Re: HCMAX7219 - LED driver library
Sorry , I mean the indexes from 32 to 96. It display's everything at the right position. From index 1 to 32 it display's nothing. From 32 to 96 is 64 positions, with is 8 times Max7219, with is the standard number of chips,if I read the manual rigfht, It looks like the buffersize is not expanding to...

Sorry to bother you again but i have one more question.
Is it possible to change the pin numbers fot DIN CLK LOAD as my project is completely wired .
My pinnumbers are DIN 22, LOAD 24 CLK 26.
It will be a great help if it is possible.
Thanks in advange.

Re: HCMAX7219 - LED driver library
How many HCMAX7219 can the LED driver library handle?
I have 12 8x7segment display"s to handle.
The Arduino Led control library can only handle 8 display's on 1 instance.
