Thread: hex to char problem

hey guys,

i am trying to communicate serially with a camera through my microcontroller

i have to send hex command 56:00:26:00

the uart function only takes in char pointer to send the data

so in char, command is V:nullchar:&:nullchar

nullchar terminates the flow and only V is sent

pl suggest something.

Have you tried sending "56:00:26:00" as a C-style string?

If it is a Canon Camera, take a look at CHDK, you'd find many of this kind of Questions answered in their developer Wiki.
