How to configure SPI in PICBASIC PRO?

[Russ Kincaid]

The datasheet says that setting TRISA = 1 sets the port as input. I believe you have it backward.

Noted...
Should be...
TRISA = %11111111 'set PORTA.5 as input.

Thanks...

Ooopss... PORTA.5 should be set as input to enable the SS. Pls correct me if I'm wrong. Thanks.

Hi, moogle,

I have followed your "pilgrimage" through several forums looking for helping to make to work your SPI routines.

I also have verified the little interest that some manufacturers put in helping their clients, for example Microchip and Crownhill, this last is incapable to put a simple example of a Masters and a Slave working in SPI communications.

I have begun to try to start up your routines but they do not work and I do not dare to write in the forums since the answers that they gave you, have been sufficiently frustrating for my.

Well, your routines seem enough to learn a PIC-to-PIC SPI, so, if you have them working, please, put them here in the forum or send me them by mail.

So let me see if I've got this right:

I also have verified the little interest that some manufacturers put in helping their clients, for example Microchip and Crownhill, this last is incapable to put a simple example of a Masters and a Slave working in SPI communications.

So Microchip doesn't have any examples? There's plenty to be found in the datasheets. And any problems with the SPI module (and there are a couple here and there) are found in the errata sheets, complete with workarounds...
And Crownhill? Well, I don't use the Proton compiler they sell. But it seems to me that if the compiler works and it's still selling well, then it's probably a good bet that the SPI routines it comes with probably work fairly well also. And besides that, how about trying http://www.picbasic.org/forum/ or http://www.google.com . The Search functions work great and I'll bet you can find loads of good examples for code at either.

I have begun to try to start up your routines but they do not work and I do not dare to write in the forums since the answers that they gave you, have been sufficiently frustrating for my.

So, even though the original poster wrote in the forums looking for help because the program didn't work, you assumed that it would actually work for you and it didn't? Imagine that...

Well, your routines seem enough to learn a PIC-to-PIC SPI, so, if you have them working, please, put them here in the forum or send me them by mail.

So what you actually want is somebody else to do all the legwork for you.

I am correct so far?

Hi skimask,

Thanks you very much!, your answer is the answer that anybody can expect from people as you!.

First of all, you say that there are a lot of examples in the Datasheets of Microchip, yes, with many errors, enough , even, to create controversies, see the PIClist, for instance. You suggest to visit the Proton+ forum or to search in Google. These suggestions are offensives. Of course!, I have search though Google, I have visited a dozen of specialized forums and I have not found a simple (only simple!) working SPI routine for a simple PIC to PIC communication in Assembler, nor in PICBasic Pro, nor in PICBasic Plus, nor in Proton, the only thing I have found is a lot of people looking for any good suggestion and all of them received suggestions as yours, nothing. So, you are not correct!.

Second, no, sir, no, I do not assume that anybody works for me, I assume that Internet is a good site to learn anything (I am a simple hobbyst), I assume that if moogle have posted a simple routine looking for help, probably he has not problem ( I say "probably, he has not problem...", I do not say "he is forced to...") to send or to post the same routine free of errors (their routines seem very good but I think there are not NASA's designs. Sorry, moogle, that is for skimask). Moreover, before I have decided to post my message to moogle, I have spent more than one week testing my own and other routines. So, you are not correct!.

Finally, instead of spending your precious time saying the idiot who I am, it will been simpler to put a simple link to one of the many sites in which according with you, there is a simple SPI routine of PIC to PIC. I am correct so far?

Search the posts here. If you can find less than say, 50 answers I've given out to others, I'll write your code for you, test it, and hand deliver it, straight to your workshop, program your chip, and cook dinner for you.

No, you are not correct...so far.
Did I call you an idiot? Nope. Anybody else see that? Nope. Did I imply that? Nope.
Would it have been simpler for me to link you to an SPI routine? Yep. Would you have actually learned something in the end? Nope.
In my little world, it runs right back the old 'teach a man to fish' thing.

Now then, post some code that YOU have written (not just some cut-and-paste from somebody else). And when you can't figure out why it doesn't work or why something isn't doing what you want it to do, you'll figure out what sort of answers I (or anybody that frequents these forums) can give out.

Hi, Skimask

Take it easy ...

My Dear Virolay,

IF you were a PicBasicPro fan ... ( pfffff !!!!) you should have had YOURSELF your first look HERE :

http://www.melabs.com/resources/samples.htm

... I'm really not used to link pics between themselves ( LOL ) ... but straight found THIS:

spimast routine for ... spimaster
Spislave routine for ... spislave !!!

Now, I can understand you're a very great man AND/OR think you really are ...

BUT, that doesn't allow you to write stupidities about suppliers from your second post on this forum ...

" I want this " is definitly not the good key here ... so far we don't know ANYTHING about what you had hoped to realize.

Have a nice afternoon

Alain
