FullDuplexSerial Multi Channel

VG

Hi, I am looking for a single FullDuplexSerial object (code) that can handle multiple channels (each with separate Rx,Tx,Baud and Mode). I could not find any such in ObEx. The versions available can handle only one channel per object/cog. I figured the number of cogs used is high with them. Do you know of any??
I know multichannels reduces the·baudrate since only one cog is handling all channels.
Please enlighten me if I am missing anything else, particularly if there is any data loss.
How much incoming data each prop pin can save in the internal buffer (if any).

Sincerely,
Venkata.

How many channels?

There is a 4 port serial object written by Tim Moore that is available.· You might want to look into.· I have not used it myself but ... it is attached

The 4 port serial object Earl mentions works great. I use it exclusively, even when I need only 1 serial line.

Wow. That's quick and thanks a lot Earl. I will test it right now. I was originally looking for 16 channels. 4 is enough·for my project.

Sincerely,
Venkata.

Hello VG,

you can do 4 channels per Cog

so this gives you 16 channels on 32 IO-Pins in 4 cogs

best regards

Stefan
