Programmable Baud Rate in uart.vhd?

Jack,

 

   Is the default baud rate of 9600 changeable for the uart.vhd that is included in the Papilio_AVR project for the Papilio One?   I have an external Bluetooth device that insists on 115200 for the startup communications, though it can be slowed down after that.

 

Thanks,

RonCK

Hello RonCK,

 

I haven't looked at it in a while, but that uart is patterned after the AtMega103 UART, so there is indeed a register that can be loaded to change the baud rate. That uart is designed to be used with a soft processor so I don't know how hard it would be to adapt for stand alone use.

 

You might want to take a look at this uart which might be easier to use standalone:

Jack.
