| [SOLVED] Software SPI with PIC18F65K80 |

I have a problem with software spi.
I am using PIC18K65K80
CCS compiler version 5.062
here is my code

I see nothing on PIN_E0, PIN_E1,PIN_E2 on my scope, any suggestion ?

You might not see it on your scope because you're using a slow repetition
rate in your while() loop. Try this program which has a much faster loop
speed: | Code: |
#include <18F65K80.h>
#device adc=8
#FUSES PLLEN,VREGSLEEP,SOSC_DIG,NOXINST,INTRC_IO,NOFCMEN,NOIESO //1
#FUSES PUT,NOBROWNOUT,WDT1024,NOWDT //2
#FUSES CANE,MSSPMSK7,NOMCLR //3
#FUSES NOSTVREN,BBSIZ2K,NODEBUG //4
#FUSES PROTECT,NOCPB,NOCPD //5
#FUSES NOWRT,NOWRTC,NOWRTB,NOWRTD, //6
#FUSES NOEBTR,NOEBTRB //7
#use delay(clock=64Mhz)
#use spi(MASTER,FORCE_SW,MODE=0,BAUD=100000,DO=PIN_E0,CLK=PIN_E1, ENABLE=PIN_E2, BITS=16,STREAM=myspi)
void main(void)
{
while(TRUE)
{
spi_xfer(myspi, 0x5555, 16);
delay_us(200);
}

You're right my loop was too slow,
Many Thanks, problem solved.
