fast approximate algorithm of phase for complex number

Hello everyone!I am using dsPIC33CK64MP506 MCU, XC16 compiler v1.41.I want to get feature data of a fractcomplex-type data, which are its magnitude and phase.I found build-in functions "_Q15sqrt"&"_Q15atanYByX" in <libq.h>, but it turns out "_Q15atanYByX" takes too much time to get the result fo..

XC16 Linker Bug with Boot Sector and AIVT, dspic33ch

I'm experiencing a problem with the XC16 linker which I believe is a bug. The linker refuses to allocate most of the entries for the alternate interrupt vector table, as well as other small manual allocations with no discernable pattern. For those not familiar, the address of the AIVT in program mem..

dsPIC33CH how to configure the ADC?

I've found DS70005213G so I'll try to figure it out for myself but the configuration options in MCC appear to make no sense at all, I have a choice of:AUX VCO DIVMUXFOSCFOSC/2PLL VCO/4 Now since the PLL is running at 1200MHz VCO/4 ought to be 300MHz, and I believe I probably need 50MHz (Tcy 20ns) to..

dsPIC33CH valid slave PLL setting solved!

TLDR: I hadn't enabled the slave PLL mode in the master project, since all the other PLL settings were located in the slave project and it wasn't obvious that I needed to. Having updated it things work as expected. OK so I improvised something that should flash a LED once per second. Running from th..

__resetALT

Dear all, I wrote my own bootloader for PIC24FJ256GA106 project using MPLAB-X 5.35 and XC16 toolchain 1.50It works, it loads the user program in flash and jumps to the correct entry point location.Of coures I have to call __resetALT (user program doesn't inizialize memory befor jumps to main())but t..
