Sending Binary data using ASCII

[drbanner]

Hello All,

I'm trying to control serial-interface instrument using NI-VISA with a set of ASCII codes, but the instrument reads/sends binary data only. What should I do so that the ASCII codes I send are converted into binary commands for the instrument to read, and that the data I receive is converted back into ASCII?

Thanks in advance

M

Hi M,

first you should define the words "binary commands/data". Then you should know: ASCII is binary too...

You may work with an U8 array. You can easily convert strings to U8 arrays and vice-versa!

sorry, I meant to write bytes

ASCII is bytes. You are still very unclear. As already mentioned, you can create a U8 array. Discussed in hundreds of other threads are other options; Typecast, String control/constant set for hex display, etc.
