Hello people, I'm new!
After eyeing the teensy for audio projects for some time, I came across a project the other day that made me decide to take the plunge and order a teensy 4.0 / smart matrix shield / RGB LED panel (hub75)
The project is here:
https://www.creativeapplications.ne...-matrix-display-tutorial-document-1-workshop/
and describes the use of processing to send screen data to a teensy 3.x / smartmatrix shield for 3.x. It gives code examples on both the processing and arduino code side of things, which I understand reasonably clearly (I'm experienced in processing-ish) however electronics and physical computing I'm completely new to.
I presume data is sent from processing to teensy via serial (could be wrong) but I'm not sure how one does that, the link does not describe the physical connections. More importantly I'm wondering whether (with the minimal changes to code required) whether the same combo but using teensy 4.0 / matrix shield for 4.x is capable of the same kind of communication. Ive held off ordering the £150 worth of equipment for fear that I won't actually be able to drive the shield or panel from processing, due to not understanding the way the two communicate and any possible differences that may stop a 4.x doing the same thing they're doing with the 3.x
I could go with t3. X and the previous version shield, however given the superior power of the newer teensy (and that I'm aiming to also use the board for intensive audio applications) I'd rather verify that I can indeed use the 4.x and buy all the stuff pertaining to that generation of board.
This is possible right? Any big issues I should be aware of? How are processing and the teensy connected in either case? I could use Windows 10 or raspberry pi 3b+ (ideally raspberry pi)
I've searched the smartmatrix community forums but find no answer and thought maybe it's more sensible to sniff around here instead. Sorry for length of the post, and doubly so if this information is obvious or easily found (I've read so much my eyes hurt already)
On a further note (though this is not teensy related) there is a Hat for the raspberry pi which uses the same arduino library, is it possible to run processing on the pi and have it transmit the canvas directly (via the smartmatrix hat) to the LED panel, bypassing teensy altogether? Just curious, I'm still more interested in using teensy given my interest in the audio hardware side of things, but if anyone knows about the pi driving these HUB75 panels using the smart LED / smart matrix library then please chip in, I'd be happy to learn.
Yeah, let me know if I can go ahead and order the teensy 4, shield for 4.x and panel without having to worry! (using processing to generate the imagery is a must for me.) And what kind of cabling I'd need to do between the processing host and the teensy board.
Many thanks in advance, and I'll look forward to perusing the forums and getting to know some of you. Cheers!
