capacitors) as recommended by the official hardware datasheet. 3. Simulating the Tone Inputs
Once the library files are installed, you can build your simulation schematic. mt8870 proteus lib 35
Observe the output LEDs. For key '1', the binary output Q4-Q1 should read 0001 . For key '9', it should read 1001 . Troubleshooting Common Simulation Issues mt8870 proteus lib 35
: Ensure your digital output pins (Q1-Q4) are not accidentally shorted directly to power rails or other output pins. mt8870 proteus lib 35
