Re: Testing the piezo speaker


 

Each key press creates a beep as well as turns on the led. If you don’t hear a beep, I would check to see if the opto coupler is installed?correctly.

I finally added the piezo speaker to the Z80MC. It only took me 2 years!
What I'd like to know is how is the speaker accessed?
I half expected there to be a beep or something when the system booted up but I didn't hear anything.
Is there a way I can test the speaker?
Short assembly or basic program maybe?
I looked in the monitor code but I couldn't find anything other than the "beep" LED.
Thanks for the help.
