[Fixed] Displaying binary data in hex?

[flaxum]

I'm working on an IR program (based off of Vanya Sergeev's), and I was wondering if there's any way to display the data in hex?
Currently, it only displays odd symbols, which do not help very much.
Thanks

if you use printf you can use %x to display in hex format a variable like this:
printf("variable x: %x\n", variable_x);

for each char byte
check isprint(c)
if true print it else print a dot

Following on from weltall's reply, I usually use

Code: Select all

printf("variable x: %08x\n", variable_x);

To zero pad the number out to 8chars, or 32 bits.

Works great, thanks all!
