MAX7219 using LED matrix studio

Other Hardware LEDs and Multiplexing
1

hi there!

i am about to give up,

im using MAX7219 cascade 16X16 (total of 1024 led)
and i cant find any template to use for my generated files from the "LED matrix studio"
all the example that i found are for test scroll

below an example of generated animation frame:

the code is been uploaded but the frame is corrupted

I might be wrong, but I belive what you are actually using is the LedControl.h library and if you read that library documentation, you will see that it is written to control only a maximum of 8 Off MAX7219 Matracies.

LedControl lc = LedControl(12, 11, 10, 16); might compile, but it will not control 16 Matracies as one chain, belive me I have tried, until I discovered the limitations of LedControl.

I would look at using the far more extensive and excellent MD_MAX72XX or even better the MD_ PAROLA libraries which should already be available with the Arduino IDE distribution.

Hope that helps.
