Connecting a TM1637 4-Digit Display

Message

victorclaessen · #121 Post by **victorclaessen** » 04 Mar 2018, 14:24

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?

papperone · #122 Post by **papperone** » 04 Mar 2018, 20:32

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...

soif · #123 Post by **soif** » 04 Mar 2018, 21:56

thanks for your GREAT work ! I'm sure that you will clear this better for all of us ASAP ! cheers

BTW my display has NO colon, but just dots (x4)

papperone · #124 Post by **papperone** » 04 Mar 2018, 22:09

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

soif · #125 Post by **soif** » 04 Mar 2018, 22:13

BTW can someone owning one of the "OLD" displays can CONFIRM
that it still works with my latest (merged) PR ?

if you only changed the timing I can confirm it works, as I own as well some old displays and even increasing the delay they keep working...

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...

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!!!

I split both PRs.
Can you have a look at this one to check I took the correct version?
https://github.com/letscontrolit/ESPEasy/pull/1043
Then I will merge it.

Thanks TD-er, really apreciated the help and sorry for the mess!

@everyone: new P073 is on GitHub, supporting below modules; please test all modules you have and report to me eventually any bugs found.

MAX7219 8digit

TM1637 4digit (colon)

TM1637 4digit (dots)

TM1637 6digit

**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"

hello, I have tested this week end : wemos D1 with display 4 digit with colon & dots.
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)?

Or maybe refer to the pictures I've postes fwe message before...

Is it possible to use multiple LED displays at once ESP ?

only one works

boolie · #138 Post by **boolie** » 23 May 2018, 21:45

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

papperone · #139 Post by **papperone** » 23 May 2018, 23:59

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?

warcz · #140 Post by **warcz** » 24 May 2018, 11:46

I should have asked before I bought 4 pcs

( Thank you for your info. Good luck with upgrading

]

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!

alex77k12 · #142 Post by **alex77k12** » 30 May 2018, 10:18

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

papperone · #143 Post by **papperone** » 31 May 2018, 06:31

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!

papperone · #144 Post by **papperone** » 21 Jun 2018, 07:10

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...

alex77k12 · #145 Post by **alex77k12** » 22 Jun 2018, 18:02

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?

With the free text command you can show whatever you want, you have all numbers, letters and special chars as per my post above...
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

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.

good point, I will add it and post PR later today but I need clarification how the 12h clock works (I'm 24h user

- midnight or noon should show as 00:00 or 12:00?

Yes, only difference is that 00:00 marks START of day. Which is used to differ the times when showing buss, train, airplane departures etc

papperone · #160 Post by **papperone** » 01 Aug 2018, 10:28

Sorry I just come back and I thought I explained I had no time to submit the new plugin as I prefer to run some more tests before releasing it.
Still it won't be supporting multiple display (I have to check what changes are needed to handle this last feature...)

velja · #161 Post by **velja** » 01 Aug 2018, 11:24

What a pity! I wait with my two displays to monitor IN/OUT temperature!. I hope you make it soon!

papperone · #162 Post by **papperone** » 12 Aug 2018, 10:28

sorry about delays but while I was finishing the testing some other user commited in GitHub a change request of my plugin with huge nuber of changes aiming to optimization...
long story short as I had already heavily changed the cosde to implement all new functions now I'm puzzled how to proceed

- I can choose to revert back to my version of the code, throwing out all optimization submited (no idea about what was done as the othe user change lots of the original code)
- I can start again all coding of new features on the actual version of the code but first I need to understand the changes, test if it's all working as it was wil all the supported hardware

No matter what way I will go it will take lots more unplanned time which I have not much recently due to job related tasks...
I do apologize but not all depending on me!

ronald · #163 Post by **ronald** » 12 Aug 2018, 11:49

Too bad, all this hassle. It works great the way it is now. Why did someone just change that much of your code?
In your place I should revert back to my original code. If the other user wants to change it, let him develop his own version.

Indeed, it is not merged, so we can continue with your code and maybe later apply the mentioned optimizations when still applicable.

(placing char arrays or strings in flash is always a nice to have optimization)

hi
1st: thanks for your work

2nd: i've some of the "dots+colon" tm1637 modules, and using ESP_Easy_mega-20180809_dev_ESP8266_4096.bin on a nodemcu model, 1st gpio D3, 2nd gpio D4, tried both the dots and colon combo option, but none of the dots or colon is ever ON, just the numbers (right now showing time)... not in blink, nor in no blink setting...

3rd: sending this command "7dn,09.07" in manual mode just displays "9", why?

4th: are, or will ever be, these modules supported? https://it.aliexpress.com/item/74HC595- ... 25544.html
some info about them: http://vlad-gheorghe.blogspot.com/2018/ ... hc164.html
