Thank you for your advices. I did a mistake in my comment, but everything was right in the code. I have then implemented the Hold pin, that I didn't before !

I have switched to C18 as I already mad ...

Thank you for your suggestion.
I have used read_spi as well, but I remember from another project that there are troubles in CCS library while reading or writing (I don't remember which as there is al ...

Hello, I have switched to a PIC 18F2620 which has UART and SPI pins separated, and I am now on C18 compiler.. which doesn't change much.. I have exactly the same problem, (except that my UART is ok no ...

First of all, thank you very much for your help

- Post your compiler version number. Some versions have known problems.
- What are the voltages used for your processor and for the flash memory? Th ...

I have just checked with a scope where the problem could come from.

#HOLD is high
#WP is high
SCLK is ok
SI is ok
#CE goes down when I send or read something and high afterwards
SO does not s ...

A few more notes:
1) The call to malloc uses a variable 'length' which is uninitialized.
2) Use of malloc in an embedded application is not recommended because memory fragmentation could cause probl ...

Hello,

I've been looking around to find any sample code to compare with what I am doing, but I couldn't find anything that solved my problem. I am simply trying to read the status register of the m ...

Hello Eduardo, as I implemented you files and built my project, i got some buildings errors on your nRF24L01P.C

That's great thank you very much

Thank you very much Eduardo for your library, I will manage to use it but I need one more explication. When you say "it will asks you for the pins. " You mean I should set the pin, but where ...

well, I managed to understand that what was wrong was the fact that this library uses variable names that are reserved (such as byte)... I'll have a closer look at Eduardo's library much more recent a ...

Hello,
I'm trying to get my nRF24L01+ board working with 2 Pic 18LF2550. Thank's to Brennen's library I managed to understand how it works but I am facing some building's errors as I modified some mi ...

The best way not to get confused is to use spi_read() for both read AND write and use the return value if needed... avoiding spi_write

Thank you very much for your explanation, it's clear now.

It is great it works the way I want. The weird thing is that If I write
spi_write() it writes only, and spi_read() writes and reads.. why is there a read then...
