IoT RGB LED Matrix Controller (ESP32)

Previously I used the smartmatrix library with arduino code. After some research I found no included function, or library to drive my display with Espruino. The article about writing my own C extension kept me thinking about a wrapper for the smartmatrix library. Finally, I successfully added my own module into the Espruino code. But here is my problem: The smartmatrix library needs the Arduino.

Hello Jonas user and thank you for your interest in Espruino! A simple title edit may draw a more specialized respondant. There are a few projects with minor modifications that may do what you need, without the overhead of the path currently on.

Have these links been checked out? Yes you are right with the headline. I also checked out this projects bevor. You can drive this led matrixes directly by the board each led individually.

I have a 64x64 matix 4. JonaswinzI'm now curious what role Espruino plays in that scenario? I expect some parts use actual Espruino components With all these scanning drivers, flickering or smooth, continuous change are the issues, because you have to feed the data between scan lines have to be put out. Espruino has a Graphics class with which you can create content into a buffer. From that buffer you have to get the data out onto he panel.

This Graphics reference link class is implemented natively - in the Espruino firmware in C - to secure speed, and has many options on creation to store the data suitable for simple pumping out. You may not even need to do a specific build Using an ESP32, you most likely need to do something for compiling the inline c compiling for the upload before the upload for the application that you write in JavaScript.Users browsing this forum: Baidu [Spider]Google [Bot] and 38 guests.

Skip to content. I poured over the board with a good quality magnifying glass and couldn't eyeball anything. Does your LED respond "appropriately"? I almost can't imagine it, but there may be something wrong with it.

Just wanting to make sure before we blame the hardware. When only GPIO 0 is on, red and green are shown.

I am happy to perform any other diagnostics desired or otherwise show information screen share etc etc. Here is a link to a high def picture of my board. I did add three jumpers: 1. USB power jumper 2. RX-RX jumper 3. TX-TX jumper these appear to be required as per the Espressif getting started guide.

Kolban earlier. That's not what's on the board! Putting my hardware engineer hat on, I think' that's a smart decision, I personally applaud this implementation, I just wish I'd had the schematic before starting to fool around with the RGB, it would have saved me some time. Which OS and which terminal program do you use to connect to the board? Is there any difference in behaviour between connecting the board to a computer or to a USB charger? Jump to.

This: Full story and build I inherited 64 strips of mostly 64 neopixels per strip some were as low as 61, and some as high as I decided very early to remove the IP67 protection as the silicon is resitant to virtually all glues, making it very hard to work with.

I also had to splice broken LEDs in the strips I inherited, so it's much easier to do without the protective casing. What I did was connect power from each of them at the end and therefore spread the maxium 10A they can draw to 4 times 2.

The green wire goes between the Data Out to Data In pins of the strips 3 short green wires only for 4 strips The 64x64 array was meant to be 2 arrays of 32x64 for ease of transport, each with their own 60A 5V power supply when actually 40A would have been enough for each set of LEDs even if their maximum is around 80A in theory. They don't like staying together due to size and thermal issues.

So, my shirt that drives 24x32 uses ESP ESP can do up to 4 lines of parallel output, which is not sufficient for a proper frame rate on pixels. ESP32 does allow up to 24 lines of parallel output untested and can easily do 16 lines of output frames per second for pixels. Teensy would would have worked too, but I've had too many problems with teensy, namely: the hacked up build environment patched on top of some version of the arduino sdk.

Recently I've had 30 second pauses before compiles even happen if I'm using the serial port reported the bug, never heard back, never got fixed. This made sense years ago, but not anymore today that arduino supports other hardware boards "the right way" newer sdk patch that's supposed to fix things, working even less for me 1. This was a big deal for me, I reported it, but never got a fix.

Now, I'll have to admit that SPIFFS starts falling in performance due to how it's written when you reach 1MB or more of data, but it could be fixed with a better driver and beats no onboard filesystem at all on teensy you need the ish dollar teensy 3. It pains me to say this, because Paul Stoffregen does an incredible amount of work for one person, but he remains one person with a closed bootloader design and a hacked up SDK sorry to say it.

This is not to say that Teensy 3. Why not use those premade 32x32, 32x64, or even 64x64 RGBpanels? This is a very good question.

First, they don't exist for neopixels, they exist for a different lower tech solution that requires a lot of work to drive. Sadly, because they require row scanning like an old CRT TVthey also don't look good if you move them, move your head, or take a picture unless you drive them at very high speed, which is harder to do with microcontrollers.

If you want to go higher sizes with those RGB panels, it gets more complicated as you need to drive them even faster. An ESP32 can reasonably drive up to 96x64 pixels while a tensy 3. You need a raspberry pi or an FPGA for bigger matrices. My point here is that neopixels cost more, but they're a lot easier to drive, despite the timing issues you start running into when you're driving a lot the more you drive per line, the lower the refresh rate, putting a reasonable limit for a single MCU around 10, LEDs if you're ok with a 35Hz refresh rate.

I personally wish for Neopixel matrices that ship in 32x32 or higher, potentially with the option to inject a new data line every or pixels so you can drive them as one big slower array, or cut the data line in the middle and inject parallel data lines for faster refresh rates.

ESP32 8 or 16 Parallel output and driver First, pixels without parallel output, I would only get 7fps, which is quite slow. This can be used for more than 8 pins, I used it with 16 and the driver can switch RMT back and forth between the first set of 8 pins and the 2nd set of 8 pins.

Also, in my testing, it did not work reliably until I added level shifters, while Sam's driver actually produced better waveforms that worked at 3. I'd say it depends but if you are ok with up to 8 parallel pins, use Sam's driver with RMT, and if you want more pins up to about 24use Yves' driver.

This was doubly a mistake because there is sadly no standard pin numbers between ESP32 boards, meaning that I had to re-wire my plugs if I changed chips: My other problem was that while 3. I had to add level shifters, which also nicely added a level of indirection between my cat5 twisted pair cables and the pin numbers on the chip: Later, I changed one more thing which was to reomve the bidirectional level shifters that were unnecessary and caused issues at boot on ESP32 by messing with some IO pins.

I then did a recording of the entire set of demos, including 64x64 animated gifs I found and liked, and ended up with 41mn: Conclusions The build was a lot of work, no fun at all: over 4 days of solid work If you do this, strongly consider getting pre-built matrices that are ideally at least 32x It's not trivial work either if you re-inject power in them in more than one place, but clearly less work than laying 64 strips by hand like I did.

The colorful light is jewelry, dotted on her dress. Each LED can be independently addressed and controlled. What's more, it is a high brightness, long life, no pollution, pure color LED display module. It can be used both indoor and outdoor, safety and stability, the module can not be mutually extrusion deformation, also can be used normally in harsh environment.

I hope you will learn as much as me! They were kind enough to let me play with some LEDs. This thing will need a good power supply. I will test things out first and see how I can wire things up.

I used the existing adhesive to glue the strips to the piece of wood. This should be good enough for the testing. I will see how comfortable I am with writing a code for this, then decide what would be my final project. To build this matrix I cut the strips to 41 LEDs per line. I have the total of 10 lines. Each new line has an opposite direction. To drive the WSB correctly, you have to check what direction the strip should be facing.

Basically, I have created one very long snake. To learn how to drive WSB read this. To power it all up I needed a power supply. I picked a 5V 30A switching power supply. My napkin math tells me this is more than plenty to get each individual LED powered up. This thing looks beefy! Initially, I connected the power supply at the beginning of the strip to figure out how many LEDs I could power before the voltage collapses.

The answer is 40 depending on brightness. Increasing the voltage could work, but remember, these are individually addressable LEDs, therefore, you are risking a damage to it, if you drive bigger than 5V voltage, but turn on only a few LEDs. As you can see, up to about 50 LEDs we have no issues at all.
