Teensy 4.0

[lovettchris]

Can you add support for Teensy 4.0 ?

When I try and compile your BasicTest example for Teensy 4.0 I get this error:

OctoWS2811.cpp:85:2: error: 'GPIOD_PCOR' was not declared in this scope

[BarakChamo]

I experienced the same issue, the Teensy 4 board definitions don't contain the // General-Purpose Input/Output (GPIO) in kinetis.h or anywhere else, it's only present under teensy3

[egapevets2]

I would also appreciate Teensy 4.0 support

There is an update for teensy 4 three days ago by Paul. I guess you can set the pins in pinlist? I thought below code would perhaps do the trick: const int config = WS2811_GRB | WS2811_800kHz; uint8_t numPins = 16; uint8_t pinList[] = {1,0,24,25,19,18,14,15,17,16,22,23,20,21,26,27}; OctoWS2811 leds(ledsPerStrip, displayMemory, drawingMemory, config, numPins, pinList);

but compiler says:

no matching function for call to 'OctoWS2811::OctoWS2811(const int&, int [360], int [360], const int&, uint8_t&, uint8_t [16])'

[PaulStoffregen]

Yes

[GvBon]

ah nice! the error is a problem on my side then? (very well possible)

[PaulStoffregen]

I just compiled this without any errors.

const int ledsPerStrip = 240;

DMAMEM int displayMemory[ledsPerStrip*6];
int drawingMemory[ledsPerStrip*6];

const int config = WS2811_GRB | WS2811_800kHz;

uint8_t pins[5] = {2, 3, 4, 5, 6};

OctoWS2811 leds(ledsPerStrip, displayMemory, drawingMemory, config, 5, pins);

In File > Prefs, turn on verbose output. Then look for info about the folder Arduino is actually using for the library. Maybe it's not using the copy you've installed?

Or wait a few days... soon we'll begin beta testing 1.52. Then you can just run the installer to get the latest version of the library.

Thanks! Cheers to Teensy 4.0!

Hmm, tried that. Library now is the right one. But still running into errors: `C:\Users\gijsv\OneDrive\Documents\Arduino\libraries\OctoWS2811-master\OctoWS2811_imxrt.cpp: In member function 'void OctoWS2811::begin()':

Oh, yeah, the new code depends on updates that were recently made to the core library.

Probably simplest to just wait for a 1.52-beta1 installer that puts every file in the right place.

[PaulStoffregen]

1.52-beta1 installers are now available.

More than 8 strips do not run (the first 8 do, after 8 they do not, possibly because this is OCTO -> 8 (?)).

Please post on the forum. Show the complete program you're using.

possibly because this is OCTO -> 8 (?)).

Internally the Teensy 4.0 code is using 128 bits (not only 8), so it can support any combination of all digital pins.
