I want to send hex data from an Atmega to my PC. I have<br>
a com port component for Delphi which receives Ansii fine. I can see the<br>
comport RX signal flicking ie receiving data in hex format, but I don't know<br>
how to convert it into something I can use/display. <br>
<br>
Currently I have been using the c itoa function, but I have sign issues and it<br>
takes longer to send 65000 than FF so was hoping to go the hex route. <br>
<br>
I presume all higher level programs will have similar issues. <br>

Thanks Wallace.<br>
