Communication PIC to PIC?

[droptail]

How do I transfer a value (variable) from one PIC to another? Say w2=25 for example. I now use the SERout command to output an LCD display. Would this be the method, SEROUT and SERIN? How to set this imported value into the recieving PIC variable using PICBasic?

Thanks,

Thanks Steve, I'll give her a try.

what do you do if you have 39 things to send and you do not want to eat up all that space with serin commands.

[mister_e]

39 things to send or receive?

To send => you can even use internal EEPROM or use an array variable.

To receive = > With SERIN2, look for the STR modifier.

ok. I think that I have found a way to get this moving. The problem that I have is that I broke my 16f648a and do not have another. I will be waiting for a while. But between what I have I think that it will work.

I have the programs of my work if you want to look. ironing out the little details to trans u2 ver 7 and still working on trans u1 ver2.

Ah quick question. the attachment MATH is part of u1 ver2. I am getting error leaving me to understand that I don't understand the math behind what is happening within the chip. Since I am doing multiplication and division my information is base 32 rather than 16? Is that what I am to understand?

SerOut B.6,N2400,[w2]

SerOut B.6,N2400,[#w2]

Referrrencing my above example, both get "bad expression" errors when compiling, whats wrong?

[mister_e]

What about

SerOut PORTB.6,N2400,[w2] 

SerOut PORTB.6,N2400,[#w2]

Sho Nuff! Thanks Steve.

After being unsuccessful in transferrring the data from master to server, I now realize there must be some timing issues involved. How to time the transfer, or have slave wait until a successful serin has been made?
