Thanks Martin. I think you've probably hit the nail on the head. There is an LCD display in the code so I'll start by checking that out first.
... and yes I ought to be more diligent about my use of variables; local against global. Great tips. Much appreciated.

Anyone have any ideas why I getting a compilation size descrepancy between using Flowcode 9 and 10 when selecting a 'Compile to HEX'? Flowcode 10 is creating a HEX file that is 3% larger than Flowcode 9. Flowcode 9, Hex File Size 63,776, 93 per cent of chip size Flowcode 10, Hex File Size 65,600, 96...

Once again Martin. Many thanks for the feedback

Which component DSP Output should be used on the flowcode panel to prepare the output for sending out of a PIC's I2C hardware to an I2C outboard DAC. I need a DSP output icon on the flowcode panel (to finish off the DSP processing), then I plan to read the integer value from that output into a varia...

Just checked it out. There's some great info there. That will really help. Many thanks Martin.

Hello Martin, yes I was meaning the FC_Comp_Source_DSP_Rectifier.fcfx file. Ok that's cleared that up. Can I just get quick verification on your comment "The DSP components allow any microcontroller within reason to run DSP functions." Is the limitation re. the chip, then dependent on how ...

Thanks Martin, that's made it easier to understand. Much appreciated. BTW. FYI I was looking at the DSP Recifier.fcfx example code this evening on the WiKi and that is mis-behaving (no simulation / simulation error) in exactly the same way as the filter example was doing before you fixed it!!! I kno...

Hi Martin Thanks for that. I confirm it now simulates but could you PLEASE just explain what the PWM circuit is doing in this example. I can see the PWM mark space going up and down but I'm not sure how this relates to the pass band filter. I was thinking the demo should show the frequency changing ...

What I don't understand is why when you open the bandpass fcfx file in Flowcode and look at the chip/properties selection; the chip is showing a non Microchip DSP device. How can you run a DSP simulation with a non DSP device? Or does the Flowcode simulation ignore the chip selection and its only ne...

Anyone know why the wiki DSP filter examples aren't running. i.e. fail to simulate? Tried in Flowcode 9 and 10 and both fail. The sim gives multiple errors: Unknown or missing components. I really thought these would work off the bat as they are in the wiki help files designed to give users insight ...
