Instead of hunting for a broken MT8870 model, design the circuit with an Arduino. Use the ArduinoISP or VIRTUAL TERMINAL to simulate decoding. mt8870 proteus lib 35
: Saves time by verifying logic and 4-bit output before building physical prototypes. Imperfect Simulation (Q1, Q2, Q3, Q4) corresponding to 16 different
: Allows you to see real-time output (hexadecimal or binary) on virtual terminals or LEDs during simulation. Version Sensitivity mt8870 proteus lib 35
