LED display for Paricle Argon

Tags: #<Tag:0x00007f038c49b150>



I am looking for an led display, similar to this one [https://www.adafruit.com/product/420], compatible with Particle Argon. Any recommendations?


@muneebr1, there is a library for the Photon for those types of display called RGBMatrixPanel. However, it uses a hardware timer library call SparkIntervalTimer which has not been ported to the mesh devices due to hardware differences between the STM32F205 used in the Photon/Electron and the nRF52840 used in the mesh devices. Once the mesh DeviceOS has stabilized and more then one hardware timer is made available, I will be writing a version of SparkIntervalTimer for the mesh devices.


@peekay123 Thanks for the reply, i am fine with using the photon, as long as it works. If i use the photon and buy this display, would it work?


@muneebr1, it will. Be aware that the display is driven by bit-banging code so it only support 512 colours (3 bits per colour). Otherwise, it works very well.


My LED Matrix display running Paul’s clock code is still running perfectly with a Photon.

It’s one of those things that you use multiple times every day of your life.


Do we have any estimate yet when the mesh devices will be developed to that point? I’m waiting for it for a couple of reasons including these hub75 displays. Even a rough baillpark, by summer? In 2019 at all?

I don’t mean rush the particle team, and I’m much more eager for better mesh stability, message reliability, and high available mesh networks which are rightfully higher priority, but are user hardware timers even on the timeline? If it’s going to be too long I’ll probably just buy a feather M4. But even if we’re talking 6 months, I’d rather wait for mesh.


@RWB and @peekay123 Thanks for your replies :slight_smile: Is there any example code i can look at on how to use this library and set up everything up? Thank you again, so much!


@muneebr1, you will find RGBPixelClock in the Web IDE. However, it seems that RGBMatrixPanel is currently a private library. I need to publish it to make it public which I can do later today.
