Seems to me that the internal baud rate generator is detecting a error
to big for the selected baud rate (aka big deviation) of your serial
configuration.
Try yo lower (or rise) the baud rate of the serial interface, that until
you find a setting that make the PIC happy. if the "happy" baud rate is
a "no-go" for your application then think in using other crystal, may be
20 Mhz... ;-)

Hello,
I have a PIC 16F977 with a 10 Mhz crystal. I am trying to compile the
sample file "16f877_serial_hardware.jal". It compiles fine if I leave
the target clock speed set at 20_000_000. But when I change it to
10_000_000 (since I am using a 10 Mhz crystal) the compiler gives me the
following error:
Compilation started at :6/16/2013 4:05:30 PM
jal 2.4o (compiled May 8 2011)
[Error] (lib/usart_common.jal) [Line 95] "asynchronous baudrate
deviation is too large"
Compiler CommandLine: C:\PROGRA~2\JALPack\compiler\jalv2.exe
"C:\Program Files (x86)\JALPack\sample\16F\16f877_serial_hardware.jal"
-s "C:\PROGRA~2\JALPack\lib" -no-variable-reuse
Errors :1 Warnings :0
Can somebody tell me what to do about this? I don't have any 20 Mhz
crystals on hand and won't be able to get one for awhile.
Thanks,
Shawn
