
- new command "7dst,<hh>,<mm>,<ss>" - "show time" in manual mode
- new command "7dsd,<dd>,<mm>,<yy>" - "show date" in manual mode (if <yy> <100 then 2000 is added, only valid for 8 digit displays)
- new command "7dtext,<text>" - "show text" in manual mode; supported chars --> 0-9, a-z, A-Z, space, "-", "_", "=", "^" (shows degree symbol), "/" (shows three horizontal lines)
still multiple devices are not working, this will require more time to fix it...

Re: Connecting a TM1637 4-Digit Display
For those using the 8-digit display could you put two values together, for example temperature and humidity? Thank you again for the work you are doing. Thanks to your work I'm creating a bedroom object rack.Only a question, as regards the text will it be possible to merge it in the same string of a value, such as humidity alongside an H?

I believe you just need to create a rule to update the display at your preferred interval and you shoudl be able to combine 2 values coming from other devices/sensors
PS: I think lot of people here can be interested in your project if you would like to share it

Re: Connecting a TM1637 4-Digit Display
I have a Wemos D1 Mini running "ESP_Easy_mega-20180618_test_ESP8266_4096.bin" - very happy as it is working well, with a TM1637 4-Digit Display,
Could a new "Display Output:" mode be added so as the clock mode can chose between a 12hr Clock or the existing 24hr Clock ? blinking is good.

Re: Connecting a TM1637 4-Digit Display
give me some time that I try to organize the files and I share them in some way. If you are interested I am doing the project for printing the box with 3D printer, I can possibly also share that once finished
Re: Connecting a TM1637 4-Digit Display
good point, I will add it and post PR later today but I need clarification how the 12h clock works (I'm 24h usermiah wrote: ↑26 Jun 2018, 13:40 I have a Wemos D1 Mini running "ESP_Easy_mega-20180618_test_ESP8266_4096.bin" - very happy as it is working well, with a TM1637 4-Digit Display,
