OK, sorry to miss the sublties of your code. Clearly one has to not only RTFM, but read what is NOT in the FM.
Taking on board your observations re spi_xfer() vs spi_write(), out of curiosi ...

@guageguy
Here you go:
#include <18F16Q41.h>

#fuses NOWDT
#use delay(clock=16M)
#include <stdlib.h>

#pin_select SDO2=PIN_A2 // chip pin 17
#pin_select SDI2=PIN_B4
#pin_select S ...

@temtronic: RTFM is always good advice, but in this case the FM was in conflict with the compiler. Having read the manual and the help file I reached the conclusion that if I stayed with the hardware ...

Thanks for the advice,

I replaced the #use spi line with
#use spi(MODE=0, BITS=8, CLK=PIN_B6, DI=PIN_B4, DO=PIN_A2)
// chip pin 11 13 ...

Using Workshop compiler v5.105 on Windows 10
Several attempts to use SPI have failed,what am I doing wrong?

Latest code in entirety:
#include <18F16Q41.h>

#fuses NOWDT
#use delay(clock= ...

Good advice, as always.

Thanks Alan, your code looks like what I am trying to achieve, but I could not get it to work. I also studied the CCS ex_macro.c, but that didnt work either. So I guess I am going to have to set up si ...

Thanks both, I'll just write separate functions for each.

I have a need for six UARTs on a single PIC16LF15325. Only the transmit lines are needed and I have written a simple function to take a byte and send it from a pin specified within the code.
Rather t ...

Thanks for the additional material. Like you I nearly always have the help file open. At 78 years old, it's even easier to forget.

Thanks temtronic, that worked perfectly.

"Why not use the make() function that CCS supplies ?"
because I didnt know it existed, nor did I expect it to exist!

I receive an int32 as four int8 and I need to reconstruct the original int32

e.g. Byte3 = 32, byte2 4, byte1 = 8 and byte0 =99

longInt = (Byte3<<24) gives the correct value of 536870912 b ...

SOLVED
A previous SPI setup had not been deleted.

Attempting to set up an SPI facility on 16LF15325 using statement
#use spi(MASTER, DI = PIN_C0, DO = PIN_C1, CLK = PIN_C2, FORCE_SW, BITS = 8)

followed by: spi_xfer(0xF8);

I note that DO in #us ...

Thanks for such a rapid reply.

Edit: My Bad- the chip is 20 pins, need more coffee.
