So voltage is 3.3V

after some small issue I check that I can read and write configuration on each.

but still no RX.

I change:
#fuses INTRC_IO
and
output_low(RESET); // reset pin

oups sorry

It's a MRF24JM40A

1) yes I have a flashing led at each send (500 ms)
2) no only the MRF
3) everything running 3.3V
4) The MRF24J40 supports SPI (mode 0,0) which requires that SCK i ...

thanks Ttelmah for this information.

My next step is to make it work a PIC24 (first time I use one)

this is what I try with no succes

I use a Pickit demo board with 18F45K20.

My final goal is the make the software SPI work.
I first try to update setup_SPI to use SPI with SPI hardware Pins.

so with

I try to update it with
#USE SPI (MASTER, MODE=0, BITS=8, DI=PIN_C4, DO=PIN_C5, CLK=PIN_C3, ENABLE=PIN_B1, STREAM=XFER)

and still have the same problem

8Mhz clock.

With

Hi all

I want to port a working code using hardware SPI to another using sofware.

So I first try to use spi_xfer insteed of spi_write with hardware SPI.

I switch from setup spi to use spi

thanks PCM programmer for your time and support.
I will contact ccs.

Hi Jay

Your right living the interrupt enable is not a good idea for my sample prog but it's not the cause of the problem I get.
As I told you I have no build error so I suppose it's a buggy versi ...

Hi Jay

I made no change, if a build a version with 5.50 it works if a build a version 5.59 it doesn't.

on a simple menu like on the example

My program used to scroll through the menu when the up/down keys

do not cause it to scr ...

Hi all

I use this kind of code with older CCS compiler (<5.50) without any issue.
But with latest version 5.59 I get no error but the code is not working any more.

I point out the default a ...

thanks PCM programmer

finally I get work with read_program_memory(mempointer, buffer, 1);
