Are you still working on your barcode reader to record the register of your students ?

You do not make it clear at all what you are hoping to achieve. It is theory that you would like, or practical help, or specific programming help. Which pins do you have available, have you any hardware resources available?

You could for example connect a single I/O pin on each PIC. On one PIC you designate (the slave) set the pin to input and on the other PIC (which is then the master) set the pin to output. Then on the slave you regularly keep check of the status of the pin (= 1 or =0 ) in your code, this, I believe, is referred to as POLLING. You can then communicate to the slave by changing the state of the output of the pin on the MASTER PIC.


I do become concerned that this forum, which is a limited resource, by virtue of the fact that its contributors provide their expertise for FREE, will lose the interest of its stock of extremely capable members who are prepared to answer our requests for help and assistance.

I also believe that language is not too much of a problem, as I do not doubt the sentiment of the previous reply.

If I were to undertake learning a complex, information based, subject that relied on me having to ask questions, I cannot begin to understand why I should want to further complicate my life by choosing to do so in a language I was not fully conversant in(unless I was forced to do so). I accept that microchip do not appear to provide datasheets in Italian of French etc, but there are auto-translators readily available now, sure they may make mistakes, but they help. I understand Melabs supplies PBP manuals in Spanish, for example.
To clarify I categorically do not believe that language difference is preclusive to understanding either PBP or, more importantly, to posting on this forum.

However, it is imperative, to at least attempt or be seen to attempt, to construct a well prepared question. I would assume that as a teacher, one has to keep one’s students motivated by such. Otherwise one’s students will become lazy and disinterested and therefore less capable to doing anything for themselves like reading books and spending time researching. They will gradually decrease initiative and begin to expect everything handed to them on a plate, eventually becoming truculent and facetious in attitude.

Microchip provide a range of documents entitled “Tips and Tricks” I suspect there may be something on their site to help evaluate and choose which of the options with respect to PIC to PIC communication that may be suitable. Microchip have a vested interest (ie they make money) in providing information regarding the use of their products to customers of all levels of ability.

Anyway observation for today is:
The quality of the answer is a function of the clarity of the question
