The support is by far the best I've ever experienced. I'm sure you could go to the forum and get the info. (if any change is needed) because pic and stamp goes back and forth fairly easily. Try the demo, it will probably do what you need. (stamp brains are smaller?) HTH cwaugs

If you're going to buy, wouldn't buy anything else but PicBasic or PicBasicPro from Melabs. Hands down the best support forum by far! Well worth the money. Stay away from Mbasic. Not Good!

long post sorry

Well, after at least 6-8 hours of scope time setting at the table (while life goes by) I finally get a small snippet to do kind of what I'm trying to do, and partially understand what is happening as in setting the Ocr1al and Ocr1ah to "pre-fill" the register at the bottom then set the "top" to adju...

Thinking. Be back as soon as I have time to put it into code and squirt it into a chip. Again, I thank you.:)

No no a/c motor. I'm pulsing the output into a coil. Yes, using the hardware PWM's Need to be able to vary it from 56KHz to 61KHz by 1KHz steps. Using the prescalers is too huge of a step though. I'll look into PPM. Thanks much Emmett

HPWM 1,127,1000 is the command in PicBasicPro that allows code to control the HPWM Channel,Dutycycle,Frequency on a 16F877. The duty cycle and channel are easy but I have yet to understand what would do the same thing on a Atmel Mega88 when it comes to frequency. I can handle the rest of the code in...

It's slowly but finally starting to soak in. I need to squirt the latest code I piled, onto the chip, and stick a scope on it and actually see what is coming out of it. Thank you again for your time Sir!

Still researching the accuracy that the timer frequency resolution can be set to and varied from. What i'm not understanding is how to change the freq from 10khz to 10.5khz with the same oscillator. there HAS to be a way. I HAVE to be overlooking something obvious. My understanding so far is that ti...

Hands down, the best PIC group is MELabs as far as killer support on PicBasicPro. Blew me away. HTH Emmett

I think I have a test program, running all three timers, in Bascom. Seems to do what is needed in the simulator anyhow. Tried loading it on a 48 last night but It's different than what I'm used to in PBP. Need to get some more time hopefully this weekend. I'll be back. Ordering a book on "C".

Good information Colin, As to what I am trying to design, Basically the heart of it, (around which I believe I can figure out the other minor details) is a ATMega48, running three frequencies, multiples of each other, I.E. 1-1Khz/2-4Khz/4-8Khz in an a/c shaped square wave centered on top of each oth...

Ah, OK. Is that a big difference as far as processor usage goes? And is that the main advantage?

So you would recommend interrupts over gosubs? Both return to the same section of code they left correct? What book would you recommend to give a beginner some uselul "C" basics? Thank You Much. Emmett

What is the difference between a goto or gosub statement, and an interrupt?
