#59543 - Is it analogue? Responding to: ???'s previous message |
So we're still talking about this:
http://www.8052.com/forum/rea...&top=59536 Clearly your uC output is digital, but what about the ISD chip? If the ISD output is also digital (eg, PWM), then surely all you need is a simple logic gate? Maybe also a transistor to get enough power to the speaker? |
