using Quad UART

[Archangel]

Thank you for your reply.


As you can see, I need 1 USART. I MUST use SERIN2/SEROUT2 (witch are not good as hardware usart)

This is my problem



So my idea is to use an external USART to bypass the use of SERINOUT2

regards

OK, so I am thinking USART is a hardware thing which works in the background while Mr. PIC does other things in software. SERIN2 SEROUT2 is a bit banged software serial port which can execute 1 instruction at a time, receive data on only 1 pin at a time . . . so why not slave them all on only 1 line and let them speak only with permission from the host. As I see it the host can only communicate with 1 at a time anyway unless using USARTs.
Here is a sample of an lcd unit featuring a ring buffer so you do not lose data. Add to it a CTS clear to send and an RTS ready to send and you can do as Charles suggested, as for controlling 2 USARTS, I have no experience.
