Porting RTOS to Arduino Mega board

Hi all,

I am currently working on an RFID project and using Arduino Mega board for the same.
The project uses two RFID sensors and I must run two events from the sensors simultaneously.
Hence, I am trying to port an RTOS to the Arduino Mega platform for running two processes in the same core.
(1).Can you suggest an RTOS compatible with Arduino mega?

(2)I believe Arduino also supports protothreads. So can we use protothreads instead of porting an RTOS to Arduino Mega??

Thanks in advance :slight_smile: ,

Why not just use the simple system in several things at a time ?
