I modfied the existing LedControl Library for using the real SPI. I got a problem of my Drivers wich was dasychained. I get some flicker while switching the different LEDS. so i modified to war with the MAX7221 with SPI Library. The will remove the flicker because i changed the shiftout to real SPI. But now i dont know how i bring it up to the playground?
Can i get some little help of you guys?
Theres only one little problem i had to move the two SPI Libray files (SPI.h + SPI.cpp) into my LEDControlSPI folder to use it. If i edit the LED Lib and add the includes with #include <SPI.h> or #include “SPI.h”. I get some error while compiling wich sound like these (No such file in these directory). It only works if i copy the both SPI files in the same folder to get no errors. I attached LEDContorlSPI Lib.
