Hello Brad
Super pixel bros is an amazing system game 8x8 RGB and i saw video about it
i'm just asking my self why you did not use one Integrated circuit instead of three(74373) to drive the 8x8 Rgb Matrix LED
The way that i'm thinking for this one because we can reduce the part list, for example if we use TLC5947 from Texas Instruments(24-Channel, 12-Bit PWM LED Driver with Internal Oscillator) 4096 steps for pwm this not bad it's very nice i think the current version of hardware SPB can get 256 Steps Pwm?
With this IC we can limit the current with ONE external resistor it will be usefull because we will not use a resistor for each led in the matrix it's amazing One external resistor Against 24 x 150 Ohm Surface Mount Resistors !!!
So Brad what do you think about this?
