FREQOUT compiler error on USB Pic

[mindthomas]

That's perfect english...shows how to define a word and a couple of bytes, and how to split them up and join them back together.


What about it?

What about it: It's how the code is used in the USB Script, so how could i get more than only a byte to send? Can you set to bytes together so you can send 255*255?

Well, since the buffer is set up as a bunch of bytes....
You might...just might, be able to split those 'larger' values, WORDS as they're called (2 bytes, highbyte and lowbyte), and place them into the buffer back to back. And retrieve them in reverse order.

Ohh, so you have a number you save in a WORD, and then split you the WORD up in two BYTES and then you send the BYTES, but can i then get them to one number again in visual basic? And can you also do it the other way, so i have a number higher than 255 would like to have send to the PIC?

I Hope you can help me, and it would be great if you could make som code examples

Read the book...again...search the forums. There's plenty of info out there, more than enough.

I have found out... Your code was perfect, i could also just have looked in the book

Then i used your code in the PIC and this code in Visual Basic

Function LOBYTE(ByVal w As Integer) As Byte
    LOBYTE = w And &HFF
End Function

Function HIBYTE(ByVal w As Integer) As Byte
    HIBYTE = (w And &HFF00&) \ 256
End Function

Just so others can see it, if they maybe need it!
