Re: Using MOD function

Hello, On 8-bit PIC the floating point calculations are done using functions. It looks like these functions are being referenced from the main program loop and again from the interrupt.

The Flowcode v7 compiler is simply letting you know more about what it is doing. The new compiler is made by Microchip and so is more able to provide helpful and up to ...
