Is the "GreatCowBasic" Projekt death?

hello FatBob

i follow your project, my question is, how to make frequency manual adjust with potensiometer

Connect pot to an ADC input on the PIC. Read the ADC every so many cycles and then use ADC value to adjust the Timer value that sets the PPS rate.
Look at the code I posted in the "My take on the HH2" thread, post #14 for code that adjusts PPS rate with a pot.

In Bob's code Timer1 value sets the PPS rate so this is the value to adjust with a pot/ADC reading.

Hello Waltr,

Many Thank, i will try your code

Careful!
My code uses different PIC pins than Bob's PIC so will not work if you just Flash the PIC in Fatbob's HH.

Do try my code in the MPLAB Simulator to learn how it works. The code in post #14 also has GEB. Read the comments in the code.

Good luck and have fun.

So with the Ground balance added in we get positive responses to lower TC signals and
negative responses to larger TC's with a hole where the ground TC occurs.

To hear those signals we need a dual tone or dual VCO. Here's an attempt at a dual VCO;

Here's a Dual Tone one;

This might be easier to do on a full size HammerHead so I'll use this one for now;

Hello
Dear FatBob
Is it possible to guide me how to use your dual Tone (CD4046)?
Can you tell me when we should use the two 100K pot (TL072)?
Thanks
