I am doing a project with bi-color led matrix 8x8 and MAX7219 as the LED driver. I want to implement a fading effect on the LEDs, like mixing the two colors by varying the individual duty cycles.
My idea is the use of the
Iset parameter; I would connect the PWM pin from Arduino through the
Rset resistor and feed that into the Iset of the MAX7129 instead of 5V supply. Please suggest whether or not this is possible, if not what can be the alternative approach?
