    Fundamentally, it looks like "no change". I've printed out the values for all four modes, and then the value of the mode selected. The...

    Hippy, Thanks for your further thoughts. I tried SPIMODE10 and got some odd results - the READs are consistent (albeit wrong), the...

    The results are: Original version (pinMOSI set first) Started PATABLE Write 0F=0,0,15 PATABLE Read 0F=0,0,15 : 0F 0F 0F 0F 0F 0F 0F 0F...

    How do you feel about 2F? Started PATABLE Write 0F=0,0,15 PATABLE Read 2F=0,2,15 : 2F 2F 2F 2F 2F 2F 2F 2F The reason, I think, is...

    Hippy, I used your code with a power-down/up and it worked for SPIMODE00 and not for SPIMODE01. I've gone back to my earlier sample...

    Hippy, Thanks for doing more research. I've been busy on other things so not much time to test. However, I can report that your code...

    Thanks for the thought - it is running 20X2 vC.3

    Hippy, Thanks for spending time on this - much appreciated. In answer to your first point - I have tried two 20x2, with the same...

    Thanks for the info, Hippy. I must be missing something very obvious, but at the moment, I can't even get hspiout to write, let alone...

    Aries replied to the thread spiin versus bit-banging.
    My previous experience of HSPI was not successful, hence my hesitation in using it. You suggested using HSPIOUT and PEEKSFR to get the...

    Here is the datasheet for the CC1101: http://www.ti.com/lit/ds/symlink/cc1101.pdf (although I confess mine came from China). I've put...

    Aries replied to the thread Is Hserin really this slow?.
    I'm not sure that sertxd(w1) would show the characters correctly anyway. b2 = "A" b3 = "B" sertxd(#w1,".") sertxd(w1,".")gives 16961.. -...

    As a postscript - it seems that using MSBPre_H inverts the meaning of SDA, so the result has to be NOTted ... high SCK...

    Thanks for the thoughts - I will experiment a bit further. Meanwhile, a bit of good news: using your idea of "reversing" the clock, I...

    Aries replied to the thread spiin versus bit-banging.
    I'm testing this with a 20X2, although I will probably need a 28X2 in the end (more memory). I have already unrolled the loop in...
