Question

I am receiving 2 bytes of binary information via Serial in C.

I am receiving them in a char.

So I need to join the 2 chars to make a int but Im unsure how to do that.. first of all the first byte is in binary format and not char format.. So im unsure how I Can convert it into a useable form for my program.

Answer 1

Just OR them together ?

x = (b1 << 8) | b2;

Make sure they’re unsigned or cast accordingly (shifting signed stuff is nasty).
