Tetris Clock using an LED Matrix and an ESP32 (without RTC)

[@toblum]

Nice to see that the good old TetrisClock library is getting some attention again. I haven't been able to do as much of it over the last few months as I wanted. I don't really understand why it doesn't want to run on the 8266 anymore. I‘ll test this out with my spare 32x32 matrix, which I have here laying around.

[@BrianLough]

thanks for all the hard work on it! I'm sure I broke it whatever I did! It would be great if you did, I think the main problem is trying to run the animation in a ticker. Tabltronix did some good research into it on an issue for the Tetris clock sketch

[@GreenOnionBrother]

Have you figured out out yet? I can't seem to get it to work either. (not that I'm particularly qualified)

[@toblum]

@@GreenOnionBrother Unfortunately I didn't find time to look deeper into it, so far. But I could make the original version (github.com/toblum/esp_p10_tetris_clock/) work on my new matrix. But I also had issues with tetrisanimation lib.

[@LaurentPerrinlolo]

​@@toblum It is not possible to execute delay() or yield() from an asynchronous callback. Adafruit_GFX::writeLine() is calling yield(). Therefore, you cannot call any primitives drawing lines from a ticker. Interestingly, if you use a scale of 1 and no colon, everything works fine. Else, just set a flag in the ticker and draw in loop(). Works well.

[@toblum]

​@@LaurentPerrinlolo Thanks for your feedback. I'm trying to find time to revisit that project soon. I'll try to remember your message when I have a look at it again. Or if you have a improved version, please feel free to send over a PR in github.

Hi Brian, just finished a build of this clock using your tinyPico and Matrix. Was very easy and it looks great. Many Thanks! for a great project. Did have one issue (fixed now) and wanted to feedback to help others. Clock had 2 horizontal bands of missing pixels about 3/4" wide. The trouble shooting section of PxMatrix library provided the answer: add this line to code: display.setMuxDelay(1,1,1,1,1); I put it at line 234 just before buffer flush in // Intialise display library section. Adds a 1us delay to each of the A-E channels. Guess panel I purchased has a slow multiplexer.

Brian thank you for this project, this was fun to do. Appreciate all your work and am subscribed to your channel now. Nice writeup in Hackspace magazine!

[@AJB2K3]

Liked straight away because of the Tinypico plug!

[@SleepingMage]

I'm definitely gonna be making this, I love Tetris! ❤️

[@rosscastona7809]

Thank you for your Tetris Clock project. I don't know what I'm doing ha,ha. But after a few weeks I got it to work. I needed to add more code to the sketch to get my panel to display properly. // Set the number of panels that make up the display area width (default is 1) display.setPanelsWidth(4); That took care of my problem, and now is working as expected. Thank You very much!

Amazing stuff, love the clock!

[@BrianLough]

Thank you Micah! Would love to hear how you get on if you do!

[@Chickey]

Cracking project, shall have to try it on my matrix display as it needs some use.

[@RetroBuiltGames]

Built one, and it's really a novel idea. Love it. Brian, the code doesn't support 32x16 matrices even though there are comment-out options to enable these? I see a lot of positioning and sprite sizes are hard coded for 64x32 sized matrix correct?

[@MarcoOchse]

This is awesome. Will be the first Maker project I will be doing with my daughter (hint: she loves Tetris 😃).

[@EmilePolka]

already tried this, works great, as long as the matrix is 64x32 and based on HUB75 it should work on any pitch models, already tried it with P2, P3, P4 and P6

[@andymouse]

Very nice work Brian, I had no idea this animation existed, definitely a lot of fun. How about another mode? Tip on its side and its playable ?

[@n13ldo]

Ordered a D1 from your Tindie. I bought a ProjectMC2 from Amazon (£20) yonks ago after seeing BigClive tearing one down.

[@BrianLough]

Cool, if your in the UK your order came in literally just in time as my wife was just about to head to the post office! Is that the pixel purse? I know for sure it works with them as somebody has tested it before, but you will need to solder to the unpopulated connector of the purse and possibly solder to the power connector too. I'll try update the instructions page of my website with some more info about it

[@muserbellamy1140]

Morning Brian just wondered if you had thoughts of the 32x16 panel problem 64x32 ok

[@SCAPE0GOAT]

I love this project ! I've never used or built with any Arduino type device or coded them. Would this be a good project for an experienced electronics builder with no Arduino experience ? Any advice would be great. Great videos though. Spot on 👍

[@MsJhgb]

Looks great. Great thumbnail

[@embeddeddevzone5605]

Hi. How can it work with P5 panel ?? Thank you

[@MaxintRD]

What's not to like? Blinkenlights, internet and a TinyPico. Great breakout board. Well done! I'm looking forward to try this Tetris library on my 24 x 16 matrix. Sounds like it's easy to use and very flexible but my display might be too small. (Still curious to know why the ESP8266 crashes. My experience is that it needs plenty of RAM available (>25K) or it may become unstable (depending on what libraries you use).

[@umiturgutaswwsa]

Can't we use nodemcuv3 instead of esp32?

[@kprasann1979]

Beautiful, thanks for the code! It came out very nice.But sometimes, I get a flicker on top right few LEDs and middle row LEDs, though not in full brighness, just a bit to distract you. Any help with this ? Thank you once again!

[@kprasann1979]

Just an update, got it sorted as my supply was underpowered...3a for the display and usb supply from laptop for the esp32, after parallel supplying from led supply to esp32, no flickering. Thanks for the awesome code, looks beautiful!

Tried to built the Titris clock. using your ESP32 Matrix Shield (Mini 32) - Kit, loaded all libaries and imaged loaded fine without no errors but the Led matrix is not working. Any tips? Thanks AJ

[@Grimm93]

Hello Unfortunately I have a problem. First of all, thank you for the great video and your work. I ordered an ESP32 D1 mini, your board and a 64x32 display. Can upload the sketch but the display stays black. Can someone help me here? Can upload examples and they work, but unfortunately the time doesn't😬 Would be grateful to you.

[@WagonLoads]

This looks nice.. Will the Tetris code work on a TTGO T-Display?

[@BrianLough]

If there is a library for the display that uses adafruit gfx if would be possible for sure!

[@MPElectronique]

It would be cool to download a jpeg from inet with Esp32 and display it on the matrix... I saw the spotify display on a 64x64 but the jpeg didnt came out great. An idea? Thanks.

[@TechnoWit3D]

Hi Brian. Do you know how to make KZbin live stream viewer counter using esp8266?

[@sekerbaba2631]

Hallo super Project.. ich habe eine Frage, ich kann im sketch die Parameter nicht erkennen. #define P_LAT 16 #define P_A 5 #define P_B 4 #define P_C 15 #define P_D 12 #define P_OE 2 ist es möglich die parameter in deinem sketch hier aufschreiben. mit dieser einstellung funktioniert es bei mir nicht. Danke im Voraus

[@PapLab]

Beautiful project! I would love to replicate it :) If I understood well, the minimum hardware needed is - matrix panel - esp32 mini - power adapter Is this correct?

[@BrianLough]

Yup! You'll also need some longer style Dupont cables because you need to connect from one connector to the other. Wiring diagram is on the project GitHub page. It definitely doesn't need 8amps, but I don't really just the rating on cheap power supplies! I'd say the displays in general probably need 4 amps , this project needs a little less because it's not setting the colours to white often Will be writing up an instructables for it shortly.

[@PapLab]

@@BrianLough Thank you for your reply! Parts will need some time to arrive from China, so I can wait for your Instructables too (I'm not an expert with programming but I'm very good to follow instructions!).

If it's the pxMatrix version you can yes, you can just change the values that are passed to the constructor near the top

Maybe you can help me with a problem I'm having with mine I'm running the tiny pico with the display you suggested when it's running all I have is the first four rows are working the next four are not working. The next four are, the next four are not working etc. I have 4 displays and it doing the same on any of them I try I'm not sure where to go from here. or what to change in the code I have watched your other videos on RGB led matrix how to get started etc but not having any luck Thank You for any help

I have a Adafruit panel which the R1 pin top left so with the the 2dom wiring it doesn’t require pin B ? I reset device and have a ok in serial monitor still no light

[@damianpinnington5477]

I made this with a devkitv1 module and it works great, but you need to change the display.begin() about 2/3 through the code. I don't think it was mentioned at all. I used my bench power supply and it never goes above 250mA, so if you only want a Tetrix Matrix clock you could power from usb.

[@vectorautomationsystems]

Hi everyone. This project is not compiling/has errors on Arduino 1.8.13. Any pointers? Links to a forum where this problem can/has been discussed and where error messages can be shared?

do you have the libraries installed? and the right board picked? I too wish we had a forum cause i have a different issue with a 64x64 panel not displaying properly.

[@harriebosgraaf2977]

Beautiful clock. But can`t get it to work! Could someone help me understand what i`m doing wrong? I have wired it like it is mentioned on the github page. I have tested it with the pixeltime sketch. Works like a charm. But if i load the tetris sketch, the display won`t light up. First i tried it with the d1 esp32, just like the one used in the example. I use a p4 matrix. I don`t have to use the e pin, so i changed the sketch into ( PxMATRIX display(64,32,P_LAT, P_OE,P_A,P_B,P_C,P_D); ) The pinout is ( #define P_LAT 22 #define P_A 19 #define P_B 23 #define P_C 18 #define P_D 5 #define P_E 15 //#define P_OE 26 //TinyPICO //#define P_OE 21 //Huzzah32 #define P_OE 2 // Generic ESP32 The matrix doesn`t light up. With the pixeltime sketch it does, but not with the tetris sketch! Than i tried it with an esp8266. It starts, it connects. Shows brian lough, than it goes black and does it again. So the screen works. But not with the esp32. What am i doing wrong?. In the monitor you can see it connects to the network and gets the time, but it won`t light the matrix? Please some help??? I would like this clock to work. The dancing banana, the mario and all the other examples work! But not this clock. Greetz Harrie
