| With these requirement, it is highly unlikely to accomplish this on a 16F MCU.
You didn't mention how many poles or the passband ripple (Ap) of your Chebyshev filter. A 2Hz Fc and 440Hz Fo requir ... |

| Hello,
I suggest to at least use an 18F MCU. The PIC16F876A doesn't have a hardware multiplier thus making multiplication cumbersome. Where multiplication of IIR filer coefficients, real and ima ... |

| Hi PCM,
Thanks for the reply. So CSS made the change even though it would break code made with 3.249.

| Hello Folks,
Well, I thought I would give 4.025 a try to check the progress. Besides the funny behavior of the GUI it appears there's an issue with pointers using inline asm. V 3.249 incr ... |

The ICD-U40 cannot program the j series processors correctly. It doesn't set the configuration words correctly. In fact, I think they are in the wrong location for this p ... |
