Hi all

I am sending an data out a serial port, but the message is quite large (60Bytes) and I don't really want to allocate that much space for it in the form of an array or similar before sending it.

I would like to simply keep feeding the serial port with "chunks" of data in a fashion that keeps it fed until I have sent the entire message.

I was thinking of using the ring buffer technique with about 10bytes storage, when the value of the buffer was down to about 5bytes I would fill it up again.

Is this the best way to do it?

I am implementing a modbus read command, and generate the data on the fly, rather than storing it in the so called 3xxxx or 4xxxx registers.


Thanks for the thoughts
