Hex Data Stream

Post by Marv »

I have a hex Data stream of 25 bytes. How can I store these bytes without the use of serial.read_IOBUFF (Cicciocb is working that problem)? Also is there any function that I can use to convert Hex Bytes to Decimal or any software routine to do the conversion? Using ESP 8266 Help!! appreciated

How to "store" the incoming data is easy (variables, array).
How to "read" the incoming stream is another matter - it could be read a byte at a time for 25 bytes worth then saved, but if any of the incoming bytes is 0 it will be interpreted as a numeric null and probably mess up the byte count.

I did a project for reading incoming data from a GPS module which perhaps might help...

When serial.IOBUFFER is made available will ascii 0 still mess up the byte count? Out of the 25 byte input at least half of the bytes could be 0.
