Code:
So to configure the PLL I tried to write just after
;------------------------------------------------------------------------------
; User specific entry code go here, see also user exit code section at end of file
;------------------------------------------------------------------------------
CLKDIVbits.PLLPRE = 0;
PLLFBDbits.PLLDIV = 30;
CLKDIVbits.PLLPOST = 0;
and also
CLKDIV.PLLPRE = 0;
PLLFBD.PLLDIV = 30;
CLKDIV.PLLPOST = 0;
and also
CLKDIV = 0;
PLLFBD = 0x001E;
and also just after .ifdef HAS_PPS same as aboveWhat is good writing?
for PPS I had configured like this:
U1RX -> RPINR18 -> RP10 = 10
RPINR18bits.U1RXR = 10; //U1RX RB10/RP10
RP11 on RPOR5 -> U1TX = 3
RPOR5bits.RP11R = 3; //U1TX RB11/RP11
For information ... This configuration will work for my current program
Code:
