Re: Connecting a TM1637 4-Digit Display
What a pity! I wait with my two displays to monitor IN/OUT temperature!. I hope you make it soon!
Re: Connecting a TM1637 4-Digit Display
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!

Re: Connecting a TM1637 4-Digit Display
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.
Thank you for all the effort you put into it.

Re: Connecting a TM1637 4-Digit Display
@papperone, was it me that made changes?
I don't remember changing things to your plugin.
Maybe I can help explaining what has changed recently and to what purpose?

no TD-er, it was an user I've never heard of "GHolli" in --> https://github.com/letscontrolit/ESPEasy/pull/1631
what shoudl I do ? as I wrote the number of changes in the plucing are a lot and to go to all of them it will take me a while and I've already a local version of plugin with new features based on my old versione...

I say: continue with your local version. You started it and it worked great. Why wait for some unknown user that teared your code apart?

Still, it's only a PR, not merged. So if your update of the code is working good we'll just reject that PR and merge your change. Good jobpapperone wrote: ↑12 Aug 2018, 12:58no TD-er, it was an user I've never heard of "GHolli" in --> https://github.com/letscontrolit/ESPEasy/pull/1631

Re: Connecting a TM1637 4-Digit Display
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)

Re: Connecting a TM1637 4-Digit Display
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

an other request, for help

Could a new "Display Output:" mode be added so as the clock mode can chose between a 12hr Clock or the existing 24hr Clock

Re: Connecting a TM1637 4-Digit Display
Hmm, With the MAX7219 everything works fine, but with the TM1637 4-digits, it doesn't work. I tried several diferent Displays, none of them works. No LED ist on What can I do?

Re: Connecting a TM1637 4-Digit Display
Yes, some of my TM1637 are exactly the same model that is shown on the pics in the wiki. tried to use the same gpios (and others) tried with 3.3 V and 5V, tried ESPEasy builds from 20000 to 20102, tried the special compiled version earlier in this thread here (somewhen in 2017), tried several esp8266 devices (wemos D1 mini and clones, NodeMCU) nothing worked for me. No reaction on the display.

Re: Connecting a TM1637 4-Digit Display
Not at the moment, because of my banning problem, you know.
but there is nothing special to see i think. Wiring and config is exactly as in the wiki, I tried to switch the two GPOs, too and many other things, like changing the GPIOs to others, 3.3V and 4V and so on.
I know, it is hard to help me with that

Re: Connecting a TM1637 4-Digit Display
OK, I made a new firmware and set PLUGIN_73_DEBUG to true, maybe this helps? In the log it loops "7DGT: Comm ACK=FALSE" and "/DGT: WriteByte"... Like there is no connection. Used a fresh Wemos D1 mini and GPIO 0 and 2 as in the example (wiki)... And sorry for my bad english
Re: Connecting a TM1637 4-Digit Display
Checked my hardware with https://wifi-iot.com/ and it works. So it's a problem in the plugin I think...
Re: Connecting a TM1637 4-Digit Display
OK, it works with 2.0 build 20000 stable, compiled it myself from github (never done this before yesterday, I am a little bit proud of this )
So I think someone else could look how to get it to work on 20102...
Would be great if this works on an ESP32, too
Edit: do you think it is possible to share the clk gpio for multiple TM1637 or something like that? I am a little bit low on GPIOs...

Re: Connecting a TM1637 4-Digit Display
Hi,
I can confirm that tere seems to be an issue in the actual (nightly) releases.
I have a TM16037.
With ESPEasy_mega-20180815 the display is working fine.
With ESPEasy_mega-20181008 it does not work.
For now I can stoy on the old one but would be great to get it "back" in the latest releases.

Re: Connecting a TM1637 4-Digit Display
Sorry for the delay but finally I managed to release new version of my plugin (thanks to TD-er to help on sort out the mess!).
Below new functions/commands available, still not able to work on the issue that does not allow multiple displays
Obviously some of the letters can't be shown properly but it's a limit of the 7 segment layout.

Re: Connecting a TM1637 4-Digit Display
I tested again (as I do have it) both these displays and as well the ones based on TM74HC595 and I can confirm they are not usable with ESPEasy as they do require a 50Hz refresh (e.g. they must be refreshed at least 50 times per seconds as they are built with shift-register ICs).mrshark wrote: ↑14 Aug 2018, 14:14 are, or will ever be, these modules supported? https://it.aliexpress.com/item/74HC595- ... 25544.html
If you have additional displays to test and evaluate if to add them please let me know, meanwhile I will work on a new plugin to support MAX7219 dot-matrix displays

Re: Connecting a TM1637 4-Digit Display
wow that's massive, but at that level I would rather implement a real RGB dot matrix display like this https://www.aliexpress.com/item/P3-RGB- ... 85432.html
it's twice bigger and cost much less (by the way I've one of this at home, so sooner or later.... )

Re: Connecting a TM1637 4-Digit Display
Obviously I miss something - Is it solution for two TM 1637 displays release or not?
Colon AND dots?
I have a four-digit display with both, dots and a colon (8.8.:8.8.). It seems that I cannot address the dots. In temperature display mode the colon is used as decimal separator. It doesn't make a difference if set the plugin to address a display with dots.
Is it even possible to use the dots or individually turn the colon on or off?

Re: Connecting a TM1637 4-Digit Display
Not yet, still need to rework some part of the plugin to enable multiple displays handling... sorry !
I think I wrote it somewher but all of the modules I've tested with this configuration (colon+dot) have only one of the two connected (and most of the times is the colon ).oisisi wrote: ↑02 Dec 2018, 09:06 I have a four-digit display with both, dots and a colon (8.8.:8.8.).

if you need to display temperature, as I use the colon as decimal separator, you can mask/hide with black tape the "top dot" of the colon and you have a reasonable solution, unless you want to replace the display with one with dots enabled...

Re: Connecting a TM1637 4-Digit Display
Thanks for your quick response. I've seen several remarks online where people came to the same conclusion. I'll see if I can get to the dots with this library.
Re: Connecting a TM1637 4-Digit Display
After extensive testing it seems mine is also one of those. I was hoping to use the dots as additional status indicators. I guess I have to add separate LEDs for that to my project.
I have a different remark though. It seems one can switch only between manual mode and clock/date display via the plugin's page. Wouldn't it make sense to allow the switch to be made via command?
Re: Connecting a TM1637 4-Digit Display
well never thought about it as I couldn't think of a use-case scenario where this can be used, if you think it make sense to add this let me know how you intend to use, I don't want to add features just for the sake of it and increase code size without realy application...

Alternating between clock and outdoor temperature is one example or clock plus room CO2 level, another example.

Re: Connecting a TM1637 4-Digit Display
To be able to change modes remotely per command generally makes sense, imho. What would happen if you just remove the break from the command functions?
Re: Connecting a TM1637 4-Digit Display
Not sure it's a good practice, I will implement new command to change module mode so user can use it in rules with timers...
Ok you are right, you gave me some idea how to improve one of my modulegrovkillen wrote: ↑02 Dec 2018, 20:51 Alternating between clock and outdoor temperature is one example or clock plus room CO2 level, another example.
Let me find few minutes later this week and I will implement mode-change command indeed!
PS: I'm just not sure what will happen when I will make multiple display works, as they are now commands are not able to point a specific device and they will be exectuted only by the first occurrence of any given plugin

Re: Connecting a TM1637 4-Digit Display
Yes we need to be able to point which display/task number the command is addressing. But that is core development on a more generic level.

I've bought it here: https://www.aliexpress.com/item/1PCS-4- ... 4c4duUAft7 but seems I've got a newer one as the label on it says "V1.1" rather than "V1.0".
I think I've tried all possible settings combinations and all supported commands from wiki but no luck - I can't get it to work - it looks turned off all the time.
The device itself is fine - I managed to run it following that: http://www.esp8266learning.com/tm1637-7 ... xample.php.
Could anyone advise?

Have you tried to swap CLK and DIO pin setting on the device config (not touching the physical wiring)?

Re: Connecting a TM1637 4-Digit Display
Yes, I have. Tried to change the settings, rebooted D1, played with display output (manual, date, etc), run some commands (cmd=7don, cmd=7db,15, etc) - still no reaction from the display :/
Re: Connecting a TM1637 4-Digit Display
that's vcery weird as all my displays of different brands and configuration works perfectly...
as well the code in the plugin is writte following the spec of the datasheet of the supported IC, which I guess it's the same with the library you pointed and it's first time I've got reported such behaviour (plugin does not work while the library does)...
I coudl look into library but honestly I've lack of free time due to my job so not sure when I will be able to do it and on top of it I've not hardware to test so it will make this debugging very tricky!

Re: Connecting a TM1637 4-Digit Display
I think i'm in the same boat. I can't get my 7segs to display. I've 3 setup from a while back which are working fine, but I've ordered new ones and none of them are displaying. I've verified they work using the same script as you mentioned:
