Flowcode Support Board

Hi,
When using the PIC16F15324 the FC target options for HF internal oscillator are 1MHz and 32MHz.
Under 'other options' is the clock speed setting which defines FC timings. This only allows a max value of 20.
Could this be changed to allow for the 32MHz timings.
My Flash test is running around 300ms when it should be near 500ms.

Side question, Are low interal clock frequencies considered more 'stable' or less prone to issues in noisy enviroments.
I'm guessing not significantly and as such there is nothing to be gained from the other Oscillator settings in the HFFREQ register. 16,8,4,2 MHz.
So just stick with 32Mhz for general purpose work.
Cheers, J.

Hi J
What you may or may not know is the IntOsc component can be used to generate the required C code to set the internal osc frequency.
The options are: After selecting the options, it displays the C code to enter within a C code block: Also, note that you need to manually enter 32 within clock speed rather than using the dropdown.

The reason for the other options is the lower the frequency the less power the microcontroller uses.
So the lower frequencies are more suited to battery power devices.
In addition, the lower the frequency the more it's suited to selecting lower timer interrupt and PWM frequencies.
