BAUD1

Action

Changes the baud rate for the second hardware UART.

 

 

Syntax

BAUD1 = var

BAUD1 #x , const

Xmega Syntax

BAUDx = constant

 

 

Remarks

Var	The baud rate that you want to use.
X	The channel number of the software UART.
Const	A numeric constant for the baud rate that you want to use.

 

Do not confuse the BAUD1 statement with the $BAUD1 compiler directive.

 

And do not confuse $CRYSTAL and CRYSTAL

 

$BAUD1 overrides the compiler setting for the baud rate and BAUD1 will change the current baud rate.

BAUD1 = ... will work on the hardware UART.

BAUD #x, yyyy will work on the software UART.

 

Xmega

For the xmega, the X represents the UART number. BAUD means, the first UART, BAUD1 the second UART, and BAUD7 is the last UART. A channel number is not supported.

For the Xmega you need to use a constant for the baud rate. Variables are not supported.
