First of all hi everybody.I have recently received 3 MAX7219CNG and decided to start a project with them. at a fast search i found the wiring diagram at arduino.cc . I make all the connections - power from the arduino, load, clock and data, etc. all like in wiring diagram for a single MAX7219. I wrote a short schetch wich should blink a single led, i uploaded and when i power the MAX7219 surprise : all the matrix was HIGH, not just (1,1). I search different schetches, but not working.All i obtain is all leds to high. DataPin,Clock and Load works correctly.I switch the Max IC with a new one . The result was the same - all the matrix was power on.
I don't know what to do...
What should i do, or where is the mistake ?
PS : I am sorry for my bad english
