Usart compile errors 18F4520

[Luckyborg]

using Mr E's Multi-calc's recommended settings

9600 baud

RCSTA = $90   ' Enable serial port & continuous receive
TXSTA = $24   ' Enable transmit, BRGH = 1
SPBRG = 160   ' 9600 Baud @ -0.08%
SPBRGH = 1
BAUDCON.3 = 1 ' Enable 16 bit baudrate generator

2400 baud

RCSTA = $90   ' Enable serial port & continuous receive
TXSTA = $24   ' Enable transmit, BRGH = 1
SPBRG = 130   ' 2400 Baud @ 0.0%
SPBRGH = 6
BAUDCON.3 = 1 ' Enable 16 bit baudrate generator

The code you posted should have been sending data out at 9600 baud with SPBRG set to 25. Set SPBRG to 103 for 2400 baud. The error rate would be a little higher than the above code snippet (not that it would probably matter in the real world).

RCSTA = $90 ' Enable serial port & continuous receive
TXSTA = $20 ' Enable transmit, BRGH = 0
SPBRG = 103 ' 2400 Baud @ 0.17%

Thanks to Mr E

I knew I left that post reply open too long...

I didn't realize I was using an old version. I was still on 1.1.0

Thanks for the update
