max baudrate

[zuran]

Has anyone tried a baud-rate higher then 19200
9600 works fine
19200 works also fine

38400 does not work
56000 does not work
57600 does also not work

anyone tried this ?

I looked to put the registers manually and it works perfectly

so instead of

Code: Select all

'Usart1_Init(38400)

I use

Code: Select all

' Set baud rate to 38400
	UBRRH = 0
	UBRRL = 12
	UCSRA = 0
	'Enable receiver and transmitter
	UCSRB = ((1<<RXEN) OR (1<<TXEN))
	' Set frame format
	UCSRC = ((1<<UCSZ1) OR (1<<UCSZ0) OR (1<<URSEL) )
