Particle Photon and a 64x32 pixel RGB Led Matrix panel dont show anything

[RickardPettersson]

Particle Photon and a 64x32 pixel RGB Led Matrix panel dont show anything, the code i running on the photon is below, any ideas what i can do wrong? I have pin everything like in the readme file here on github.:

@RickardPettersson, did you also wire up the RGB pins as indicated in RGBmatrixPanel.cpp:

define R1 D0 // bit 2 = RED 1

define G1 D1 // bit 3 = GREEN 1

define B1 D2 // bit 4 = BLUE 1

define R2 D3 // bit 5 = RED 2

define G2 D4 // bit 6 = GREEN 2

define B2 D5 // bit 7 = BLUE 2

[RickardPettersson]

Yes i did, should the led on the photon on D7 we lightning small?

[RickardPettersson]

After some more looking on what can go wrong i think it is that i has not good enough electric dc adapter so i have buyed some new one 4A i need for the display.

[RickardPettersson]

I Tell you in some days.

@RickardPettersson, great!

Greetings,

Can You give us the full circuit schematic? Other thing, check your GND connections.

[RickardPettersson]

With the settings below i got it to work.

define RGBSHIELDVERSION 3

RGBmatrixPanel matrix(A, B, C, D,CLK, LAT, OE, true, 64); //64x32 panel
