I'm just trying to test the SOUND command with a 16F690. Unfortunately, I'm not getting any sound, but I'm pretty sure it's not on the sofware side of things, but the hardware side. The PICBASIC compiler manual shows a capacitor in series with a speaker. I input an alternating tone with the sound command where it should alternate tone/silence/tone/silence and I hear a faint "clicking" sound so I think it's trying to work.

Does anyone have experience with more specifics as to the speaker/capacitor arrangement that would work.

I also tried to directly drive a piezo element I had in an old parts bin, but that didn't work either.

TIA
