function that puts a byte of data into a max7219 register function that puts a byte of data to the max7219 function to control max7219 clock line Any ideas to solve this problem or has someone already done a programm, that controlls the brightness of 64 LEDs individually? The programm itself seems to work, but I have performance problems! The on/off frequency of each LED is to slow, although there is no delay function in my programm. there is a function called “brightnessController” which turns an LED “on” or “off”, depending on its value in the array “brightnessArray”.
At the moment I have 8 possible values for the brightness (0…7). In the future I want to controll these values with Processing over the serial port. each byte stands for the brightness of an LED. My idea is to declare an array of 64 bytes. The hardware part is already done and I used the code example I found in the sketchbook “max7219_v1” to work with.
I want to use the max 7219 LED driver to controll the brightness of 64 LEDs individually.
