baud rate converter

baud rate converter using MCU with 2ea UART.
 

baud rate convertor

Just design it then. Time to send a byte might be faster but time for the complete message stays the same.
You need to buffer the incomming data from the highest baudrate.

What experience with uC's do you have? What microcontrollers are you using, what languages do you know?
Post your questions, code, ... here and you'll get there.
When you're lucky, someone here already designed something similar and is willing to post his design (or send it to you)

Make 2 ring buffers :
first for port1 Tx and port2 Rx
second for port2 Tx and prot1 Rx

and work with interrupts
 

I don't think you even need a ring buffer for the low speed to high speed conversion.
And yes, using interrupts is a good idea, although you could probably do this polling too.

I am sorry, what is exactly the function fo this devie you want to build.
thanks,
 

Buffer will be needed if duplex connection is used - data flow is to be in both directions . At least one buffer will be needed for sure when receiving data from high speed Rx and putting into low speed Tx side.

Click to expand...

And maybe, hardware or software "Handshaking" for high to low speed data transfer...
