    Default Re: Programming RFM radio modules in Basic

    Regarding the comments on the program, i leave them there for me. Sorry for disturbing your reading by using those comments. Because of i use them for my children project GPS, i try to keep those to remind me what i have done.
    there is a big difference between comments that impart some information and visual white noise that masks the very few bits of data that are crucially different
    and worthy of notation
    This is more entertaining than Free to Air TV

    My knowledge and time not helping my self to quickly develop a simple LED to light from one end of RFM69hcw to the other.

    But i will keep reading and studding all the information needed to achieve my goal.

    Now a small step, in the code is to add the DIO0 pin from RFM69HCW to PIC18F26K22.

    As i read from the net, that pin is the:

    Received data ready interrupt signal from RFM69HCW to microcontroller

    TRIS register must also be configured as input at that pin i guess as the RFM69HCW is the one sending data to PIC.

    That i believe will complete the connections between the PIC and the RFM.

    Code:

    As i read from the net, that pin is the:

    Received data ready interrupt signal from RFM69HCW to microcontroller
    not really, in rx mode its PayloadReady in tx mode its PacketSent



    That i believe will complete the connections between the PIC and the RFM.
    that's 1% of the job done


    cannot see any point to creating these vars , they will never be used
    Code:
    SSPIF   VAR     PIR1.3          ' SPI interrupt flag
    SMP     VAR     SSP1STAT.7      ' Data input sample phase
    CKE     VAR     SSP1STAT.6      ' Clock Edge Select bit
    SSPEN   VAR     SSP1CON1.5      ' SSP Enable bit
    CKP     VAR     SSP1CON1.4      ' Clock Polarity Select
