Behavioural mixed-signal modelMAX7219 8x8 modulemax7219_matrix
LED matrix 8×8 (MAX7219)
Red 8×8 LED matrix with MAX7219 (SPI-like: DIN, CLK, CS/LOAD), up to four modules in a chain (module 0 at the input on the left). In shutdown after power-up – call shutdown(0, false) first. Drive with LedControl.
