2 interrupts problem

[neverlog]

Dear All,

I really wish you can help me for the below:

I am doing a RFID controller, I have 8 unit RFID controller(Slave) which linked with each other via BUS(I use ex_PBUSM.c for the communication)

My problem is my RFID controller is always communicate with RFID reader to retrieve and send command/data. I use interrupt for the data receiving thru UART.

My master controller will be communicating with the RFID controller via ex_PBUSM.c method which is also using interrupts.

In the RFID controller, can I use 2 interrupts for RFID reader part and Communication with Master? My highest priority will be on RFID reader part.

Please help. 1000 thanks!

I have found a method call RTOS.

Is RTOS suitable to run 2 critical task which required more than 2 interrupts as both high priority.

Or PIC itself is not meant for RTOS? Any advice will be appreciated.
