Serin serout problem

[skimask]

that works
Then again it is only one 8 bit sending/receiving, I need four in the serout, but it is a good step.

So it does work, completely, as intended? Temperature is sent over and all that?

Why do you need 4 bytes to go over the link? You can keep doing the math at the receiving end and like I said, temp probably wouldn't ever get above 255C?


Oh...I forgot about the wireless link that was supposed to be there in the first place....
Re-post what you have for code....

[QUOTE=lerameur;30072]the code I have is the code you have on top a couple of posts ago, I am trying to add multiple items to it though

I'm modifying it a bit (adding the manchester encoding stuff) so you can hook up the wireless modules and try it with one byte. Should be easier to add more data after the wireless it working with byte, then to make sure multiple bytes work without the wireless....that's my thought anyways...

[lerameur]

you can look at the first post I have manchester encoding there and it works

[skimask]

It probably does work, but I threw this together....unless I made some silly mistakes, this should work with (and without) the wireless modules, in fact it should work just fine with the wire still attached. Maybe it wouldn't be a bad idea to test it out that way also...

[lerameur]

what are temp1 and temp2 used for in the receiving code ?
because it is used at the end of the program , but the value is not initialized to anything, , no input,

[skimask]

what are temp1 and temp2 used for in the receiving code ?

Whoops....should be hi and lo instead of 1 and 2

temp = ( temphi * 16 ) + templo
