Need a way to connect multiple UARTs to a single PIC

Hi,

I need to connect 5 UART peripherals to a PIC.
What are the best options I have to connect these 5 to a single UART interface in the PIC ? I need to be able to enable interrupts to listen data receiving events from each one.

Hello

your question is way too generic
PIC??? 8? 16? 32bit?
all so if you do not have much experience, I recommend using the CCS compiler,
thanks to its high-level libraries allows you to create USART all you want, in almost all I / O pins of your pic.

Regards.

Kushan,
See if this link helps.

Earlier some companies were making quad (16554)and octal UARTs with Fifos available, interfaced to the 8 bit parallel bus, which you can realise out of PIC's I/O lines.That will have the interrupt capability that you want.If you are familiar with programmable logic, you can make one yourself as some free UART cores may be available.
Or choose a PIC that has many UARTs.Rabbit has six serial ports, if you want a readily available 'core module' and which can be directly programmed in dynamic C.With Rabbit, you can get on with your work in a few days .Also try serial bridges like SPI to UART and I2C to UART available from Max and NXP.Also do not forget to see XR, which has good products.In case the data from your peripherals is at a slow speed, think of converting them to RS485 or RS422 and multidrop.Does your PIC have a USB interface? In that case an attractive solution can be there.
