I am fairly new to C++ programming and I'm working on a project that will read and parse a 2400baud serial ASCII data stream. For now I'm using an Arduino Uno as my prototyping platform. The stream is comma delimited, continuously repeating, and formatted exactly like this: V=13.7,FV=13.7,V2=00.0,A…

Build a string from the incoming characters then when it is complete (you need an end of message indicator) use strtok to split it at the commas then you can split each substring and turn the number strings into numbers using the strtof function if you actually need the numbers, otherwise just displ…

Thats not a very effective way of doing things. Your wasting alot of memory and string functions are quite slow. It's more efficient to listen for characters as they come in. It's very easy. How about something like below. I just quickly put it together, could contain some error or be made more e…

Thank you raquemis! I'll give that a try. -Mark

char bytebuffer[1]; A one element array? Get real. That whole routine for reading one character from the serial port is riddled with waste.

string functions are quite slow. Do you mean String functions are quite slow or string functions are quite slow ? Not the same thing at all.

Not the same thing at all. Especially since one is true and one is not.

PaulS: Not the same thing at all. Especially since one is true and one is not. That was my point.

PaulS: A one element array? Get real. That whole routine for reading one character from the serial port is riddled with waste. Heard about constructive feedback? you could have asked me why i did that, hearing me out and then giving me advise on how to do things better. Under my opinion readByt…

That was my point. A bit too subtly made, I thought.

ReadBytes needed an array as input, a normal char would generate an error with that function. But the address of a normal char would not.

Need help parsing serial data stream please.
