sougata,
Do you have any example code of this application? It sounds like something I would like to try but ASM interrupts are over my head...I haven't gotten the whole interrupt concept down...

Norm,
Thanks for the advice on the SPI setups...I'm back home from a long trip and will be sitting down to look at this in detail.

Jerry,
I am way past the point where I can say I'd be...

Norm,
Great project. I think I read about it last week when I was searching for PIC Audio Projects. Thanks for the link and the additional info. Where did you originally get the info for the...

I'll have to look into this..it sounds interesting but it may keep my PIC busy for longer than I'd want it to be at any given time, especially if I have to monitor the start and end of the audio to...

Hello all,
Just writing to find out if there is any collection of information on SPI commands out there. I am using a PIC16F88 to interface with an ISD1700 Winbond Chipcorder and since SPI is...

Great suggestions. I was thinking about using a digital pot to bias the amplifier...maybe go from a normal bias to overbias to get the distortion... Dunno if that will work as planned or if it's...

Ok, done with my armor...now on to the audio... I've been playing with the PIC but most of the noise that I can get to come out of it are too "digital sounding"...when using the SOUND command. ...

Well, I've been looking at Audio amps... The LM383 would have been perfect but it's obsolete. There is a replacement for it though and I found a few others that I like. Almost finished with my...

Wow, I've been so busy building my armor that I didn't see the topic reply to this post... I've got to sit down and analyze all of the suggestions but DANG you guys ave some great ideas. Not sure...

Adam,
Sorry for the late response, I've been on the go all weekend. I like your ideas and can probably incorporate them into the design initially to help with the design. :) The link to the...

Adam,
Yes I was planning on using an external amp..not sure which one yet but using the A/D comparator sounds like a great idea! The noise I want the PIC to simulate is just static or the short...

Naaw, it's all hands free. The unit has to be in the helmet and there is no way to constantly keep pushing a button...especially when you are talking, holding stuff (blasters) and moving around. ...

Hi all,
I was wondering if anyone had any experience with using a PIC in an audio amplifier circuit where you speak into a microphone and the Audio amp boosts the audio and distorts it a little...

Awesome. That last link with the explanation from Melanie has got to be one of the best writeups I have even seen. I remember her from way back when I first started playing with PICs. It's been a...

Hello,

I've been poking around for the last two weeks trying to find out how to do an arctangent function with the PIC and finally gave up and joined the forum. I am using a PIC16F628 to read the...
